This pasT quarTer was filled with a
number of activities involving the isTT and
several affiliated societies. in total, there
were six trenchless events – beginning
with No-Dig poland 2012 in april, and
ending with No-Dig Moscow 2012 in
June. it is nice to see so much activity in
various countries.
i had the privilege of attending No-Dig
poland 2012 hosted by the polish Foundation
for Trenchless Technology (pFTT) in Kielce
from 17–19 april. The event had over
150 attendees and a dozen exhibitors.
professor andrzej Kuliczkowski was
an excellent host and brought several
top-level administrators from the Kielce
university of Technology to give welcome
addresses during the opening ceremony.
at the Gala Dinner, a number of individuals
received expert statuettes. i was honoured
to receive one of these beautiful statuettes
from the pFTT and will certainly cherish this
award. immediately after the conference,
i had the pleasure of visiting the hobas
plant in Dabrowa Gornicza. it was very
informative as i had the opportunity to see
firsthand the largest CC-Gpr pipe ever
manufactured, which was used on the
project that won the 2011 No-Dig project
of the Year award for New installations.
The 16 th iTTC hosted by the China
society for Trenchless Technology (CsTT)
was held in Zhengzhou from 20–22 april.
There were 50 exhibitors and over 1,200
visitors who attended the event, which
had numerous domestic and international
speakers. The CsTT held their reception
Banquet where several awards were
handed out to members. Once again, the
CsTT put on an excellent show!
i attended the No-Dig india 2012 summit
from 14–15 May in Bangalore, india
hosted by the isTT. Dr Dec Downey and i
participated in a very successful masterclass
training seminar attended by 120 people and
10 sponsoring companies who exhibited.
Westrade should be commended for the
excellent job in organising this event for the
isTT. We hope that this event will be the
start of re-establishing an affiliated society
in india. plans are already underway for
another event in 2013.
The Colombian institute for subterranean
infrastructure Technologies and Techniques
(CisTT) held the second Colombian and First
andean and Central american Congress
and exhibition of No-Dig Technologies and
underground infrastructure in Cartagena
from 17–18 May. i had the pleasure of
attending this event and delivering the
opening presentation. There were
250 attendees and over a dozen exhibitors
who participated in a technical program
containing 26 presentations from both
domestic and international presenters. This
was a significant increase in attendance
from the first event held in 2010. it is great
to see so much enthusiasm in the south
american region.
i recently delivered the Keynote address
at the 2012 underground infrastructure
research (uir) international Conference
from 5–6 June, hosted by the Centre for
advancement of Trenchless Technology
(CaTT) and Benjamin Media in Niagara
Falls, Ontario Canada. The technical
program consisted of 77 papers with
presenters spread over several countries.
Over 400 attendees and 50 exhibitors were
present. The 14 th international Trenchless
Technology research Colloquium (iTTrC)
was held prior to the uir Conference
from 3–4 June. Dr Mark Knight from the
university of Waterloo hosted the iTTrC,
which attracted 16 research participants
from europe and North america. The group
worked on developing the framework for
two papers related to research needs in
pressure and gravity pipeline assessment,
rehabilitation and installation.
No-Dig Moscow 2012 was held from
5–8 June in Moscow and was hosted
by the russian society for Trenchless
Technology (rsTT). in addition to a large
exhibition area, there was a technical
program consisting of papers in three
focus areas: 1) horizontal directional
drilling; 2) rehabilitation and repair; and
3) microtunnelling. Klaus Beyer from
the German society for Trenchless
Technology (GsTT) delivered the welcome
address on behalf of the isTT.
We are busy getting prepared for
Trenchless asia 2012 in singapore from
2–4 July. This conference is co-located
with the singapore international Water
Week (siWW) and will be held in the
beautiful Marina Bay sands hotel. siWW
attracts thousands of attendees from
all over the world. This is an excellent
example of collaboration between
the isTT and the international Water
association (iWa).
i hope that you are planning on attending
the 30 th international No-Dig Conference
and exhibition from 12–14 November
in são paolo, Brazil. The associação
Brasileira de Tecnologia não Destrutiva
(aBraTT) has been busy in preparing the
conference, which will feature excellent
exhibits and a strong technical program. i
look forward to another productive quarter
in spreading the message of the benefits
of trenchless technologies!

Success story
Russia
Achievement:
German Drilling Specialist DrillTec
relied on mts tunnelling equipment to
implement this complicated project in
the Olympian town of Sochi, Russia.
This impressive work was part of the
effort to complete a section of the Blue
Stream Mega Pipeline Project.
An mts800S4 machine was used to
drill a 216 m blind hole at an angle of
13,9° (-24,747%) in complicated soil,
consisting of mudstone, gravel and
boulders. Furthermore DrillTec wished
to recover all machine parts and
equipment once the drilling had been
completed, despite a missing target
shaft.

To achieve this, mts Perforator designed
all parts to be retractable – even
the heavy-duty mixed ground cutting
wheel at the front. Only a steel sleeve
was to remain in the ground, which
helped to stabilise the hole for the HDD
operation, which was to be launched
from this tunnel.
The high degree of professionalism
in both the machine design and
application made this challenging
project to an outright success for
the contractor and enabled a critical
section of the Blue Stream Mega

If you juST read the headlines, 2012
might be considered a difficult year,
what with the weakness of the economy
world-wide, political tensions in many
regions of the world, and even a
prophesy of the world coming to an end
according to an ancient Mayan calendar.
however, when it comes to the trenchless
community, 2012 is shaping-up to be a
pretty good year.
at the mid-point of the year, it is
worth assessing what we already have
accomplished as a group and what the
near-term outlook is for isTT and the
member societies. During the first six months
of 2012, three new societies joined isTT
and several more groups, recognising the
benefits of associating with isTT have shown
an interest in becoming members. For
example, isTT executive sub Committee
member sergio palazzo is taking the lead
in working with the trenchless industry in
argentina towards in the establishment a
new society that would affiliate with isTT.
in May, isTT held a very successful
masterclass training seminar in india, which
attracted approximately 120 attendees,
who gave the masterclass high marks.
Thirty-five of the attendees chose to
become members of isTT. isTT is also a
sponsor of Trenchless asia, to be held in
singapore in early July in association with
singapore Water Week. We plan to hold at
least one more training seminar in 2012 or
in early 2013.
Throughout the year, many member
societies have held or will be holding
their own education and training programs.
When possible, Chairman Dr sam
ariaratnam, or other members of the isTT
Board, attend and participate in these
events. Thus far, Chairman Dr ariaratnam
has participated in the annual conferences
of North america (NasTT), poland (psTT)
and Colombia (CisTT) and is scheduled to
attend the Turkey society (TsiTT) No-Dig.
in addition, Vice Chairman Derek Choi
attended the China (CsTT) No-Dig and
Board member Klaus Beyer of the German
society represented isTT at the russia
(rsTT) No-Dig. all isTT representatives
have been extremely impressed with the
technical quality of these seminars and
the enthusiasm of those attending. These
events are but a few of the many held by
member societies. a full list of up-coming
member society events is posted on
the isTT website, www.istt.com, and in
Trenchless International magazine. There
may be an event near you that you would
want to attend.
isTT launched its new website at the
beginning of the year. We have continued
to make upgrades and improvements
to enhance the site’s capacity to add
value to isTT members and the trenchless
community at large. The new website
has many innovative features including a
page that will show videos of trenchless
technologies in action. These videos will
be linked to the website’s Trenchless
Guidelines allowing viewers to move from
the technical descriptions of a Trenchless
Technology to a video of the technology.
Not visible to the casual visitor to the
website is a new ‘back-end’, which allows
an affiliated society to easily update its
membership information at any time and
to add information on upcoming society
events. isTT secretary Kyoko Kondo
has done a magnificent job in managing
the development and implementation of
this website membership database and
events system.
The highlight of 2012 will be the 31 st
annual international No-Dig to be held in
são paulo, Brazil on 12–14 November.
isTT will present its annual awards at
the event’s Gala Dinner. if you have an
innovative project or product or are
involved in academic research or a student
of trenchless studies, apply for one of
these awards.
Finally, the isTT Board of Directors at
the 2012 Board meeting to be held in são
paulo will vote to add a new member to the
executive sub Committee (esC). Members
of the esC are nominated by member
societies to serve as their representatives
in the day-to-day oversight of the isTT.
a list of nominees will be circulated to
member societies in early October, with the
election of the new member to be held at
the Board meeting on 11 November 2012.
so there is reason for optimism. The
trenchless industry continues to grow.
users increasingly are becoming aware of
the environmental and financial benefits of
trenchless methods. 2012 should be a very
good year for Trenchless Technology.

sAstt visits Zandfontein
depot of Joburg water
As part of the South African Society for Trenchless Technology’s 20 th anniversary celebrations, the
Society attended its first site visit in many years. On 28 February 2012, the Zandfontein Depot of
Johannesburg Water parking lot was crowded with excited society members shaking the hands of
industry friends they had not seen for over a year.
The evenT BeGAn with a brief
presentation about the trenchless
rehabilitation and upsizing of two trunk
sewer lines in Alexandra. the project
posed many challenges due to the extreme
density of residential houses and informal
dwellings in the project area. For example,
inside one informal dwelling, an occupant
was asked if he knew where the sewer
manhole in that area was. the occupant
said that he did and proceeded to move
his bed and pointed to the manhole cover,
which made up part of the floor of his
house. In some instances, parts of informal
dwellings had to be demolished and rebuilt
after the rehabilitation of the sewer had
been completed.
After the presentation, the group boarded
a touring bus for a ride through Alexandra
in order to see the sites in real life. Although
the trenchless rehabilitation posed many
challenges, it was evident when viewing
the project sites how disruptive the use
of open-cut trenching would have been
to those living in the area. the audience
expressed its appreciation for the site visit,
which had been arranged and sponsored
by Insitu-Pipelines Pty Ltd.
Awarding innovation in irrigation
installation
Meanwhile, the south African society
for trenchless technology 2011 Award
of Excellence has been awarded to an
innovative irrigation pipeline project in
the City of Capetown. the City identified
the need for an irrigation supply for the
Rob van Vuuren of Insitu-Pipelines, Tim Pollard of BKS and Zamokuhle Chauke of the City of Cape
Town receiving the Award of Excellence from former SASTT president Andries Lötz.
Green Point Common neighbourhood,
which covers an area of 86 hectares and
incorporates the Cape town stadium. the
natural spring below table Mountain, which
had been used to irrigate the Company
Gardens many years ago, was cited as a
potential supply source.
In order to utilise the spring, a
350 mm pipeline of 5.2 km would need to
be built through the heavily built-up city. the
Although the trenchless rehabilitation posed many challenges,
it was evident when viewing the project sites how disruptive
the use of open-cut trenching would have been to those living
in the area.
3.5 km upper stretch of pipeline was
created by mainly trenchless means in
order to minimise disruption to the very
narrow roadways.
In planning the route, the City located
disused pipes that could be renovated
with pipe cracking and sliplining. In total
2.3 km of old water reticulation pipes
were found and inspected by CCtV
surveys, which were then rehabilitated by
trenchless means.
Directional drilling was used to lay 130 m
of pipe, and 1 km was laid by using open
trench. Care was taken to avoid social
and environmental disruption, this was in
large-part due to the installation taking
place at the time of the 2010 soccer
World Cup. Additionally, the route traversed
numerous heritage sites which crews took
great care to preserve.

society consists of Bosnia, Herzegovina,
Croatia, Macedonia, Montenegro, serbia
and slovenia. In this edition the Istt is
now pleased to report that Istt Executive
subcommittee member sergio Palazzo
is working with the trenchless industry
in Argentina towards establishing a new
society that would affiliate with Istt.
the Istt’s 2011–2013 Strategic
Operating Plan contains three operational
elements: (1) trenchless Education and
training; (2) trenchless Information; and (3)
trenchless Outreach. the Istt’s Outreach
activities support Affiliated societies,
potential members, and the industry at
large. Once a society becomes affiliated
with the Istt, they then benefit from the
shared knowledge, training, and trenchless
events the Istt co-ordinates to strengthen
the industry.
One of the most important events the
Istt delivers, bringing the industry together,

A strategic component of the education
and training mission of Istt is the sharing
of information. While not everyone has
access to, or can participate in, the training
seminars and courses offered by the
Istt, the International society uses other
communication media to inform the public
about the benefits of trenchless technologies.
Trenchless International magazine –
the official magazine of Istt – reports
on the activities of Affiliated societies
and of Istt. If your society would like
to have their events or achievements
covered in Trenchless International,
send your articles and photos through to
news@trenchlessinternational.com
the Istt also has a large library of
technical papers covering all aspects of
trenchless technology, which are available
to members and the public at large. the Istt
website allows for an opportunity to extend
its outreach program to individuals who
cannot participate in Istt’s training courses
and seminars. to find out more information

Finnish society thinks
laterally at IFAt
In May, 22 members of the Finnish Society for Trenchless Technology visited the 2012 IFAT Fair in
Munich, Germany. The members, who came from a variety of backgrounds, including employees from
water utilities, trenches consultants and contractors, attended the three-day conference.
The MeMBeRS of the Finnish society for
trenchless technology (Fistt) attended
a series of educational lectures during
the course of the conference. the Fistt
attended four lectures in Finland on the first
day, and on the second day attended three
lectures in Munich. Of particular interest to
the society were the international lectures
on house laterals. According to the Fistt,
house laterals are a difficult subject for
those in the Finnish water industry, and
the legislation surrounding them is often
unclear. Additionally, the society says
proper maintenance and management of
house laterals is often overlooked. From
listening to international speakers at the
conference, the Fistt wanted to learn
how other countries tackle the issues
associated with house laterals, and take
from the lectures learnings and new
ideas on house lateral maintenance.
the Finnish lectures talked about CCtV
inspections on sewers, Finnish legislation on
housepipes, and how water utilities install
and renovate housepipes.
the first international lecturer was Ian
Ramsey from the United Kingdom society
for trenchless technology, who spoke
about house laterals in Great Britain. His
presentation outlined how legislation has
changed in Britain, resulting in water utilities
taking ownership over house laterals.
His presentation outlined how changing
legislation has complicated the situation in
the UK, leading to a predicament where
utilities only have control and ownership
over half of the lateral.
the second international lecturer was
Astrid Hanzen from the German society for
trenchless technology, who spoke about
the maintenance and politics of house laterals
in Germany. Her presentation stated that
legislation on laterals varies between the
different federal states, with only three states
active in maintaining laterals.
Fistt learned that legislation surrounding
house laterals also challenges water
authorities and trenchless workers throughout
Germany and the UK, and the issue is not
unique to Finland. From listening to the
international speakers the society was able to
gather many new ideas on how the situation
could be approached and improved upon in
Finland. It was also a great cultural experience
for the Fistt, who visited the Munich town,
tasted German asparagus and wheat beer,
and went to see the Allianz Arena.
Fistt arranges education annual events
to promote No-Dig. Fistt has 45 member
companies across Finland.

PE pipe is attractive from an economic and environmental viewpoint.
tough pe pipe materials
ideal for installation
By Andrew Wedgner and David Walton, Borouge
Polyethylene pipes have long been used to renovate ageing pipeline networks to reduce gas and water
leakage levels and to install new systems. In combination with trenchless installation methods, a new
pipeline can be installed at a low cost without disturbing city flow or damaging the environment. Here
Borouge details three innovative case studies.
WhILe PoLyeThyLene (Pe) pipe
is attractive from an economic and
environmental viewpoint, trenchless
installation methods can be demanding
on the pipe, as gouges and scores to
the outside surface of the pipe during
installation can develop into cracks.
In response, polymer suppliers have
developed high stress crack resistant
(HsCR) PE100 materials that are able
to cope with surface damage without
cracking. the stress crack resistance of
the pipe is at least 20 times the minimum
value specified in international standards,
and gives engineers the confidence to
specify PE pipes in the most difficult
installation circumstances.

In Auckland, New Zealand, a 1 km
section of a watermain travelling from
Waitakere Water treatment Plant to
tram Valley Road needed to be installed
under a native forest park using horizontal
directional drilling (HDD).
these areas of native forest are protected
by the New Zealand government thus

permitted. Engineers from water supply
company Watercare services specified that
HsCR PE100 pipe material should be used,
as they were concerned about the difficult
installation conditions.
For the project, 850 x 70.8 mm PE100
pipe was manufactured by tyco New
Zealand in their Hamilton plant in 6 m lengths
using Borsafe HE3490-Ls-H. the pipe
was butt welded to form two 500 m pipe
strings onsite, and externally de-beaded
before installation.
Drilling contractors Central Drilling were
presented with a number of challenges
by the difficult soil conditions beneath the
forest, however, in late October 2011 all
was ready to pull through the polyethylene
watermain. this final stage went without
a hitch and the new main would soon
provide bulk water for the distribution
companies to supply to their customers in

To ensure that the durability of
the system was maintained,
BorSafe HE3490-LS-H PE100
material from Borouge was
used by Jiangyin David Plastics
to manufacture the pipe.
Lining the leaking water mains in
Shanghai
shanghai’s population is growing fast,
and consequently tremendous strain is
put on their water services. While water
companies have worked hard to keep
up with demand by installing many new
watermains, most of the system is still made
up of cast iron and steel pipes, which readily
corrode in shanghai’s acidic water. this
affects the turbidity and the colour of the
water supplied.
Recently, the China Urban Water
Association organised a one day seminar in
shanghai to discuss the different technical
solutions available to renovate and replace
old pipelines. On the following day the
delegates were invited to a project by the
shanghai Fengxian Waterworks Company,
who used swagelining technology to
renovate 270 m of corroded steel watermain
under a wooded area of the city.
A 300 mm diameter PE100 pipe was
pulled through a die that reduced its
diameter, enabling it to enter the old main.
Once in position the load was released and
the pipe expanded to form a close fit with
the ageing host main. to ensure that the
durability of the system was maintained,
Borsafe HE3490-Ls-H PE100 material
from Borouge was used by Jiangyin David
Plastics to manufacture the pipe.
Pipelining in the Middle east
the Daleel Petroleum Company produces
oil in the sultanate of Oman, approximately
300 km west of the city of Muscat. Like
most oil companies, they recycle process
water and then inject it back into the well to
increase oil production.
As the wells increase in age, the level of
hydrogen sulphide and other contaminates
in the process water also increases, which
in turn leads to rapid corrosion of the steel
pipes. One alternative to replacing these
pipes is to use close-fit internal lining made
from PE, which will extend the life of both
old and new pipelines.
For a recent project, 30 km of 8 inch
diameter steel water injection pipe was
lined by United Pipeline Middle East using
the company’s tite Liner technology. to
ensure that the optimum lifetime was

achieved the PE100 pipes were produced
from Borsafe HE3490-Ls-H high stress
crack resistant material by local pipe
manufacturer Muna Noor Manufacturing in
their Muscat plant.
the individual pipe lengths were welded
into strings that were then drawn through
United’s hydraulically powered roller
reduction box, which temporarily reduced
the diameter of the pipe. the PE pipe was
then easily pulled through the steel pipe,
and once in position the load was released
so the pipe could recover and form a tight
compression fit with the bore of the host
pipe protecting it from any future corrosion.
Confidence with Pe pipes
In response to surface damage that
can come about using modern trenchless
technology, polymer suppliers have
produced a range of HsCR PE100
materials to cope with tough conditions
without cracking. these materials provide
engineers with the confidence to specify PE
pipes in very difficult installation situations
and provide high durability solutions.

The ISTT's inaugural No-Dig India Summit 2012, held in Bangalore from 14–15 May, was attended by
more than 100 delegates from cities across India, including senior government officers, contractors and
consultants.
The MAIn ATTRACTIon of the twoday
summit was the Istt trenchless
Masterclass presented by Istt Chairman
Dr samuel Ariaratnam and Past Chairman
Dr Dec Downey. the international experts
delivered four in-depth, educational modules
that highlighted the main technologies and
techniques used in the industry today.
the program was complemented by
case study presentations from a number
of industry suppliers, who recounted their
experiences using trenchless technologies
in a variety of geological conditions both in
India and across the globe.
the exhibition area, featuring ten key
international organisations, provided a lively
backdrop for delegates to network and
to gather information and knowledge on
some of the key techniques and equipment
utilised in trenchless technology. Delegates
showed a high level of interest in the
products on display, and exhibitors are
confident that business will be forthcoming
as a result of contacts they made.

in 2013.
Istt sets
sights on Brazil
From 12–14 November 2012, industry professionals from around the world will come together for the
30 th International No–Dig conference, to be held in São Paulo, Brazil – a country instigating many major
infrastructure projects.
The 2012 ConfeRenCe and exhibition
will mark the first time the Istt’s annual
event has been hosted in Brazil. With recent
investments in infrastructure that is growing
and transforming the country, it is clear why
the Istt chose Brazil to host the largest
and most prestigious trenchless event of
the year.
In the coming years, funds from the Brazilian
government initiated Growth Acceleration
Program will be used to prepare the country
for hosting both the 2014 soccer World
Cup and the 2016 Olympic Games. Funds
have been secured for the modernisation
of housing, sanitation, transport, energy,
and the transportation sector.
President of the Brazil Association for
trenchless technology (ABRAtt) Paulo

liability
• New applications of trenchless technologies
• Public investment programs.
A growing trenchless nation
the Brazilian market for No-Dig projects is
currently expanding. the technology arrived
in the country in the early 1990s, mainly due
to the installation of fiber optical networks
under urban centres, highways and railways.
there is significant projected growth in the
trenchless sector in the coming years. Many
companies are currently being established
in the trenchless industry, working in sectors
such as transport, gas, communications,
electrical networks, and sanitation.
Mr Dequech says “Our demand for
infrastructure, due to two world sporting
events – the 2014 World Cup and 2016
Olympics – is attracting the attention of
foreign companies to Brazil.”
Mr Dequech says many new businesses
are establishing themselves to take on
these projects. While already established
businesses are working to build partnerships
and consolidate the presence they’ve held
since the 1990s.
According to ABRAtt, the trenchless
sector has grown 30 per cent over the
past two years. In 2012, $Us150 million
has been planned for gas infrastructure,
$Us200 million for sanitation works

water utilities in turkey
As part of Trenchless International’s ongoing series examining utilities around the globe, this edition
takes a look at the water authorities providing service to some of Turkey’s largest cities.
TuRKey’S 16 LARGeST cities have
legally separate and financially autonomous
municipal water and sanitation companies
called su ve Kanalizasyon Idaresi (sKIs).
the first utility created, formed in 1981, is
Istanbul’s water authority, IsKI. throughout
the 1980s and 1990s establishment of the
other utilities followed.
sKIs exist in the following metropolitan
cities: Adana, Ankara, Antalya, Bursa,
Istanbul, Diyarbakir, Kayseri, Denizli,
Eski ehir, Gaziantep, Izmir, Konya, Malatya,
Mersin, samsun, and anliurfa.
In 2008, there were 3,225 municipalities
in turkey, including some very small
municipalities. Before the municipal elections
of March 2009, the number was reduced
by 862 through reclassification of small
municipalities with less than 2,000 inhabitants,
bringing the number of municipalities to 2,363.
the turkish society for Infrastructure and
trenchless technology (tsItt) signed an
agreement with the Union of Municipalities
of the Marmara Region (UMMR) on 5 August
2010, which emphasised collaboration
between the two organisations for increased
use of trenchless technology in turkey.
the UMMR was founded in 1975, and is
currently active in eleven cities – Istanbul,
Balikesir, Bilecik, Bursa, Canakkale, Edirne,
Kirklareli, Kocaeli, sakarya, tekirdag
and Yalova.
Istanbul – ISKI
With a population of almost 13.5 million,
Istanbul is turkey’s largest city. IsKI is the
municipality responsible for providing water
and wastewater services to Istanbul.
IsKI was founded under the Istanbul
Government in 1981 as part of the Istanbul
Metropolitan Municipality. the main priorities
of IsKI are preserving water resources,
providing good-quality water services
to the public, and managing and treating
wastewater. IsKI became the biggest public
company in turkey in 1995. the annual
budget of IsKI in 1996 was $Us257.6 million
($tRY471.2 million) and its investment budget
is $Us106.7 million ($tRY195.1 million).
the total service area of IsKI is
5,342 square km. Within this service area, the
municipality manages watermains totalling
15,586 km in length and sewers totalling
12,714 km in length. the transport mains and
distribution networks are monitored using the
sCADA system.
to manage these networks, IsKI has
completed many local and international
projects and investments in water/waste
management and wastewater treatment. As
The Turkish Society for Infrastructure and Trenchless Technology (TSITT) signed an agreement with

DiYarBaKir
a result of these projects, IsKI has 13 water
treatment plants, with a combined capability
of processing 3,608,000 cubic metres
per day, and 15 wastewater treatment
plants in different provinces of Istanbul. As
Istanbul continues to grow, IsKI continues
to build more facilities to cope with the ever
expanding population.
IsKI has determined all of its key targets until
2040 through a Master Plan for water supply
and wastewater discharging. the Master
Plan accounts for metrics such as population,
water requirements, water resources, water
purification, and the recycling potential of
treated wastewater.
IsKI is currently microtunnelling three new
sewage collectors that will provide turkey’s
inland Marmara sea with better environmental
protection. to read more about the project,
turn to page 40.
Ankara – ASKI
Ankara is the capital of turkey, and the
country’s second largest city after Istanbul.
the Ankara Municipality was created in
1949, but it wasn’t until the municipality
management model was created in 1980 that
the Ankara Water and sewerage Authority
(AsKI) was created.
this change brought in a new era of
infrastructure works, including:
• Watershed protection
• Provision of groundwater and surface
water drinking water sources
• Distribution of treated drinking water
• Regularly maintenance checks of the
city’s water quality
• Ongoing maintenance and repairs of
networks and plants.
Ankara’s municipal boundaries expanded
between 1985–2010, leading to a number
of planned projects to cope with the water
demand. At the end of 1999, AsKI had
constructed 5,138 km of transmission
mains, 74 water reservoirs, and 39
pumping stations. Future projects include
constructing 54 new water storage facilities,
25 pumping stations, and the expansion of the
municipalities distribution network, which is
comprised of prestressed concrete, steel and
ductile piping.
AsKI has a rigorous leak detection unit,
which utilises acoustic monitoring systems,
correlation systems, data logger systems, flow
measurement and pressure measurement to
minimise water losses.
Diyarbakir – DISKI
Diyarbakir is one of the largest cities in
south-eastern turkey, with a population of
approximately 850,000. DIsKI is responsible for
the provision high quality water, the collection
of rain water and the treatment of wastewater.
ASKI has a rigorous leak detection unit, which utilises acoustic
monitoring systems, correlation systems, data logger systems,
flow measurement and pressure measurement to minimise
water losses.
the Drinking Water treatment Plant Project
has been planned to overcome recent influxes
of migration to Diyarbakir, urban expansion
and the ageing network that is responsible
for substantial water losses. the first phase of
the two-phase project is now underway, with
the project aiming to be completed in 2025.
the project will secure drinking and industrial
water for Diyarbakir.
Izmir - IZSu
Izmir is the third largest city in turkey, based
on population, and is located in the western
extremity of Anatolia. the metropolitan area
in the Izmir Province has a population of
approximately 4 million.
In 1987, the municipality began the Izmir
Water supply and sewerage Project to
promote better environmental conditions in
Izmir, reduce health hazards, and to bring
about major environmental improvements
and economic benefits in the water supply
and sewerage sector in Izmir. the project
was completed in 1994.
the current water network is divided into
366 regions. to assist with the authority’s
water management plan, the Izmir
Waterworks developed the IZsU Geographic
Infrastructure Information system to store
infrastructure assets in an Oracle spatial
database. the $Us256,953 ($tRY470,000)
system stores data on 4,200 km of water
pipeline, 43,770 water fittings, 2,820 km of
wastewater pipeline, and 74,720 wastewater
fittings. About 300 IZsU personnel access the
data through four websites. IZsU’s 21 branch
offices utilise the data to improve efficiency
and responsiveness to customer requests.
the municipality uses regular monitoring
of the networks to cut-down water losses
by sourcing where underground failures
are located. since the monitoring program
commenced in 2004, water gain has risen
from 20 million cubic metres in 2004, to
47 million cubic metres in 2008.
anliurfa – uSKI
Over the last decade, UsK has played a
large role in infrastructure studies in districts
that lack appropriate sewerage systems, clean
drinking water and adequate rain drainages.
this has lead to UsK constructing
75 km of sewage systems in the following
districts: Veyselkarani, Ertu rulgazi,
Kar ıyaka Esentepe, Devte ti, Ahmetyesevi,
süleymaniye, Direkli, Akabe, Ak emsettin,
Buhara, Mance, Dedeosman, Hacıbayram,
Muradiye, selçuklu, Osmanlı and Hayati
Harrani Parishes.
Additionally, an 8.5 km long sewerage
system for the tOK Residence and Evren
Industry Complex was auctioned and
constructed in February of 2006. A 120 km
water pipe was also completed for delivering
refined water the following districts;
Bahçelievler, Mimarsinan, air evket, sultan
Fatih, Ba larba ı, Yavuzselim, Akabe,
Ak emsettin, Buhara, Mance, Dedeosman,
Atatürk, Osmanlı, selçuklu, Hayatiharrani,
Muradiye, Hacıbayram, topda ı, Yakubiye
and Eyyübiye.
the current administration has taken many
steps towards problems of rain overflows
and flooding. Recently, roads and streets that
were under flood risk, totalling 13.5 km, were
lined with rain drainage canals.
Additionally, anliurfa is home to one of
the greatest trenchless feats in turkey, the
anliurfa Irrigation tunnels.
the tunnels, constructed in connection
with the southeastern Anatolia Project,
are a multi-sector integrated regional
development project of turkey. the tunnels
were commissioned by the state Hydraulic
Works authority and completed in December
2005. the two parallel tunnels run in the
anlıurfa Province of turkey and deliver
water from the reservoir of Atatürk Dam on
Fırat River.
the length of each tunnel is 26,400 m,
with an outer diameter of 9.5 m and inner
diameter of 7.62 m, and they each deliver
328 cubic meters of water per second.
the tunnels are the largest in the world, in
terms of length and flow rate. the turkish
chamber of Civil Engineers lists the anlıurfa
Irrigation tunnels as one of the fifty civil
engineering feats in turkey.
Currently, the state Hydraulic Affairs is
constructing the suruc tunnel in anlıurfa,
which will be the world’s fifth largest water
delivery project.

safety in the shaft
By jules van Leth, hermes Technologie
The renovation of manhole shafts by the centrifugal spray method is a safer option, compared with
manual coating or the wet spray technique, explains Hermes Technologie’s Jules van Leth.
The M-CoATInG SySTeM from Hermes technologie schwerte
is a safe to use manhole shaft renovation technique. the technique
ensures safety onsite, as well as a high level of personal safety for
the operators. the safety procedure has been in development over
ten years, involving planning and responding to clients’ requirements
and feedback.
Highlights of the system include:
• All equipment and machines are securely installed in a trailer or
on a transporter, and cannot slide or topple
• there is a system for tying attachments down or stowing them
away
• Every vehicle is equipped with lights on all sides for easy visibility
in traffic
• the equipment is spaciously designed, to a high technical
standard, and can easily cope with extreme operational demands.
In its M-COAtING system, Hermes technologie offers fully
automated shaft cleaning using high pressure water jets (the
tssR). the latest development to the system is the HDs jet – a
fully automated sand and water blasting jet. the whole process is
set up and monitored from outside the shaft, so there is no need to
enter the shaft.
While the operator may not be working in the immediate vicinity of
the jets, in order to comply with the relevant health and safety rules
they must wear protective clothing.
the tssR – the cleaning rig that travels automatically up and
down within the shaft – can be installed in the gap between the
winch and the top edge of the shaft. the rig is controlled by an easily
accessible, steplessly adjustable limit switch. this avoids the tssR
being raised higher than intended, preventing unintentional injuries.
Even if the operator is briefly distracted, the system automatically
switches itself off when it reaches the set-level.
the distributor unit is equipped with high pressure hoses, a
mortar-flushing hose, and a hose for the hand-lance. An additional
pressure gauge is fitted to the distributor unit, so that the operator
can see immediately whether the system is still at the optimal
pressure. the mortar-flushing hose is also equipped with a safety
valve, so the correct amount of pressure is used when the pumping
hoses perform.
Thanks to the company’s years of experience
and a constant exchange of ideas with clients
and safety experts, the M-COATING system has
achieved the highest level of safety.
The mechanical components
to ensure that crew members can hear each other, and to protect
operators carrying out the work, the engine bay is soundproofed.
A thermal sensor on the control box display gives constant
measurements of the temperature, giving operators an early
warning of overheating.
to help ensure the highest possible protection of the electrical
system, there is a 0.03 mA residual current circuit breaker and an
earth leakage monitor, in addition to all other requisite fuses and a
motor overload switch.
All attachments – including the high-pressure pump – can be
shut down immediately using the two centrally mounted emergency
cut-off switches.
Re-coating
the operator stands beside the shaft during coating and when
supervising the automated coating process. Crew members manning
the mixer are largely protected from dust due to M-COAtING’s
feed hopper.
the operator is further protected by the suction funnel that is
mounted over the feed hopper, and by a protective mask. Water is
automatically measured out, and the mortar is automatically mixed.
the mortar drops into the grout tank and is safely pumped to the
centrifuge motor through sturdy mortar hoses. A pressure gauge at
the pump outlet gives a constant reading of pump pressure.
Once coating is completed, all attachments are flushed through
potable water.
to prepare the rig for leaving the site, all attachments and hoses
are tied down or securely stowed away.
the generator and HP pump batteries are automatically charged
during transport in readiness for the next job. the floor of the vehicle
is covered in a non-slip coating.
thanks to the company’s years of experience and a constant
exchange of ideas with clients and safety experts, the M-COAtING
system has achieved the highest level of safety.

the in and outs
of pipe jacking
By Andrew Marshall, Pipe jacking Association, uK
Pipe jacking is a specialist tunnelling method for installing underground pipelines with minimum
surface disruption. Primarily used for new sewer construction, it is also used for sewer replacement
and relining, gas and water mains, oil pipelines, electricity and telecommunication installations,
culverts and subways.
The PIPe jACKInG Association has been
established for approximately 40 years and
represents contractors, pipe suppliers,
machine manufacturers and other specialist
suppliers in the UK pipe jacking and
microtunnelling industry.
The pipe jacking technique
Pipe jacking is the technique of installing
pipes by driving a line of them through the
ground with hydraulic jacks from a prepared
jacking pit. Excavation is carried out in a shield
forward of the leading pipe as the pipeline is
pushed out of the jacking pit and the process
repeated. Excavation can be by hand or
machine, depending upon the conditions.
Microtunnelling is pipe jacking using remotely
controlled machines, operated and steered
from the surface, generally less than 900 mm
diameter although larger diameters are also
jacked remotely utilising similar techniques.
Forty years ago in the United Kingdom,
pipe jacking was a very basic technique
which used miners working inside a simple
steel shield to manually excavate for the
installation of modified open-cut pipes by
jacking with short stroke hydraulic jacks and
spacers. the pipelines were used primarily
for crossing under existing structures, roads
and railway in stable soil conditions. the
techniques for excavating and controlling
the face, steering the shield and controlling
jacking forces were very crude, with the
result that the pipes installed were frequently
damaged in the process and the line and
level of the finished pipes were often out of
acceptable tolerance.
the possibility of constructing longer
sections of deep pipe by pipe jacking instead
of open-cut excavation had been realised,
but the system’s quality control particularly
in variable soil conditions held back any
significant increases in this market.
the advent of the latest generation of
mechanised tunnelling systems, reliant
upon pipe jacking, that can handle either a
wide range of ground conditions with one
design or be custom made for specific
conditions such as rock, have proved to
be of tremendous benefit to contractors
and clients alike. Mechanisation reduced
unit costs and has allowed clients to carry
out more work for the given budget and,
in some cases, made previously impossible
jobs possible.
Microtunnelling has gained a total
acceptance as clients and engineers,
previously unfamiliar with the technology are
now specifying its use with confidence.
Microtunnelling machines (250 mm –
900 mm diameter) are essentially miniaturised
versions of full faced tunnel boring machines.
their development generated the requirement
for the remote control of all functions. these
include the operation of the shield machine,
jacking system, line and level control, soil
removal and pipe lubrication.
Microtunnelling systems are effective in a
wide range of soil conditions and are reliable
over lengths of 80 m at 300 mm diameter
and up to 200 m at 900 mm diameter.
these same remote control features were
then adopted in larger diameter machines
of 1,000 mm to 2,500 mm with equal
reliability and increased versatility. these

larger machines can cope with an even
wider range of ground conditions, as well as
installations of far greater single drive lengths
by adopting the use of interjacks.
As with all tunnelling processes, the
geological conditions determine the most
suitable excavation and face support
methods. As a result, a range of machines
with various excavation and ground support
characteristics are now available to achieve
economic installations across the entire range
of ground conditions from soft, unstable soils
through to solid rock.
environmental issues
For tunnelling, and many other construction
processes, environmental considerations are
now becoming so important as to exert a
major control on the technology and the
economics. A particular challenge to the
tunnelling industry relates to the management
of tunnel spoil. this spoil should be re-used
in other works rather than disposed to
landfill. However, in practice, much material
has to be landfilled because it is too wet
to be re-used. the spoil from all types of
tunnelling can be difficult but that from slurry
tunnelling, the most widely used procedure
for small projects, is particularly problematic.
In slurry tunnelling, slurry is pumped into
the face of the tunnelling machine where it
mixes with the cut spoil. the spoil-slurry mix
is then pumped from the face to a surface
cleaning plant. In the cleaning plant, spoil and
liquid are separated, the spoil for disposal
and the liquid for return to the face. the liquid
thus becomes a carrying fluid transporting
the spoil from the face to the surface.
Machine excavation is now used for
over 95 per cent of UK tunnelling and
the majority of these tunnels employ slurry
tunnelling. Furthermore, slurry excavation
is essential in many water-bearing soils as
the machine face is sealed which prevents
groundwater inflow and the risk of tunnel
flooding and dewatering induced settlement
of neighbouring buildings.
With the anticipated growth in the use
of trenchless systems as new legislation
is introduced and the research and
environmental benefits of pipe jacking
become recognised the Pipe Jacking
Association is currently developing a carbon
calculator that will provide an immediate
assessment of greenhouse gas emissions for
pipe jacking and microtunnelling compared
to disruptive open cut construction for
sewer and other utility installations. this is
being developed by tRL, the UK’s leading
independent centre for transport research
and consultancy.
Pipe jacking research
Academic research has played a major
role in the development of pipe jacking.
A 'state of the art ' review, carried out
by the Construction Industry Research
and Information Association (CIRIA) and
commissioned by the PJA started the ball
rolling. Five areas of research were highlighted:
• Friction loads in different ground
conditions
• Load/deflection characteristics of the
joints with different packing materials
• the effect of cyclic loading on the pipes at
intermediate jacking stations
• the effect of lubricants in reducing friction
along a pipe
• the development of a site investigation
test suitable for the prediction of friction
forces.

projects have been undertaken, the majority

Microtunnelling mapped
for Marmara sea
ISKI, Istanbul’s Metropolitan Water and Sewerage Municipality, has commenced three new microtunnelling
projects that will provide Turkey’s inland Marmara Sea with better environmental protection.
The ThRee MICRoTunneL sewage
collectors, named Gurpinar, silivri and
Canta, have a combined total length of
6,016 m, with a diameter of 2,000 mm.
Once the three sewage collectors
are functional, sewage coming through
Beylikduzu south Coast will be transferred
by the 2,009 m long Gurpinar sewage
collector to the Ambarli Advanced Biological
sewage treatment Plant.
the 1,807 m long silivri sewage collector
will transfer sewage coming through the
villages of Gazitepe, Alipasa, Kayalidere
and Fener to the silivri Advanced Biological
sewage treatment Plant.
In Canta East Coast, sewage will be
transferred by the 2,000 m long Canta
sewage collector to the Canta Advanced
Biological sewage treatment Plant.
Getting technical
the three tunnels will be constructed
using tunnel boring machines (tBM). the
machines have 3 m diameters to avoid
disturbing the environment and above
ground structures. these machines being
utilised can perform mechanical digging
under the varying soil and topology
conditions that will be encountered in the
three tunnels.

talking on the machinery, an IsKI
spokesperson said “these machines grasp
the bevel drives on the cutters and conduct
the boring process. there are two crucial
powers to conduct the tunnel boring process.
“the cutting head pushes towards
the bevel drive. the rotation of the head
combined with the pushing force to the
drive enables the digging process.
“the ground the tBM excavates is
transferred to the chamber behind the
cutting head by the wings on the bevel
drives. the conveyor in the chamber
transports the extracted material away from
the tBM for removal. “
Progress to date
Construction works began in February
2012, and it is expected that the projects
will be completed in the first half of 2015,

tunnelling success
down Under
The Melbourne Main Sewer Replacement, an Australian project upgrading the historic century-old main
sewer in Melbourne, has progressed well over the past 12 months and was commissioned in May 2012,
tracking on schedule for completion in mid-2012.
The MeLBouRne MAIn sewer Replacement (MMsR) involves
the construction of approximately 2.3 km of new sewer in and
around inner-city Melbourne.
the new sewer, which begins in the Docklands precinct, crosses
the Yarra River upstream of the Charles Grimes Bridge and
continues into Port Melbourne, is being built with the assistance of
a specially-designed tunnel boring machine (tBM).
the MMsR is an important project for the city that will deliver health
and environmental benefits to meet the future growth of Melbourne.
Major developments
2010-11 has seen many significant advances made on the
project. the 140 m, on-grade crossing of Melbourne’s iconic Yarra
River was completed in February this year, following the installation
of the final section of 2.4 m diameter pipeline. Construction was
undertaken in three stages to ensure the Yarra River remained open
to river users for the duration of works. specialist divers worked
in zero visibility conditions, installing sections of the pipe within a
wet cofferdam.
Another major development occurred in April 2011, when the
project’s 164 tonne, 93 m tunnel boring machine (tBM) completed
Floating pipe into cofferdam.
the final section of tunnel to emerge at the south Wharf shaft site
in the Docklands area. this second and final major tunnel drive on
the project marked the completion of over 18 months of tunnelling
under Melbourne’s inner suburbs.
Project challenges
At the project’s beginnings in 2005, Melbourne Water, together
with project partners, contractor John Holland, designers GHD
and project manager Aurecon, knew that the MMsR would not be
without its challenges.
“the 875 m final tunnel drive was one of the most challenging
engineering feats of the project due to difficult geological conditions,
which saw the specially designed Earth Pressure Balance (EPB)
tBM steered through soft clay-like Coode Island silt, and around
critical infrastructure, including the M1 Freeway,” said Melbourne
Water Project Director Phil Corluka.
“In undertaking these essential replacement works, the MMsR
team has developed a good understanding of geology and
hydrogeology, being the first to mechanically tunnel through the
Yarra Delta, most notorious being the Coode Island silt, which
provided significant challenges to the original constructor in the
Branch and reticulation sites.
1800s. the learnings gathered on this historic project provide
fantastic knowledge for future projects and for soft ground tunnelling
as a whole.”
In addition to two major tunnel drives and a river crossing, the
MMsR also encompasses the construction of 1.9 km of localised
branch and reticulation sewers. to minimise impacts on the local
community, trenchless technology was effectively utilised to install
smaller reticulation pipes ranging in diameter from 300–500 mm.
smaller shaft sites, situated within densely populated suburban
streets, have been used to complete this intricate set of works.
vital infrastructure
the MMsR is an important project that will deliver health and
environmental benefits to meet the future growth of Melbourne. the
new sewer will have three to four times the capacity of the existing
sewer and will service the CBD and the fast growing Docklands
precinct, which is expected to be home to 20,000 residents and a
workplace for 25,000 in 15 to 20 years' time.
the MMsR is currently tracking ahead of schedule, under budget,
and has successfully overcome many challenges encountered
throughout construction. Early identification and mitigation of these
challenges has been paramount in achieving many milestones
on the project. Identifying potential risks and issues has been
fundamental in planning for both the successful completion of
construction, and the quality of the final product, which will service
the city of Melbourne for another century.
The new sewer will have three to four times
the capacity of the existing sewer and
will service the CBD and the fast growing
Docklands precinct, which is expected to be
home to 20,000 residents and a workplace for
25,000 in 15 to 20 years' time.
Final tunnel breakthrough.
Looking ahead
With fresh climate extremes breaking records in 2010-11, the
importance of a robust network of water supply, drainage and
sewerage infrastructure has become clearer than ever. Mr Corluka
said that as Melbourne Water works towards the completion of the
MMsR, and looks ahead to the next infrastructure installation and
rehabilitation projects, trenchless technology will continue to assist
in the delivery of their works.

the short and tall of pipe
rehabilitation
The water and sewage infrastructure renovation market is particularly challenged by pipes with
extremely large or extremely small diameters – spiral-wound pipe lining provides one of the most
minimally invasive techniques for these difficult pipe ranges.
SPIRAL-WounD PIPe LInInG was
developed in Australia in 1978 under the
name sPIREX and marketed for the first
time under the name Rib Loc in 1979. In
situations where standard liners would be
challenged by these impossible operating
limits, the spiral winding technique provides
a novel solution.
forming a pipe from a plastic strip
A winding machine is positioned in the
shaft and produces a new pipe by either
pushing or pulling the growing spiralwound
pipe through the structure being
rehabilitated. this process works due to the
design of the profile strip; the edges of the
strip have friction and a tongue-and-groove
locking system. Or, in special cases, the
tongue-and-groove locking is replaced by
a welded joint.
structural and engineering features that
distinguish spiral-wound lining from other
rehabilitation techniques include:
• Completely trenchless installation
• Minimum reduction of pipe diameter
• Caters to all static loading conditions
• Mechanical, chemical and thermal
resistance to sewage
• same service life as a new pipe
• Rapid completion of the work without
disturbing the urban or environmental
conditions above ground.
A representative from sekisui says “the
available spiral-wound pipe technologies are
ideal for pipes with unusually large or small
diameters. For instance, below a certain
dimension – approximately DN800 mm –
cured-in-place pipe (CIPP) liners can be
difficult to fit through shaft structures.
“to install a CIPP for these diameters,
the shaft cone is often removed or work
is performed using an installation trench.
trenches are also often utilised for lining
short pipe sections in nominal sizes that are
large enough for a person to enter.
Schematic diagram of the spiral-wound pipe lining SPR PE (Ribline).
“Comparatively, the endless profile strip
for a spiral-wound pipe always fits through
an inspection shaft, regardless of the size of
the structure. In these cases, spiral-wound
pipe technology provides the most minimally
invasive rehabilitation solution on the market.”
forms of spiral-wound pipe lining
since 1978 several techniques have
evolved, which are now marketed almost
exclusively by the sPR Group and deployed

by subsidiaries KMG and Rabmer in Europe,
Heitkamp in the Us, and licensed partners
in Asia.
SPR ex (expanda)
Due to demand for a flexible liner that
could be adapted to varying nominal widths
of the old pipe, sekisui Rib Loc developed
the sPR EX – a spiral-wound pipe capable
of expansion.
It still employs PVC strips, but the strip
utilises double tongue-and-groove locking.
the primary lock is designed to be able to
slide after being wound. the secondary lock
binds during the winding process, however,
a special cutting wire is also wound into the
pipe that can ‘unlock’ it. the pipe is wound
to a smaller diameter than required and when
the target shaft is reached, the cutting wire
is pulled. this progressively cuts the bonded
secondary lock along its entire length. When
the liner is fixed in place in the end shaft, the
liner slides in the primary lock and expands
radially until it lies against the wall of the pipe
as a close-fit. sPR EX is used in circular
profiles in the range DN200–750 mm.
SPR Ro (Rotaloc)
the sPR RO technique, known on the
market as ROtALOC method, can currently
be used in circular profiles DN800–1,800 mm,
and is not limited by the material of the pipe
being rehabilitated. the system is based on
endless PVC profile reinforced by t-bars, with
single tongue-and-groove profile locking that
ensures lasting friction-locking in the windings.

welded by an extrusion welding machine
connected to the winding machine. the
winding unit is stationary in the shaft and
the liner is wound into the sewer from
it. the annular space is sealed in order
to stabilise the position of the liner. sPR
PE can currently be used for sizes up to
DN3,000 mm, and is a virtually unrivalled
trenchless rehabilitation technique for this
large diameter range.
Special profiles: the SPR method
A representative from sekisui says “A
step forward in the evolution of spiral-wound
pipe technology was the development of
the sPR process by the sekisui Chemical
Co. the advantage of the sPR is that it
allows pipes of any geometry to be wound –
up to a nominal diameter of DN5,500 mm.”
the sPR process uses PVC and integrates
a w-shaped steel profile for reinforcement
into the profile strip. similar to sPR RO, the
winding frame is not stationary in the shaft,
but moves through the structure ahead of
the liner.
though the pipe is not touching the
structure being rehabilitated, and therefore
cannot draw on it for structural integrity,
the strength of a sPR installed does not
solely depend on the liner. the pipe is
installed with a precisely defined diameter
and exactly centred when secured in the
sewer. A system of spacers ensures that

the required annular space is uniform
throughout. the annular space is filled
section by section with fast-flowing, quicksetting
mortar during the winding process.
the sPR liner then acts as a shell for
the installed mineral wall – and the wall’s
strength dictates the static performance
data of the entire system. the new wall
is also permanently separated from the
sewage by the PVC liner, which eliminates
attacks of sulphuric acid on unprotected,
cement-bound surfaces.
A representative from sekisui says “sPR
is often the only rehabilitation solution for
problematic large profile structures with
extremely poor accessibility – only requiring
a standard inspection shaft for entry. sPR
can also achieve bends, which allows
renewal of historical central sewer networks
which contain frequent bends.”

A burst of inspiration
in Germany
Here Trenchless International looks at two pipe bursting case studies where STG Braunsberg uses
Tracto-Technik equipment for fast installation to fight rising flood waters and to renovate pipe under
a busy road.
A race against the Rhine floods
stG Braunsberg, operated by brothers
Günter and Hermann Braunsberg, were
awarded a pipe bursting contract replacing
pipes near Germany’s Rhine River. the
company was given a construction time
frame of just twelve weeks in order to avoid
rising seasonal groundwater. Investigation
ground bores were sunk to a depth of 8 m.
the bores revealed the groundwater level
had not been reached, and with a working
pit depth of roughly 7 m it was still necessary
to constantly check the level of the Rhine
River and to be ready for all eventualities.
Within the twelve week construction
period, the operating pits had to be
constructed, the pipe replacement
completed, the pits had to be re-filled and
the ground surface reinstated.
the main operations focus of stG is
cable installation and canal construction,
however the area of trenchless renewal
and repair of pipes is an expanding area
of the company. stG has made significant
investments in pipe bursting technology,
and owns three static Grundoburst
machines, manufactured by tracto-technik;

force, a Grundoburst 800 G with 80 t of

pulling force, and the company’s largest and
most recently obtained machine, a 2,500 G
with 250 t of pulling force. stG’s drilling
inventory covers trenchless renewals by pipe
bursting for pressure and sewage pipes up
to ND1,000 mm.
Despite the challenges posed by the water
levels and short time frame, stG was able to
utilise tracto-technik equipment to get the
job completed on schedule.
stG Company Director Günter Braunsberg
said “We are convinced by the technical and
economic advantages of pipe bursting. In
comparison to open trenching, there can
be great savings on civil engineering from
reduced construction times, depending on
the installation depth. the pipe bursting
method allows for a pipe diameter increase
from one to two nominal widths. Also, almost
all pipe materials can be cracked and pulled
in. From my point of view, pipe bursting
technology can be applied more often than
contractors and planners assume.”
under the roads of Düsseldorf
In Düsseldorf, the renewal of the project
was a worn out 127 m long concrete water
pipe of ND500 mm, installed in the 1950s.
the pipe ran under the intersection at the
Rhine Allee and Paris street, situated outside
the Heerdter Hospital. to further complicate
the project, the pipe ran along the centre of
the road.
During the pipe bursting project, traffic
access to the hospital could not be
interrupted in any way. this meant that
all traffic passing through the site, and
local residents and busses would still need
access through the works. It was also
important that access was maintained to
most parking spaces. Due to these strict
conditions, use of open-trenching was out
of the question.
Tough terrain
Ground investigations showed that the
area around the old pipe was a ‘binding’
soil (comprised of a loam-sand mixture
and loamy sand), which would ordinarily
rule-out the pipe bursting method. Also,
the old pipe was being expanded from
500–610 mm diameter, which would
displace the surrounding soil. Because the
old pipe was lying on a concrete footing,
soil displacement downwards would not
be possible. Due to compact soils, the
depth of the pipe would create higher
displacement resistances.
the section of pipeline being replaced
required three separate installations of 40 m,
43 m and 44 m lengths. the machine pit
was 6.8 m deep, 6.5 m long and 2.5 m
wide. Head pits measured 4 m by 2 m and
were excavated diagonally to the pipeline, to
account for the road intersection. the pipe
installation pit at the end of the bursting path
was also constructed parallel to the pipeline,
with a length of 3 m and a width of 2 m.
Safe investigations
Due to the close proximity of the hospital,
it was important to make sure the installation
caused as little vibration as possible, so all
pits were equipped with supporting sheet
boards. Furthermore, the supply mains and
waste disposal lines had to be carefully
investigated and secured when constructing
the pits.
there was also a possibility the site
rested on wartime explosives. the KBD
(the explosives disposal squad) concluded
it was only necessary to carry out safety
investigations in the pit areas – rather than
the entire project site – because the pipe
bursting technique would allow a safe
distance for crews. safety inspections
showed the site was void of explosives, and
the project could progress.
After pit construction, crews could
begin installing the Grundoburst 2,500 G
bursting rig. Initial plans were to use the
Grundoburst 1,250 bursting rig. However,
as ground investigations revealed expected
soil displacement resistance, stG decided
a greater pulling capacity was needed and
chose the Grundoburst 250 G. the rig is
operated using a tt B 250 hydraulic power
pack (127 kW motor effective capacity).
Bursting with QuickLock
A special characteristic of Grundoburst
technology is the QuickLock bursting rod,
which works by being pushed through the old
pipe, then reversing the rod with the bursting
tool, expander and new pipe attached. the
advantage of QuickLock rods is that the single
burst rods are linked together and therefore
don’t require assembly by screwing, which
makes them less time consuming to install
and less susceptible to dirt lodging in the
connections. the rods for this project were
140 mm in diameter.
In order to keep the pits as small as
possible, stG decided to use the bursting
method with 1 m, 560 mm in diameter
sections, manufactured by Egeplast. the
Innovators in Trenchless since 1962
Pipe bursting
with the proven
cutting technology
sL PP-B pipe is manufactured with PP-HM
material, which has a high E-Module rate. this
gives a high strength and surface hardness,
and the pipe’s smooth inner surface and
low roughness ratings improve its hydraulic
performance. the pipe also has a bright
inner colour, which is inspection friendly and
provides optimum conditions for camera
inspection. the joint seal system, with the
triple-lip-seal, is locked by clicking together.
When reversing the bursting rods,
the old pipe was broken open with a
630 mm diameter expander and the new
pipe was then simultaneously pulled into the
same path. In the installation pit, the pipe
length was extended with rods and pipe
lengths. to achieve this, the single pipes
and the expander had to be tensioned
tightly together with a hydraulically
operated Burstfix unit. the tensile strength
is transferred via a rod – also with the
QuickLock function – of 54 mm diameter,
which runs through the continually extending
pipe length. A guiding track was applied in
order to connect the single pipe lengths as
quickly as possible.
shortly ahead of the third head pit, after
approximately 80 m of the 130 m installation,
the pulling forces reached almost 200 t.
Fortunately, the flexibility of the Grundoburst
system allowed crews to overcome this
obstacle. the engineers from stG decided
to unhook the pipe length that had already

how to capture more customers
with content marketing
An innovative marketing whitepaper has been released by Infrastructure Marketing Solutions, a division
of industry publisher Great Southern Press. Here, Jacinta Hannaford, Infrastructure Marketing Solutions
Manager, outlines the importance of implementing content marketing strategies to promote your company.
The TRenChLeSS InDuSTRy is a
competitive market, and potential clients
do their research before they even reach for
the phone.
Constant changes in the industry mean
that the market can be difficult to navigate
and tap into, often creating a competitive
environment even in sectors where there
are few industry players.
On top of this, the widespread use of
the Internet for personal and business use
means that prospective clients of trenchless
businesses now have a lot more power than
they did in the 1990s and even 2000s.
Marketing must now take time to engage
prospective clients, who are spending
more time on researching and educating
themselves.
All of this means that companies have
to work even harder to get their message
across by properly blending traditional
and new marketing techniques, which
has caused content marketing to grow in
popularity.
“Content marketing is a strong instrument
to have in your marketing toolkit, but to do it
successfully you need to stop thinking like a
marketer and start thinking like a publisher,”
says Ms Hannaford.
“Publishers are experts in considering the
information needs of their audience in order
to pull them to their media channels.”
About the whitepaper
the Infrastructure Marketing solutions’
whitepaper, titled The ultimate guide to
capturing more customers with content
marketing, will be made available to all
new and renewed Trenchless International
magazine subscriptions for a limited
time only.
Ms Hannaford says that this resource will
help businesses in the industry understand
how to create and implement strategic
content marketing that creates profitable
results from customers.
the whitepaper includes:
• Content marketing fundamentals
• Integrating content marketing with
traditional marketing
• Putting together your content marketing
plan
• ten most used forms of content marketing
• What platforms to use for your content
marketing objectives
• Measuring performance
• three templates to get you started

Rejuvenating
an old seoul
Korea Water Resources Corporation was able to celebrate the
completion of Phase 1 of the Seoul Metropolitan Multi-regional
Water Supply System Rehabilitation Project after five years
of design and construction. The May ceremony saw many
distinguished guests in attendance including Japan Society for
Trenchless Technology Chairman Taigo Matsui and ISTT Executive
Sub-Committee member Robert Toyoda.
The state of pipes prior to rehabilitation.
ConSTRuCTeD In 1979, the seoul
metropolitan area raw water conveyance
facility was deteriorating. the owner of the
facility, Korea Water Resources Corporation
(K-Water), took on the challenge of
rehabilitating the facility.
After careful consideration of the
workability, environmental aspects and
economic feasibility, K-Water decided
to rehabilitate the more than 30-year-old
pipeline with dry-type automated equipment.
Dry-type automated equipment has
many advantages compared to traditional
trench methods, such as reducing the
time required from construction, minimising
environmental pollution, and reducing civil
complaints and construction costs.
the process involves dewatering and
removing residue then drying the inside of
the pipeline to scrape and blast the surface
to prepare it for the primary and then
secondary painting.
this was the first time dry-type automated
equipment was adapted to large diameter
water supply pipelines.
Project overview
the facilities, which were built between
1973–1978, include an intake pumping
station with a capacity of 1.2 million
cubic m per day and a 91.5 km steel
Equipment performing the ‘scraping’ process.
pipeline with a diameter ranging from
800–2,800 mm. there was also an 8.5 km
aqueduct tunnel with a diameter ranging
from 2,800–3,500 mm.
Located in seoul City, the project scope
included rehabilitating 53.9 km of the 800–
2,800 mm pipeline in the following lengths:
• 2,800 mm – 3.4 km
• 2,600 mm – 1 km
• 2,200 mm – 47.9 km
• 1,800 mm – 1.6 km.
During the rehabilitation project there were
24 temporary manhole units over 32 km of
pipe. the interval between two temporary
manholes was approximately 1–2 km. Many
of the sections contained double pipes. With
the double pipelines, K-Water was able to
supply water to consumers via one pipeline
while the other was being rehabilitated.
Once the temporary manholes were in
place, the contractors drained off the water
to a nearby river or rain water system by
Blasting equipment removing old paint so a surface treatment can be applied.

use of gravity or a pumping station. the
next step was to remove the residue by
waterjetting. the pressure was kept under
200 bar and the water drainage rate was
18 metres per hour.
Keeping it dry
It was important that the inside of the
pipelines maintained an adequate dryness
for quality control.
“to control the relative humidity, we had
to keep it below 85 per cent and wind
speed between 1.5 metres per second to
3 metres per second,” K-Water’s Yong
Hoon Chang said.
For the scraping and blasting process, the
project removed an average of 3,000 μm of
existing paint. Complying with ssPC-sP10,
K-Water removed the closed dried-paint
and applied a surface treatment that
would maintain at least 50μRz in surface
illumination intensity.
Primary painting was completed within
four hours after the surface treatment,
which was done to maintain more than
500 μm in painting thickness. this was
inspected once completed.
The equipment
“the process was simplified through
repetitive forward-backward work within the
pipe and by letting the equipment travel a
1 km distance in one run, the construction
was able to be completed in a promptly
manner,” Mr Chang said.
A single input of equipment eliminates
allows contractors to maximise the primer
painting time within the four hours.
Advantages
K-Water said that this project has
shown the many advantages over drytype
automated rehabilitation. Using this
trenchless method maximised the economic
effects by reducing traffic restrictions
and compensating costs through the
deteriorated pipeline.
Mr Chang said “We could save $KRW206
billion ($Us196 million) in construction costs
compared to new construction. Also we have
social and indirect economic effects such as
no traffic jams, reduction of atmospheric
pollution, dust scattering and noise.
“We extended a 30-year-old pipeline’s
lifetime by more than 20 years, by
rehabilitation.”
K-water, Gs E&C and ssangyong E&C
take an advanced and leading position in
the field of large water pipeline rehabilitation
by improved technology development.
After careful consideration of
the workability, environmental
aspects and economic
feasibility, K-Water decided
to rehabilitate the more than
30-year-old pipeline with drytype
automated equipment.

Renovating pressure pipes
using the CIpp process
By Kaleel Rahaim, Business Manager Remediation Polymers Interplastic Corporation
The cured-in-place pipe process has been used since the early 1970s to renovate deteriorated
pipelines. The process was first developed for gravity pipelines and has found some limited applications
in renovating pressure pipelines.
CuRRenTLy oveR 12 million ft
(3.9 million meters) of pipelines are being
renovated annually in North America using
the cured-in-place pipe (CIPP) process.
Many more pipelines around the world are
being renovated using this process.
Designing the liner to be cost effective
is a key component utilising this process
successfully. the liner must perform as a
new pipe and last a defined amount of time.
In gravity pipes, liner failure is generally
due to buckling. the liner simply cannot
support the loads to which it is exposed.
the design of these liners takes those
loads into account. the design equations
consider the loads, hydraulic, soil and any
dynamic loads. the equations basically
consider flexural properties in the design of
Renovating pipe using CIPP.
Currently over 12 million feet (3.9 million metres) of pipelines are
being renovated annually in North America using the cured-inplace
pipe (CIPP) process. Many more pipelines around the world
are being renovated using this process.
a gravity pipe CIPP liner. tensile properties
are only considered for the inversion or pull
in place forces that may be exerted on a
liner prior to final liner installation.
the stiffness (flexural modulus) of the
liner is dependent on the resin used as well
as the construction protocol. the felt bag
contributes nothing to the ultimate physical
properties of the constructed liner. It acts
primarily as a carrier for the resin.
For several years there have been limited
applications utilising the CIPP process to
renovate pressure pipelines. some of the
most common pipelines being renovated
include force mains, gas transmission
lines and a small number of drinking water
lines. Limitations in products available and
dependable processing methods have
to date limited using CIPP for renovating
pressure lines. Many of those limitations are
being addressed or have been addressed
and the future of CIPP in that market looks
promising. Estimates for the number of linear
feet of pressure pipelines that need renovation
exceed the number of feet of gravity pipelines
that need renovation.
Renovating pressure pipelines
Renovating a pressure pipeline is a very
different operation. A new set of physical
property concerns as well as new construction
methods must now be considered.
In gravity lines, buckling concerns
determine the design equations. In pressure
lines, tensile properties become important.
Liner failure is generally due to internal
tensile forces. the thermoset resins alone
in a felt liner are generally not capable of
satisfying the mechanical property needs
of most pressure lines. With this in mind,
liner engineering becomes important. the
liners constructed for the CIPP process for
pressure pipes are either liners constructed
entirely of reinforcement media or that
contain reinforcing media. this media may be
fiberglass, aramid fibers, or carbon fibers, or
a combination of the above. Felt may also be
included in the ‘hybrid’ systems.
the resins used may also be different
than those used for gravity lines. Vinyl ester
and epoxy resins are the more commonly
used thermoset resins for pressure lines.
the mechanical properties of the resins
designed for pressure pipes work in
synergism with the reinforcing media and
the fatigue resistance is much better than for
polyester resins. Fatigue is a phenomenon
that deteriorates liner properties due to
‘flexing’ of the liner caused by pressure
variations in the line.
Designing liners for pressure lines is a much
more complicated process requiring a very
clear definition of the variables associated
with the project and the construction of
the liner. Adhesion between the resin used
and the reinforcement is crucial in reaching
optimum mechanical properties.
Along with different liners and different
resins, the processing of CIPP liners in
pressure applications is different. since
there is no easy access to pressure lines,
some digging is generally required to
access the deteriorated pipe to be relined.
Reinstating any services in the pressure line
is also a more complicated procedure than
for gravity lines.
With pressure lines, adhesion between
the liner and host pipe must be taken
into consideration. If there is adhesion,
lateral considerations are different than
if no adhesion exists. Designing a lateral
reinstatement that is pressure tight is
crucial. Knowing if the liner will adhere to
the host pipe long term is also important.
In gravity lines, estimating the liner
service life is accomplished by using
flexural creep calculations. In pressure
lines, tensile creep will be used to define
service life. Creep analysis considers the
deterioration of tensile properties over time
and under stress. After 10,000 hours of
actual data, a regression line is plotted
through the data points. the formula for
the regression line is used to extrapolate
a data point at 50 years. that ‘long-term’
value will be used in the design calculations
to construct the liner.
While the CIPP process is not new, use
of this process is relatively new. As raw
materials become available to provide the
needed properties, and as contractors
develop the process to install, CIPP liners
used to successfully renovate pressure
pipelines is no longer a ‘thing of the future’.

minutes with Gerda hald
Trenchless International introduces you to the members of the ISTT Executive Sub-Committee. Here we
speak to Gerda Hald from the Scandinavian Society for Trenchless Technology, who has been helping
the industry develop for over 25 years.
how did you first become involved
in the trenchless industry?
During my engineering study, I worked for
a short period of time for a contractor on a
pipe bursting job. I gained an insight into a
very progressive industry and already at that
time, 25 years ago, I hoped to be a part of
that development.
Which organisation are you from
and how long have you been on
the executive Sub-Committee?
I am working for VCs Denmark, the third
largest water and wastewater company
in Denmark. We operate six waterworks,
14 wastewater treatment plants and
3,400 km of water and wastewater pipeline
network. I am responsible for planning and
investments, and as a part of that the use
of no-dig technologies for both rehabilitation
and installation of new pipes.
In 2001, I was elected for the first time
to the scandinavian society for trenchless
technology (sstt) board and I became a
member of the Danish workgroup, and in
2010 I was elected chairman of sstt. My
involvement in sstt led to an interest in the
Istt and I joined the EsC in 2008. At the
board meeting in Berlin 2011 I was elected
for my second period on the EsC.
What has been the most
memorable project you worked on?
I have worked on a lot of memorable
projects over the years, and tried many
no-dig methods for both drinking, waste
and rain water pipes. I have worked with
many imaginative and creative contractors,
and together we have solved a wide variety
of problems.
A very memorable project for me was
my involvement in establishing the Danish
Quality Control schemes. the scheme is an
impartial and voluntary system established
by the No-Dig Group (part of the Danish
Construction Association) after years of
pressure from some of the largest Danish
municipalities. I was Chairman of the Control
Committee for the Control scheme when it
was founded in 1997; I was one of the three
members representing the users.
What do you see as the most
important role and/or
responsibility of the ISTT?
the most important role of the Istt is to
be known worldwide as the society where
you can find, learn and discuss all matters
concerning trenchless technology. the
Istt has a responsibility to all the Affiliated
societies, especially in helping ensure a
fruitful co-operation and assist in providing
information and knowledge concerning
no–dig technologies.
how do industry initiatives such
as conferences and publications
help you in promoting Trenchless
Technology in your country?
Istt and sstt conferences make
it possible to be informed about new
knowledge, to discuss current issues,
and learn from others’ experiences.
Conferences, workshops and the
magazines help to spread knowledge about
possibilities and experiences.
What are some of the main
challenges your country is facing
with Trenchless Technology and
how do you think these can be
overcome?
I believe that trenchless technology is
well known and used in the scandinavian
countries. Yet there still remains a potential
to expand the use of the technology. I think
that the need for us to be mush more aware
of the carbon footprint of the work carried
out will be a vital factor for the use, and
for extending the use, of no-dig methods.
the challenge we face now is to be able
to prove the actual footprint and then
take the carbon footprint into account in a
reasonable way.
The most important role of the ISTT is to be known worldwide as the society where you can find,
learn and discuss all matters concerning Trenchless Technology.

About Istt/Membership
the Istt is the umbrella organisation for trenchless technologists in over
30 countries of the world. In 30 countries, groups of trenchless technologists
have their own national groups that are affiliated, while the remainder are
registered directly with the Istt.
trenchless technology covers the repair, maintenance, upgrade and new
installation of underground utility services using equipment and techniques
which avoid or considerably reduce the need for excavation. the Istt promotes
research, training and the more extensive use of trenchless technology through
publications, co-operation with other NGOs, an annual international conference
and an interactive website.
trenchless technology is recognised as an environmentally sustainable
technology and is particularly suited for use in densely populated urban areas
by reducing disruption to people’s daily lives, social costs (traffic congestion,
damage to road surfaces and buildings, air quality), noise and dust. trenchless
technologies also have a considerably reduced carbon footprint compared to
trenching in most situations.
