Dear readers,
We are delighted to be able to present you with a new issue of
our corporate magazine inFORM – published specially and exclusively
for customers, employees and friends of our business
in cast iron pipe and piles.
Work on the aspects of our restructuring covered by company
law have now been completed. Together with their sales and
marketing companies Buderus Litinové Systémy s.r.o. (Czech
Republic) and Buderus Pipe Systems FZCO (United Arab Emirates),
Buderus Giesserei Wetzlar GmbH (BGW) and Tiroler
Röhren- und Metallwerke AG (TRM) now form an independent
group of companies. We are glad to see the business developing
in this way, because we can now concentrate our forces on
the cast iron pipe business and devote all our efforts to our core
business and its customers.
In this issue, we report as usual on current projects, events and
people in our group of companies.
This time we have made a special feature of our activities in the
field of piled foundations using ductile piles. In the first half of the
year we have already worked with our customers to carry out a
number of very interesting projects, such as the new Grimming-
Therme thermal spa in Bad Mitterndorf in Austria and the Solar
Energy Park at Lebrija in Andalusia. You will find reports on these
projects on pages ten and eleven.
Other high spots of the first half of the year were the many international
fairs and exhibitions. The Alpitec exhibition in Bozen
and the SAM in Grenoble were this year‘s most significant exhibitions
in the market for Alpine snow-making facilities. They
were followed by national exhibitions in Saragossa (Spain), Brno
(Czech Republic), Bydgoszcz (Poland) and in the Russian capital
Moscow. The industry‘s main event was of course the IFAT,
which took place in early May in Munich, and you will find a detailed
report on this on the pages below. The high point of the
year‘s conferences and exhibitions in 008 will be the World Water
Congress of the International Water Association, which will
be held from the 7th to the 1 th of September in Vienna. For
the first time for years, this congress is going to be returning to
the German-speaking part of the world. May we take this opportunity
of extending to all of you a cordial invitation to attend
this event, which is highly esteemed in the industry.
We regret to say that we are increasingly concerned about worldwide
developments on the raw materials and procurement markets.
The effects of the international boom in demand in the construction
and steel industries are now making themselves felt in
our business too. For example, just in the months from March
to June this year, the purchase price of our main raw material,
scrap iron, went up by more than 00 Euros per ton – a rise, the
like of which has never before been seen on the raw materials
market. Regrettably, the price of coke too is moving upwards at
the moment in a similar headlong fashion. With products such as
cast iron pipes and ductile piles which use large amounts of mate-
rial, developments like these have a major impact on the cost of
the product. It is virtually impossible to compensate for them by
making savings elsewhere. This is why we are finding ourselves
compelled to pass on the major part of these price rises to our
customers. As from 1 June 008, we have had to introduce surcharges
for the price of scrap in almost all areas of the business
to enable the situation to be dealt with in a reasonable way. It is
clear to us that this will make it considerably more difficult for
fairly long-term projects to be costed. However, the action we
have taken here is simply a reflection of the general trends in
the prices of raw materials and we therefore trust that our customers,
and the clients for whom they are working, will understand
why we have had to do this. At the same time, we hope
that the situation will soon settle down, because this will be in
the interests of everybody in the industry. Demand in the foundation
and underground construction industry still seems to be
strong. Both for ourselves and you, dear readers, we hope that
this state of affairs will continue.
In this issue, we would like to continue a story we began to tell
in the past and to introduce you to some of our company‘s important
partners in the field of marketing. From its base near
Manchester, the HamBaker Group deals with our cast iron pipe
business in Britain. HamBaker is totally committed to our highquality
products and is making major efforts to promote sales of,
for example, our thrust-locked BLS ® /VRS-T pipe in a marketing
environment which is not always easy. You can find our portrait
of the company on page 14.
See too the profiles of new, young and promising employees who
work for our group of companies (page 1). With their talents
and abilities they represent the future of our company. We think
you should get to know as many of them as possible.
We hope you will enjoy reading the magazine and would like to
wish you all the best for the forthcoming holiday period and that
you will have a pleasant and relaxing holiday.
We‘ll be back with you with the next issue of inFORM in November
008.
Until then, with best regards, we are

2,560 exhibitors: up 15%
120,000 visitors: up 10%
Foreign participation rises
by a third
Those were the results that once again
demonstrated the significance of IFAT, the
15th International Trade Fair for Water,
Sewage, Refuse and Recycling, held from
the 5th to the 9th of May at the New
Munich Trade Fair Centre, as the world‘s
largest and most important trade fair for
environmental technologies and environmental
services.
There were a total of ,560 exhibitors
from 44 countries showing innovative
products and services in the fields of water,
sewage, refuse and recycling. That figure is
more than 15% up on the figure for IFAT
005. Among the exhibitors, the IFAT Fair
showed a high international participation
of a good third. The marked international
orientation was also reflected in the programme
for the IFAT conference which,
as well as talks by specialists and symposia,
also included Country Specials for Spain,
Eastern Europe, Russia, the Arab regions,
India, China and Japan.
Buderus and TRM set out their stall in Munich
on a 00 square metre stand worthy
of the companies and their products. „The
future is ductile“ was the slogan under
which the cast iron pipe group took the
stage to show what it had: superb products
and good prospects. To learn more,
we interviewed Ulrich Päßler, CEO of
BGW and a member of the executive
board of TRM.
Editor: Herr Päßler, the slogan at IFAT
was „The future is ductile“. Did the success
of the cast iron pipe group at the fair
do anything to demonstrate the truth of
this slogan?
Ulrich Päßler: The answer to that question
is a very definitive „Yes“. More than
ever before, our ductile cast iron pipe for
drinking water supply and sewage disposal
aroused the interest of trade visitors to
the Fair. There were many conversations
in which we found that ductile cast iron
is considered to be the material of the
future because it will carry high loads, is
flexible in how it can be laid, is reliable and
is very long-lived. In today‘s world, these
properties are coming to be increasingly
valuable. „Sustainability“ is the key word
that has become the guiding principle for
many public companies and local public
enterprises.
Editor: It was not just at the IFAT itself
that there was a considerably higher international
participation among both exhibitors
and visitors; on the Buderus stand too
things were more international than ever
before. What is your view of this?
Ulrich Päßler: This is a very welcome
development and is a result of the fact that
BGW and TRM have now moved well beyond
their home markets, and have done
so with great success. The opening out
into European markets and into the world

market has shown that with our products,
and above all the VRS/BLS ® system, we
are well able to meet fresh challenges.
This is why there were delegations from
all parts of Europe, the Near East and Asia
that we welcomed to the stand and why
there were many promising prospects
that we were able to discuss.
Editor: Is the way things went at this
year‘s IFAT proof that the changes in the
cast iron pipe group have had a beneficial
effect?
Ulrich Päßler: Most definitely. There has
been an improvement in our international
sales and marketing structure and we are
focussing on high-grade problem solvers
in the form of our restrained socket joints
and the CMC coating and this has set in
train successes not just at the IFAT but generally.
Last year we were still able to chalk
up a two-digit rise in turnover and there
is every prospect of this trend continuing
in 008. The Russian market is growing
fast, and given that this is another market
where we want to continue establishing
our presence, it is true to say that we are
on the right road and that the slogan for
IFAT 008 was more than justified.
Editor: The next big events for the industry
are the „World Water Congress“
(WWC) in September 008 in Vienna and
„Wasser Berlin“ in 009 and people are
already looking ahead to these. Are they
some more events at which the cast iron
pipe group is going to be represented?
Ulrich Päßler: Yes, the preparations are
already being made and I do not see that
there is going to be any need for us to
change our slogan.

A c l e a r d e c i s i o n i n f a v o u r
o f d u c t i l e c a s t i r o n
Cast iron veins to carry some of the lifeblood of Berlin-Brandenburg International Airport
For what is currently Germany‘s biggest
transport project, Buderus Giesserei
Wetzlar GmbH is supplying a large part of
the drinking water and sewage systems
for the internal development of the airport
site. There will be 4 kilometres of
cast iron pipe for drinking water and sewage
of nominal sizes from DN 80 to DN
400. Some 60% of these pipe have to be
laid this year and the rest are to follow in
009.
How did the company come to land such
a large and important order?
It was some years ago that the preparatory
work began at the engineering consultants.
In the end, the customer and
the engineering consultants made a very
clear decision in favour of ductile cast iron
as a material. They appreciated the well
known advantages which the material and
the related systems have but there was
more to it than that. They also valued the
good experience there had been with the
construction and operation of large-scale
airport projects in the past, such as Frankfurt
am Main airport for example. Early
in 007, the invitations to tender were
sent out to interested construction companies
all over Europe. As well as being
highly qualified and adequately financed
over the construction period, these companies
also had to draw up a plan of costs
for the project. This was where Buderus
too had to work out prices following comprehensive
costings made in consultation
with its suppliers and had to provide technical
assistance. Then, late in 007, after
extensive re-negotiations, the contract for
this immense construction project, which
covered not only drinking water and sewage
but also other media, was awarded to
a well-known Berlin consortium consisting
of the Karl Weiss construction companies
and the Beton- und Rohrbau company.
Because February 008 was the date set
for construction to begin, regardless of
the weather, negotiations had to be conducted
quickly and conscientiously. For
demanding projects, high-grade products
which are manufactured and looked after
by committed and able employees are a
prerequisite.
Because of the scale of the project, employees
of BGW‘s Applications Engineering
Division and the marketing department
all sat round the same table with the construction
companies in the consortium
right from the start. All these people knew
one another from the many demanding
construction projects they had worked on
in the past and were already convinced of
their partners‘ ability to deliver.
As well as the quality of the product systems
and the flexibility matched to the customer‘s
requirements, what is also particularly
important is logistics and everything
to do with it. Deliveries have to be notified
to BBI by e-mail and have to arrive
punctually within a time slot. For customers
of BGW, it goes without saying that the
field sales force (Lutz Rau, Berlin Sales Division)
will be there to see to their needs
and that if any special questions arise relating
for example to the BLS ® system or
to the unlocking with SIT/Plus then employees
of BGW‘s Applications Engineering
Division will be available to give onsite
instructions. This long-term trust on
the part of customers is the very thing that
Buderus has always worked to develop,

even when prices have to be competitive
and margins are tight. After several rounds
of negotiations, it was BGW that the consortium
finally opted for to be given the
contract for the internal development of
BBI international airport. Following this,
the Karl Weiss company visited BGW in
Wetzlar and satisfied itself that the production
department would perform to the
requisite standard and that the workforce
at the Wetzlar production plant had the
The demands of the future have already
been met: since September 2006, development
work has been underway at the
airport at Schönefeld to turn it into the
new Hauptstadt-Airport BBI (BBI Capital
Airport, a possible alternative name for
BBI). As from 2011, all flights in the Berlin-Brandenburg
region will be concentrated
on this new airport in the southeast
of the city. The airports in the city
centre at Tegel and Tempelhof will be
closed down in parallel.
The design of BBI envisages a modern
airport where distances are short and for
this reason the terminal is situated between
the two takeoff and landing runways,
which are laid out in parallel with
one another. BBI will be one of the new
generation of airports: low-cost, functional,
and cosmopolitan with modernday
industrialised architecture. At BBI,
the region of the German capital will be
able to provide business travellers, tourists
and companies with an airport offer-
right sort of friendly competence.
To safeguard the smooth running of this
important international hub and interchange
point for air travel, it is essential
for it to have a supply system of high quality
and one that can also be expanded to
meet future demands. For this, the customer
and the construction companies are
putting their trust in the ductile cast iron
pipe systems from Wetzlar.
BBI Airport – the new airport for Berlin and Brandenburg
ing excellent connections that handles international
flights, that has its own motorway
junction and that has a railway
station immediately below the terminal.
BBI is fully capable of handling A-380s:
the runways and taxiways will allow even
modern-day jumbos to take off and land
at it.
A takeoff capacity of 22 to 25 million
passengers is planned for 2011. If the
development in passenger traffic demands,
the airport can be developed to
handle up to 40 million passengers. BBI
thus gives the Berlin-Brandenburg region
the capacities it will need in the next few
decades.
A springboard to the east
The outlook is clear: The BBI will become
an airport in the centre of Europe whose
primary focus is point-to-point flights within
Europe and selected long-haul flights.
The airports of Berlin have traditionally
focussed their attention very much on
Eastern Europe. With the expansion
of the EU to the east,
this tendency has become
even more marked. Added
to this there is the strategic
advantage of being
well placed in the centre of
Europe: flight times to Eastern
Europe and Asia are an hour
shorter that they are from established
hub and interchange
airports in the west of continent.
To Berlin in next to no time
With the airport shuttle, the time to travel
into the centre of Berlin will be just 20
minutes and by motorway it will be just
on 30 minutes. BBI will make Berlin the
European capital whose international airport
is the shortest distance away.
BBI Airport City
As well as the attractive flights that will be
available, there will also be an extensive
non-aviation offering at BBI. The plans
are for the businesses and restaurants in
the airport itself, just in front of the terminal,
to be supplemented by the airport‘s
own shopping and office complex – BBI
Airport City. Here there will be businesses,
cafés, bars, restaurants, hotels and
conference centres for passengers and
visitors to the airport.

Waterpower plays an important part in
the generation of energy in South Tyrol.
It is a renewable and inexhaustible source
of energy and using it safeguards the energy
supply and at the same time protects
our habitat for future generations.
The environmental balance sheet for waterpower
is the best of all, because the
water from rivers is used and is returned
to them unchanged. Small hydroelectric
generator stations are particularly good
because not only are they an economical
energy source that is kind to the environment
but they also have beneficial effects
on the habitat of both man and beast.
Turbine pipe including a large number of special structures
“Manhole“ – produced in the form of a DN 600/600 all-flanged tee
s t a t i o n a t W i n n e b a c h
i n S o u t h T y r o l
This is why the largest energy supplier in
South Tyrol, SEL AG, has again invested in
a new small hydroelectric generator station.
The station, which is being built in
the Pustertal in South Tyrol to the most
stringent ecological standards, is to have
an average annual rated output of 1,170
kilowatts. It is permissible for 60 to 480
litres per second of water to be diverted
from the river Winnebach to generate
power. The remaining volume of water
flowing has been measured as 50 litres per
second in winter and 100 litres per second
from April to November. Pipes measuring
a total of , 00 metres in length are being
laid for the generator station. The project
envisages the construction of a water-diverting
generator station with a water intake
structure situated at Ast in the commune
of Terenten. The water is diverted
by an underground pipe constructed from
individual pipes of ductile cast iron. The
turbine building, most of which is above
ground, is situated in the parish of Dörfl
in the commune of Vintl, where the Winnebach
flows into the river Rienz. Having
been used in the turbine, the water is returned
to the Winnebach by a concrete
channel followed by an overflow weir.
Trench holding the feed water pipe and the empty
piping for control cables

So that the landscape is spoiled as little as
possible, the whole of the pressure pipe
has been constructed as a DN 600 underground
pipeline (of wall thickness classes
K9 and K10). The turbine building is being
partly buried in earth bankings.
Nor have the fish been forgotten: so that
there is no risk to their spawning grounds,
a so-called fish ladder has been incorporated
in the water intake structure. What
is more, small hydroelectric stations have
a beneficial effect on fish stocks anyway,
because the eddies from the turbines introduce
oxygen into the water.
The special feature of this project is the
many inspection and connection „manholes“
distributed along the length of the
. kilometre long path followed by the
pipe carrying the feed water. Four inspection
openings (or „manholes“, in the
form of DN 600/600 all-flanged tees) have
been installed to provide access facilities
to the pipe every 600 meters for inspection
work. However, the pipe carrying the
feed water supplies water not only to the
turbine but also to two branch pipes running
to hydrants, which are to be used for
fighting forest fires. There are also four
nearby farms whose sprinkler systems
are being connected to the new pressure
pipe.
For the most part, the route followed by
the pipe is along forest roads and through
areas of forest but there are also two high
points where it crosses the Winnebach.
To avoid any air inclusions in the pipe, it is
necessary for an automatic air supply and
air venting unit to be installed.
Because of the many special structures,
the Winnebach hydroelectric generator
station project involves more fittings than
any other turbine project for the past ten
years – about 110 fittings are being installed.
Another novel feature is the system for
locating leaks by means of fibre optics. To
enable possible leaks to be located as accurately
as possible, a fibre optic cable has
been laid below the bottom of the pipe.
This technique has been developed by
the University of Hydraulic Engineering
at Innsbruck.
(We will be publishing a report on this subject
in the next issue of inFORM.)
Mountains, castles and sundials
The Pustertal in South Tyrol:
a paradise for nature-lovers and
culture-seekers
The Pustertal is a valley whose height
ranges from 700 to approximately
1,600 metres. It is situated mainly in
South Tyrol and it runs between Brixen
and Lienz. It branches off eastwards
from the Eisacktal at a point to the north
of Brixen and the rivers Rienz and Drau
flow through it. In the High Pustertal,
there are the characteristic peaks of
the Sexten and Lienz Dolomites. This
is also the place where the celebrated
Drei Zinnen tower into the sky. Deodat
de Dolomieu was the first man to investigate
the calcareous rocks in the region,
and it is from him that these peaks
take their name. The Dolomites have a
close connection with the history of alpine
mountaineering. A name that will
be remembered in this connection is the
film director and actor Luis Trenker, who
came from the Tyrol and whose films often
„starred“ mountain landscapes.
The Pustertal has some 73,000 inhabitants
living on a good 2,000 square kilometres
of land. The best known towns
are Bruneck, Wengen and Toblach.
From the administrative point of view
it consists of the districts of Hochabtei,
Hochpustertal, Kronplatz and Tauferer
Ahrntal.
A wide range of sporting activities are
available: climbing, hiking, mountainbiking,
paragliding, rafting and much
else besides. In winter, the High Pustertal
is an absolute paradise for skiers.
A special attraction is the micro-climate
tunnel at Prettau. This is a disused mine
gallery in which there are micro-climatic
conditions consisting of a temperature
of about 9° Celsius and a relative
humidity of approximately 95%. These
have a beneficial effect particularly on
people suffering from respiratory prob-
lems. In the Pustertal tourists will find
everything they want from luxury hotels
to family-owned boarding houses. The
charm of the valley comes from the association
of the old and the new, of traditional
country life and modern-day living,
of the Tyrolean and the Italian.
Seeing the well-preserved town walls
and town gates and the castle at Bruneck,
the visitor will find himself transported
into the middle ages. Nowhere
else in Europe are there so many properties
dating from the middle ages situated
so closely together as there are
here. With its 400 or so castles and citadels,
South Tyrol generally is the region
which can boast the largest number of
medieval edifices. There are many romances
from the age of chivalry that
tell the story of those times. Rodeneck
Castle is one of the largest castles in
South Tyrol and is the home of a renowned
cycle of frescoes dating from
the 13th century showing scenes from
Hartmann von Aue‘s Middle High German
epic „Iwein“. The „Gustav Mahler
Music Weeks“ would also seem to
be a byword among lovers of classical
music. Today, handicrafts are still a living
presence in the Pustertal in the form
of its wood-carving, its lace-making, its
weaving and its making of Patschen or
felt shoes. Typical culinary products are
cheese and home-cured bacon.
A special event is the Stegener Market
which is held in autumn every year and is
the biggest food and handicraft market
in the whole of Tyrol. There are booths
there selling mulled wine and the special
little sausages and stalls where you
can buy schnapps and cheeses and all
sorts of handicraft products.
That the people in the Pustertal seem
to have a rather sunny disposition is
shown by one of the other special features
of the region: the many sundials.
What is it that people say? Only count
the happy hours!

O n f i r m f o u n d a t i o n s
A site measuring 40,000 square metres,
those words alone are enough to give
some idea of how big the project is – Nestling
between the mountains of the Ausseerland
area in Austria‘s Salzkammergut,
the Grimming-Therme thermal spa and its
hotel resort are being built in Bad Mitterndorf.
The project is intended to continue
the development of the region and to be
a driver of year-round tourism. The hot
springs at Bad Mitterndorf, which were
known even in Roman times, will help to
ensure that even greater use is made of
existing tourist attractions such as the
Tauplitz and Loser area for Alpine and
cross-country skiing.
When the ground was broken for this 50
million Euro project in December 007, it
marked a change to the overtaking lane
for the tourist industry in the Salzkammergut.
From the 8,000 square metres of
land that the spa itself will occupy, future
guests and visitors will be able to enjoy the
view they will have of one of the most
impressive panoramas in the Steiermark:
mountains, interspersed with gently roll-
ing hill and knolls and enthroned above
them all the Grimming, the mountain that
personifies the Hinterbergertal, about
which there is such a rich tapestry of legends
and folk-tales. But before that can be
possible there is a lot to do.The whole site
had to be given deep foundations. For
combined environmental and economic
reasons and also in view of the minimal
settlement that is permitted, the decision
that was made in the case of this structurally
demanding building project was to use
the pile system made by TRM. Due to the
existing soil conditions (water table three
metres below the surface of the ground
and a confined aquifer at a depth of 5 to
The TRM pile system
The TRM pile system consists of centrifugally
cast pipe of ductile cast iron with
conical sockets and with spigot ends
which have a matching conical taper. As
a result, the individual lengths of pipe can
be assembled into longer units as the driving
progresses without the need for any
special tools. Due to the rigid joints, they
then form a load-bearing member which
is one continuous unit – the pile A driven
pile is sunk into the soil – by driving – and
then dissipates, or transmits, forces from
the structures situated above it into the
soil. In actual fact, this procedure is a very
old one; in the Neolithic period and the
Bronze Age, piles for constructing dwellings
were already being driven into the
shores of bodies of water or directly into
the bodies of water themselves; this is
how the structures known as lake dwellings
were built.
The piles are made of ductile cast iron,
and this is a very elastic material which is
able to withstand tremendous mechanical
stresses – such as occur in the driving operation.
At a standard length of 5 m, they
Grimming-Therme thermal spa in Bad Mitterndorf – on deep foundations driven with TRM piles
7 metres), the work can only be done if
the springs are kept running or on other
words the deep foundations have to act
to some degree as an additional safeguard
against uplift. That each pile will have the
exterior load-bearing capacity laid down
is demonstrated by the driving criterion
when the pile is being driven. The piles are
pressure-grouted and, in the boggy ground
involved, this rules out any possibility of
the groundwater mixing with polluted
surface water. Hence, the TRM piles have
once again shown themselves to be an efficient,
fast and inexpensive deep foundation
system. If all the piles which have
been delivered to the sites were laid end
to end, they would cover a total distance
of 0 kilometres! Collaboration with the
construction company handling the contract,
Grund-Pfahl und Sonderbau GmbH,
has gone extremely well. The speedy
progress of the construction work and the
absence of any hold-ups (not a single pile
has fractured!) has been the result of good
logistics and of course of efficiency in the
driving operation.

are produced in two sizes (118 and 170
mm) and in different wall thicknesses to
suit the load transmission that is required.
The loads transmitted are between 50
and 140 tons. By plugging the separate
pipe making up the pile into one another,
piles of any desired overall length can
be obtained. The piles can take the form
either of ungrouted end-bearing piles or
of grouted piles which transmit loads by
skin friction. When a grouted pile is used,
liquid concrete (grout) is pumped into the
pile, the interior of which is hollow, at high
pressure during the driving operation and
escapes though an opening at the bottom.
The grout wraps itself round the outside
of the pile as the pile is being rammed
and forms an outer sheath of grout several
decimetres thick. In this way it increases
the surface area of the pile, thus generating
increased friction, and the grout hooks
its claws into the soil. An ordinary grout
pump is used for this pressure grouting.
Ungrouted end-bearing piles are filled
with concrete after they have been driven.
A pressure-distributing plate is mounted
on top of the fully driven pile and this gets
it ready to transmit loads
Near the Andalusian town of Lebrija on
the fruitful plain of the Guadalquivir, one of
Spain‘s biggest solar energy parks, which
will occupy an area of 0,000 square metres
and will produce an output of 6,500
MWh, is being built.
What was selected as the system used for
implementation was the „Mover“ system
developed by Solon Hilber Technologie
GmbH. These are finished modular units
for generating solar electricity which track
the sun as it moves. Because of this tracking
movement by the modules, it is possible
to obtain up to 40 % more electricity
than is the case with modules mounted
in a fixed position. The Mover stands on
a small pedestal and because of this the

The Lebrija solar energy park – TRM piles safeguard the foundation soil
ground below it can continue to be used
for other purposes, e.g. for raising cattle.
Also, because the large modular panels
move, there is no fear either of the
soil being eroded below the edges from
which rain drips off or of its drying out below
the movers. The structural design and
the control system of the Movers are such
that the panels will pivot to a position in
which their aerodynamics are good if the
wind speed rises to more than about 80
km/h and they will survive winds speeds
of up to 150 km/h without suffering any
damage. To stop any irregular settlement
of the solar panels and hence to prevent
any adverse effects on the pivoting mechanism,
the pedestals were designed to be
carried on pressure grouted TRM piles as
their foundations. Skin friction distributed
over the optimised length of the piles allows
the loads which occur to be transmitted
without any problems into the soft
soil present, as a result of which the use
of these piles forms the least expensive
way of obtaining a foundation. By the use
of lightweight equipment, any adverse effects
on the environment have been minimised
because of the small areas for access
and for doing the work which have
needed to be surfaced. Hence, to allow
an environment-friendly energy generating
system to be produced, what has also
been done is to install the deep foundation
which is kindest to the environment.

C u l t u r a l s p l e n d o u r s a n d a g r e a t q u a l i t y o f l i f e
„In Vienna everything was wonderful. Lots
of money and luxury galore.“ Despite what
he called the „Empress‘s sanctimoniousness“,
Giacomo Casanova certainly found
exactly what he liked in Vienna. Yet this
gossipy summing-up of the town that he
gives in his „Memoirs“ is still no more than a
snapshot from the 18th century. There other
conditions too that Vienna experienced.
He was not wrong though. As capital of the
Holy Roman Empire, and particularly under
the regency of the Habsburg emperor,
Vienna became one of the most important
cities in the world, and had an enormous
economic, political and especially cultural
influence. Above all in architecture and music,
for a long time it was Vienna that set the
style – one has only to think of names like
Haydn, Mozart, Johann Strauss the elder
and younger right through to Schönberg.
Innumerable concerts show that even today
Vienna is still one of the world‘s capitals
of music. As well as the music of the Vienna
classical period, the architectural and artistic
works of the Vienna Secession of the
years around 1900 are some of the enduring
witnesses of the city‘s more recent history.
With its .1 million inhabitants, Vienna
was the fourth largest city in the world at
that time. Today the number is about 1.6
million. For the ten million or so tourists
that the city welcomed in 007, it was impossible
to appreciate more than a fraction
of all these cultural achievements. Among
the most popular sights are the Stephans-
The cultural attractions of Vienna are overwhelming
dom (St. Stephen‘s Cathedral), the Schönbrunn
Palace and Zoo, the Kunsthistorisches
Museum, the Hofburg and of course the
Great Wheel on the Prater. The city centre,
with its magnificent buildings along the
Ringstrasse, is designated part of the world
cultural heritage.
What Vienna has a reputation for above
all is a high quality of life. There are many
easy-going coffee houses where one can sit
for hours with one‘s coffee with milk and
read the paper without being bothered by
the waiters. The Heurigen too – the bestknown
of these little wine-drinking locales
can be found in Grinzing − bear witness
to a more relaxed way of life. The Vien-
nese are also said to have an intimate acquaintanceship
with the transitory nature
of things. The author Milo Dor explained
it like this: „People just don‘t take themselves
too seriously here. Of course there
are people who try to play an important
role but everyone knows that it is just playacting.“
In no sense is Vienna just living off its past
splendours. The city is prospering both culturally
and economically. Vienna is the fifth
most wealthy region in the EU. Companies
see Vienna as a springboard to the East.
Particularly in anticipation of the eastward
expansion of the EU, many major foreign
companies made Vienna the hub of their
activities in the countries of central and
eastern Europe or founded a new centre
there to embark on their expansion into
these markets. There are many prestigious
international organisations that have their
headquarters in Vienna. With 147 international
conferences and congresses in 006,
Vienna was the world‘s favourite city for
events of this kind ahead of Paris and Singapore.
One well known conference is for example
the IWA World Water Conference,
which is being held there from the 8th to
the 1 th of September 008. It will be the
big questions of climate change, population
growth and the supply of water that will
be considered there. Tiroler Röhren- und
Metallwerke too will be present and showing
its commitment there (see the article
on page 1 ).

T h e i n t e r n a t i o n a l w a t e r i n d u s t r y i s m e e t i n g i n V i e n n a
World Water Congress and Exhibition, 7th to 12th of September 2008
The international water industry is making
a date with itself for September in Vienna.
The reason is the IWA World Water
Congress and its accompanying Exhibition.
The 008 World Water Congress in Vienna
continues a series of events that
have taken place in Paris ( 000), Berlin
( 001), Melbourne ( 00 ), Marrakech
( 004) und Beijing ( 006) and the series
will continue in Montreal in 010 and in
Busan in 01 .
What decided the choice of Vienna as
the venue for the IWA World Water
Congress in 008 was the wish to give
a prominent place on the programme to
the „Danube Region“, to possible new
countries joining the EU and, basically, to
„Eastern Europe“. The first indication of
this intention was the decision to put the
local organisation of the Congress into
the hands of the „International Association
of Water Supply Companies in the
Danube River Catchment Area“ (IAWD).
This body, together with IWA Conference
President Walter Kling, representing
the Vienna Waterworks, and the IWA
National Committee, will make sure that
there is an appropriate regional flavour to
the event in Vienna. The detailed organisation
of the programme is the responsibility
of the IWA Programme Committee,
on which there are prominent representatives
of the international world of water
professionals.
At the Exhibition, there will be around
00 stands and the ideal conditions offered
by the Austria Center Vienna will
allow attendees to fit these smoothly into
the Congress itself. Special exhibition areas
will be reserved for the most important
sponsors, who are taking part in the
event under a separate partnership.
Tiroler Röhren- und Metallwerke is one
of the so-called Gold Sponsors of the
event and will be showing on an appropriate
stand in the exhibition area.
The organisers are expecting more than
,000 interested professionals from the
water industry who, over the course of
the five-day event, will want to exchange
ideas and accounts of their experiences.
The Congress will offer a wide selection
of technical meetings, opportunities for
networking with business partners and
exciting ancillary events.
These will include for example a gala reception
at the Vienna Town Hall, where
the men and women attending the IWA
World Water Congress will be able to enjoy
an entertaining evening of music and
dancing ranging from the waltz to dancing
to midnight clubbing music.
Jointly with the conference organiser (the
IWA), the Council of European Munici-
Congress President Dr. Walter Kling
palities and Regions will be organising a
„Local Government Day“ as part of the
World Water Congress. The fact that this
is being held at the same time and place
is no accident, because one of the main
concerns for mayors in the European
part of the world is to deal with issues relating
to the subjects of water supply and
sewage disposal. At discussions and medleyed
events there will be an opportunity
to discover subjects and exchange information.
A particular highlight here will
be the talk that will be given to open the
„Local Government Day“ by mayor Dr.
Michael Häupl in his capacity as President
of the CEMR (Council of European Municipalities
and Regions).
On another evening there will be a private
concert by the Vienna Symphony
Orchestra in the celebrated Musikvereinssaal
exclusively for guests of the IWA.
Also waiting for the men and women attending
the conference will be a choice
range of lunches and evening meals and
of sightseeing tours and tour of places
of professional interest. Added to this of
course there will be the important technical
meetings at which the latest trends
and developments in the worldwide water
industry will be presented, ranging
from the design and operation of water
systems or the planning and provision
of water services through to measures
to combat the effects of climate change.
The latest and most innovative technologies
from all over the world and from the
Danube region will be shown at the exhibition.

DUCTILE IRON
„ O u r a i m s a r e t h e s a m e “
HamBaker – a sales and marketing partner who can be relied
on in Britain
HamBaker Pipelines is the Cast Iron Pipe
Group‘s sales and marketing partner in
Great Britain. A part of the HamBaker
group, the company was the outcome
of a merger between the Zyron company,
Buderus‘s former sales and marketing
partner in Britain, and the Olympic Pipeline
Products and Roban Ductile Welding
companies.
As Buderus‘s sales and marketing partner
and a producer of flanged pipe, Ham
Baker has the expertise and competencies
needed to supply customers with a
comprehensive range of ductile pipe and
accessories. Market conditions in Britain
have not been easy, but despite this Ham
Baker, under the leadership of managing
director Stew Bailie backed by his committed
team, has managed to double the
sales of Buderus pipe since the merger
in 005. Where the company is making a
particular effort is in the marketing of pipe
with BLS ® restrained joints.
Together with Buderus Giesserei Wetzlar
GmbH, HamBaker founded Buderus Pipe
Systems FZCO in Dubai in 007 and thus
strengthened the already well-established
contacts that existed in the Middle East.
Ed Howard, Ham Baker‘s Group Manag-
ing Director, has this to say: „Our company
is pleased to have an unusually good
business relationship with Buderus and to
have had this for quite some years now.
Our aims are the same as far as the quality
of our products is concerned and – something
that we consider particularly important
– service to our customers is our
number one concern, because we are only
satisfied when our customers are too.
The object of our common strategies is,
by our commitment and with the help of
the Buderus team, for us to continue the
increase in sales in Great Britain“.
As well as the company headquarters near
Manchester United‘s „Theatre of Dreams“
in Manchester, HamBaker Pipelines also
has a production site for flanged pipes at
Stoke-on Trent in the „Potteries“ – an area
of England which is world famous for
the production of china and porcelain.
Well known brand names such as Royal
Doulton, Spode, Wedgwood and Minton
had their home there. Although nowadays
there are also a number of modern factories
to be found in Stoke, the distinctive
feature of the townscape is still the old
„bottle kilns“.

SMAGuA 2008 in Zaragoza –
the technological shop-window for the
water industry
The 18th Smagua (International Water Exhibition) took place in
Zaragoza in Spain from the 11th to the 14th of March 008
When it closed its doors, the biggest trade fair in the field of
water technology on the Iberian peninsula could boast the best
figures in its history: 1,7 5 exhibitors and more than 5,000
trade visitors. These numbers underline the importance that
SMAGUA has in the European part of the world. At the same
time as the exhibition, preparations were also underway in
Zaragoza for EXPO 008, and it was under the general theme
of „Water and Sustainable Development“ that this exhibition
was opened to the public on the 14th of June.
In association with Construtec, Buderus Giesserei Wetzlar
GmbH exhibited a range of pipes specifically designed for
trenchless laying. Applications to snowmaking facilities were
also shown.
The large number of trade visitors who took an interest in
Buderus‘s BLS ® system and in the CMC pipe was a clear sign of
how special solutions are moving increasingly to the forefront
of people‘s attention. Construtec successfully completed the
snowmaking projects at Formigal and La Covatilla last year, so it
was no surprise that there should be a considerable increase in
the interest shown by skiing resorts in the Buderus solutions.
Generally speaking, the entire Spanish market is of interest at
the moment because the demand for more efficient up-to-date
water technology of the very best quality holds out the promise
of good opportunities for doing business over the next few
years and beyond. Long spells when there is little rain and increasing
water consumption triggered by an economy that is
growing well, combined with an unprecedented boom in building
in Spain, mean that large amounts of money are having to be
invested in water supply and sewage disposal.
Together with its Spanish partner Construtec, the Cast Iron Pipe
Group has long seen these signs of the times and, logically, has
established a good position for itself by showing at SMAGUA.
WETEX 2008
In the near future, the Gulf region is going to be faced with the
problem of increasing shortages of raw material resources and
will thus be compelled to adopt fresh approaches if it is to maintain
economic power and prosperity in its countries. Alternative
energy sources, environmental protection and the subject of
water will be of growing importance.
This being so, the WETEX exhibition, which was held for the
tenth time in succession at the Dubai International Convention
and Exhibition Centre from the 17th to the 19th of March, is an
important procurement platform for national and international
companies giving them, as it does, wide-ranging access to the
latest technologies and management solutions. The exhibition
provides representatives of the industry with an opportunity to
bring themselves right up to date on the subject of water, energy
and the environment in the Gulf region and, together with
their strategic partners, to set innovative solutions off on the
road to success. As it was last year, Buderus Pipe Systems was
among the exhibitors and concentrated on showing the CMC
pipe and the successful BLS ® joint.

Winter as an economic factor: SAM
ALPEXPO in Grenoble and ALPITEC in
Bozen
This year, the SAM, the International Exhibition of Mountain Regions
Planning and Development, was open to visitors for the
eighteenth time from the rd to the 5th of April in Grenoble.
BGW and TRM had decided that they would show at the SAM
for the first time. As they found when the exhibition closed its
doors, this was a wise decision. The exhibition confirmed its
position as an essential meeting point for professionals from all
over the world in the field of skiing resorts. This was clear from
the sharp rise in the number of visitors and foreign delegations
(15%), who came chiefly from Spain, Portugal, Italy, Switzerland
and the countries of Central and Eastern Europe, but also from
South America, Australia, China and Russia.
Among the factors contributing to the success of the exhibition
were the facts that the winter season from 007 to 008 had
been a very successful one and that „manufactured snow“ was
the very area where a strong demand could be expected for
facilities for making it. What counts in snowmaking is, above all,
the quality of the manufactured snow. Nowadays, there is hardly
a single skiing area one can think of that does not have snowmaking
facilities. The BGW/TRM stand was the biggest in the field of
„snow-pipes“ and it triggered feedback to match. Many planners
and operators of skiing resorts were able to satisfy themselves as
to the quality of the well presented product range and new and
important contacts were made. In a word: ductile pressure pipe
and their secure traction-resistant joints hit the spot.
The position was much the same when the „winter professionals“
got together in Bozen in the South Tyrol. Not long before
– from the 9th to the 11th of April – ALPITEC 008 had taken
place there. 1 4 exhibitors from 15 nations took the opportunity
to show their products and services to the almost 10,000
trade visitors on stands which were all very lavish. In the field of
snowmaking facilities TRM, showing its well-tried range of cast
iron pipe, had a strong presence as the only pipe manufacturer.
The response from visitors was very positive and showed that
ductile cast iron pipe have established an excellent position for
themselves in the skiing resort sector.

WOD-KAN 2008
WOD-KAN, the International Fair of Machines and Facilities for
Water Supply and Sewage Systems, took place from the 7th to
the 9th of May 008 in Bydgoszcz in Poland. BGW‘s sales and
marketing partner Tyco Waterworks Polska Sp. z o.o. presented
exhibits providing an overview of all the types of coating and
socket that can be supplied. This year, it was the open-air site
that had been selected for the company‘s attractive exhibition
stand. The stand, measuring about 50 square metres in size, was
constructed in the style of an Upper Silesian coalmine. Manfred
Hoffmann, head of export sales at BGW, was very happy with
the show put on at WOD-KAN: „It was not just WOD-KAN,
which is the most important fair of its kind in the central and eastern
European part of the world, which chalked up a rise in the
numbers of exhibitors and visitors; we too noted an increase in
interest among visitors belonging to the industry“.
It was time once again on the 0th of May. That was when VO-
DOVODY-KANALIZACE, the International Water Management
Exhibition, opened its doors in Brno in the Czech Republic, and
on the following two days more than 8500 trade visitors flooded
into the exhibition centre. The majority of foreign exhibitors
were from western industrialised countries, whereas the bulk
of the foreign trade visitors came from post-Soviet and near
eastern countries, from the Balkans and from North Africa, or
in other words from the countries that are still waiting for the
crucial investments to be made in water management, in the
infrastructure for water and sewage management and in environmental
protection. On an area of about 60 square metres,
BGC presented „a mini-IFAT“. The same exhibits as had already
stirred up lively interest in Munich did the same in Brno. They
were supplemented by the commercial range of fittings. Ivana
Drozdová, chief executive officer of BGC, was very positive in
the view she expressed of the company‘s showing: „Once again,
it has been seen that Brno is a centre for exhibitions where new
trading partnerships are born. We were able to make contacts
that promise to be successful and we were widely praised for our
first class presentation which, as we did at IFAT, we gave under
the slogan „The future is ductile“.

BLS ® and PuR TOP – the tailor-made solution to problems
Culverting of a canal between the Neuwieser and Partwitzer Lakes in the Lausitz
Between Berlin and Dresden, in the Lausitz, there is a landscape
that was produced by open cast mining and this is being changed
into a lake landscape that will extend into more than one of the
federal states. This will offer a long-term potential for creating a
special and attractive environment in which there will be a new
and close togetherness between home life, leisure and work. The
lakes, which are on three different levels, are being connected together
into a „lake chain“ by navigable canals.
As part of this work, the Neuwieser Lake (the lake left by the Bluno
mine) and the Partwitzer Lake (the lake left by the Skado mine)
are to be connected by a navigable canal in which there will be
a lock. In 00 , in line with the development aim for the Lausitz
lake chain, namely the conversion into a water-oriented tourist
region of more than purely regional significance, a connecting waterway
had already been created between what were termed
the „holes“ left by the Koschen and Skado mines. In 004, this
was followed by the building of a canal between the holes left by
the Koschen, Sedlitz and Skado mines. For the planned construction
of a canal between Bluno and Skado, the company responsible
for all the rehabilitation work, Lausitzer und Mitteldeutsche
Bergbau- und Verwaltungsgesellschaft mbH (LMBV), had to relay
a main drinking water supply pipe of DN 500 diameter belonging
to the Zweckverband Kamenz water supply company. So that
the pipe would be situated two metres below the canal, it had to
be laid at a depth of 15 metres. The floor of the culvert runs in a
protective tube of polymer concrete, which was connected below
water by divers working in a sheet-piling box. The DN 500
water-carrying pipe, running for a length of 180 metres, are fitted
with the well tried BLS ® restrained joints. Where the pipe had to
be laid in an area below the water table, a PUR TOP coating was
selected for them to allow for the very high pH of the ground
water. At the depth of 15 metres and given that the soil would
be loosened when the sheet piling boxes were withdrawn, stress
analysis indicated that a wall thickness well above standard – K14
in fact – would have to be used in the bottom region of the ascending
sides of the culvert. The fittings and the areas occupied
by the sockets were enclosed in addition in shrink-on material.
The PUR TOP coating, a development
of Tiroler Röhren- und
Metallwerke AG, means a polyurethane
coating of increased
thickness (4 0 µ), which is also
wrapped in an impact-resistant
tape. PUR TOP pipe are used
mainly in corrosive soils.
This was another special case
where the technical problems
could be quickly, safely and reliably
solved by the use of the
BLS ® restrained joint and PUR
TOP pipe of a special wall thickness
of K14. The company laying
the pipe was very happy with the smooth way in which the BLS ®
joints could be assembled even under the difficult conditions created
by the ascending sides of the culvert and the trenches leading
to the protective tubes. In the sections clear of the ground
water, normal epoxy-blue cast iron pipe and fittings of the new
generation equipped with BLS ® joints were laid.
The land can now rest by its lake shores
A new water-filled paradise in the Lausitz
A landscape is being given a face-lift. Where lignite had previously
been mined for some 160 years, a landscape of water
is now coming into being and this will change the character of
the Lausitz. In the region between Senftenberg, Spremberg and
Hoyerswerda, more than 2,000 million tons of lignite had been
open-cast mined from depths of up to 60 metres since the middle
of the 19th century. LMBV‘s last working open-cast mine in
the region, the Mero mine at Großäschern, became exhausted
in 1999. What were left were gigantic „holes“ which have been
filled with water to become lakes. The main object of transforming
the landscape in this way is to develop an unusual new landscape
whose character is formed by its bodies of water. At the
heart of the Lausitz lakeland will be a world of water comprising
ten lakes with a total surface area of 7,000 hectares connected
by navigable canals and locks.

The important thing was always water
An excursion during the sales force conference in April 2008 at Blankenburg am Harz
A report by ursula Mandler
The conference opened with Friedhelm Kleinblotekamp, head
of sales for Germany, introducing the new member of our field
sales force in the German Sales Department, Heinz-Jörg Weimer.
Ulrich Päßler, sales director, then provided an overview of
how the company‘s sales and turnover had been developing. A
point he stressed as particularly important was the way the price
of scrap had been shooting up, a development which, he said,
was making it necessary for the price of products to be adjusted
to match. This means that there are special demands on the field
sales force to explain why this has to be done and to make sure
that it can be done successfully.
To provide a little variety, there was a break in the process of
working though the many points on the agenda in the form of
an excursion to the Wienrode waterworks and the Wendefurth
dam. Our colleague Uwe Hoffmann, whose area covers the
Harz/Saxony-Anhalt region, was the man responsible for organising
this.
We first went to the Wienrode waterworks, which is situated
below the Rappbode dam and which is able to supply 180,000
cubic metres of drinking water a day. At the waterworks, we
were welcomed by Dipl.-Ing. Klaus-Peter Faber, head of pipe and
facilities maintenance for the Eastern Harz Supply Area. During
the guided tour, he explained the operations that have to be
performed if good drinking water is to be obtained.
The waterworks are supplied with water from the Rappbode
dam. Intake of the water is through two intake towers and the
depth of intake can be varied to six different levels. The water
reaches the Wienrode waterworks though a . kilometre long
tunnel. In the waterworks themselves, the soft water of the Harz
region is processed into drinking water by a process which is a
close copy of what happens in nature. The soft water from the
dam is cleaned and freed of algae and microscopic lifeforms by
48 open fast filter beds covering an area of , 00 square metres.
Carbon dioxide and limewater are used to harden the water
and stabilise its pH. The addition of small doses of chlorine and
chlorine dioxide ensures that the quality of the water remains
unchanged as it travels through the pipe system to the customer.
Via the Eastern Harz pipeline, the waterworks, which belong
to the Verband Fernwasserversorgung Elbaue-Ostharz supply
company, supply large areas of Saxony-Anhalt out as far as the
Halle region. The company supplies a total of some two million
people through a pipe network totalling around 750 kilometres
in length, which is fed by seven waterworks.
The second stop on our excursion was the Wendefurth dam.
This, when full, holds water with a surface area of 78 hectares
and has a reservoir capacity of 854 million cubic metres. The total
reservoir capacity is 9. million cubic metres.
The dam itself (which was under construction from 1957 to 1966)
is a 4 .5 metre high gravity dam which is in 16 segments. At the
valley floor it is 0 metres thick and at its crest it is still metres
thick. On the water face, the individual segments are sealed off
from one another by copper plates inset into the concrete. The
joints are also packed with tar and hemp to seal them. The bending
of the individual segments under the pressure of the water
is continuously monitored. The bending can be determined and
checked by means of pendulums suspended in the dam. Also continuously
monitored is the displacement of the segments relative
to one another. Running through the dam there are a number of
galleries for inspection purposes. On our guided tour, we were
able to go into one of these galleries and were able to see what
goes on inside the dam and what its monitoring equipment does.
The massive DN 000 annular-piston valves are able to discharge
up to 75 cubic metres of water a second. A study is being made at
the moment to see whether the constant outflow of water could
not be used to produce energy.
The rock in the area is manganiferous slate, which is not particularly
watertight. So that water pressure applied from below at
the foundation will not lift the dam, the load at the foundation is
At the entrance to the dam
relieved by more than 40 bell structures connected to riser pipes.
The water pressure which builds up is checked at spaced points.
There is an otherwise unused gallery which is used to study the
long-term behaviour of the mountain.
On the excursion, we were able to gain at first-hand a very impressive
picture of how rainwater is turned into drinking water.
Drinking water that reaches consumers over distances of many
kilometres through pipes made by us!
It was an interesting excursion and on our return to the conference
venue there was some discussion and consideration of what
had been seen.

TirolerBall
und Ball der Wiener Wasserwerke
The Wipptal region played host to Vienna – the Tyrolean Ball at Vienna Town Hall
On 6th January, the traditional Tyrolean
Ball took place in Vienna Town Hall. The
Ball is one of the highlights of the social
calendar and every year it is hosted by
a town or region in the Tyrol; this year
it was the Wipptal region that had the
honour. This was also why the prizes in
the tombola were holidays in the region.
The event is organised by Tyrolean Association
in Vienna.
The Ball was held in three rooms in the town hall: the Festivities
Hall, the City Council Hall and the Armorial Hall. There are incidentally
only a few very balls that are held in Vienna Town Hall.
The Mayor of Vienna always makes an exception in the case of
the Tyrolean Ball and gives special consent.
The occasion, certainly one of the most enjoyable in Vienna‘s
Fasching carnival season, was held under the honorary auspices
of Federal Minister Günther Platter, member of government of
his federal state Anton Steixner and the heads of government
of their federal states DDr. Herwig van Staa (the Tyrol) and Dr.
Michael Häupl (the state of Vienna).
After the official opening, which ended with the state anthem of
the Tyrol, the ,500 or more guests were able to take a turn on
L. to r.: Prok. Thomas Schleicher, TRM head of sales for Austria, DDr. Herwig van
Staa, head of government of the federal state of the Tyrol and Hi-Zin Pak (wife
of Ulrich Päßler, member of the executive board of TRM)
the dance-floor. There were some 600
people – associations of promoters and
wearers of traditional costumes, orchestras,
and companies of ceremonial guards
– whose activities were devoted to creating
the right festive setting for the Ball.
Tradition was the keynote of the occasion.
This has always been the case for
as long as there has been a Tyrolean Ball.
It was held for the first time in 19 0, though not in the town hall
but in the Sofiensaal.
It was a glittering occasion and many prominent figures from
politics and business were able to meet one another there. TRM
which, by the way, was also helping to fund the Vienna Waterworks
Ball on the 7th of March, had hired the Mayor‘s box and
therefore had a particularly splendid setting in which to extend
a personal welcome to more than 40 guests, mainly customers
and representatives of important organisations. Thomas Schleicher,
who was himself born in the Wipptal and is head of sales
for products for municipalities, said how satisfied he had been:
„The atmosphere was very good; there was a cordial reception
waiting for us in Vienna and our guests spent a wonderful
evening at the Ball.“

More people who are now working to make ductile cast iron pipe and piles a success
Christian Auer, Head of Quality Management at TRM
Christian Auer, born 1975, has been working for TRM since February 008. In April, he took
over as Head of Quality Management. He had previously worked for a number of years for the
Austrian Automobile and Touring Club (ÖAMTC) in the breakdown assistance department.
In parallel with his work there he attended the College of Mechanical Engineering and, having
gained his degree at the College, he moved to the quality management department of the
Swarovski company. He also completed a training course as a quality manager. What Christian
Auer wants to do at TRM is to work with all departments in continuing the development of
our quality management activities with the right customer and employee focus, and above all
to support and promote company-wide projects and ideas. A second principal area of activity
will be collaborating in the drawing up of European standards as part of the European standardisation
process. Christian Auer enjoys spending his leisure time on expedition trips.
Florian Häusler, member of the in-house sales team at BGW
Since August 007, Florian Häusler, born 1988, has strengthened the team at BGW‘s in-house sales
department. When he left school, he decided to take a training course in business administration. In
004 he found a suitable training position with what was then Buderus Guss GmbH in Wetzlar and after
successfully passing the final examinations he was taken onto the payroll by BGW.
He is now responsible for handling quotations and orders for the Berlin/Brandenburg sales region.
The 0-year-old‘s hobbies are football and swimming. In his home district of Schöffengrund, he plays
in the first team of the Oberwetz/Oberkleen sports association.
Stefan Sterr, Head of Special Products at TRM
Stefan Sterr, born 1967, has been Head of the Special Products Department at TRM since January 008.
Having studied mechanical engineering at the University of Munich, he began his professional career in
1995 with BMW AG in Munich. In 1997 he moved to Robert Bosch AG at Hallein near Salzburg and two
years later made a further move to the Tyrolean abrasives manufacturer Tyrolit. In his capacity as head
of the business area dealing with the automobile and gearbox industry and subsequently with the turbine
industry, he was responsible for launching new product lines and for opening up new markets.
In a local context, we have been very successful in the area of snowmaking facilities and one of Stefan
Sterr‘s new and crucial jobs will be to take this business beyond Europe by giving it the right unitary form
and to ensure that the appropriate strategies are in place for solid and sustained growth in this key area
of TRM/BGW‘s business.
Heinz-Jörg Weimer, member of the field sales force at BGW
Heinz-Jörg Weimer, born 196 , has been working since 1 April 008 as a member of the
field sales force for the Frankfurt sales office. He trained in business administration with
Buderus and then, after his time with the Federal Defence Forces, he joining the shipping
office at Solms as the person responsible for the forwarding of concrete pipe, separators
and ceiling panels. In 1988 Weimer moved to what was then the Sewage Treatment Division
where, as from 00 , he also assumed responsibility for the export business as head
of sales for the in-house sales force. When the division was sold, he transferred to the
cast iron pipe side of the business and, after a period spent in in-house sales to familiarise
himself with the business, is now devoting all his efforts to selling cast iron pipe in the
Frankfurt sales region. Heinz-Jörg Weimer is married and has two grown-up children and
spends some of his spare time on Nordic walking, skiing and playing football.

The „STOP SIGN“ scheme for employees‘
suggestions
Sometimes it‘s the little things ...
The solution was a separate cover
Scene of the action: the extraction system from the cupola furnace
in TRM‘s smelting plant – here, the top gas which is extracted
is cooled with water after passing
through the preliminary coarse separator.
The particles of dust carried along
in the flow of gas are wetted at the same
time. The dirty water is then separated
from the gas in the disintegrator – a rotor
which generates the suction required
for extraction – and is pumped into a
sludge tank. The nozzles on the disintegrator
always suffered wear at just one
point, namely at the covers that were
bolted onto them.
Slavko Zivanovic found it irritating that if
a cover became worn it was always the
entire nozzle that had to be replaced. He
therefore suggested that the cover should be produced as a
separate part, so that it would then be only this part that had to
be replaced. This produced a net annual saving of about 1,400
Euros. Slavko Zivanovic was awarded a prize of 140 Euros for
this „STOP sign“ suggestion.
An opening rather than bins
Now that pipes were being centrifugally cast, the founders at
TRM‘s foundry had lost their supply of bins for slag. What had
always been used in the past were the empty bins for the core
wash or blacking used in the core-making department. To have
suitable containers specially made would cost around 6,000 Euros.
But a good idea by Zvonko Kupresak, Bozo Markovic and Ahmet
Sahbaz made any such investment unnecessary. What they suggested
was that, instead of the bins, a opening pointing downward
should simply be made to the rear of the tipping unit, so
that the slag could drop straight into the slag hoppers situated
beneath it. Sections of scrap pipes could be used as infeed chutes.
This procedure also makes the work that has to be done considerably
simpler, because the slag hoppers can now be emptied
simply with a fork-lift truck. There repeatedly used to be small
fires when the full hoppers were emptied because of incandescent
slag that they contained. This was an effective and efficient
suggestion and for it the ingenious trio were given a prize of
600 Euros.
Dietmar Fischer (centre), Head of the Human
Resources Department, awards the prize to
Zvonko Kupresak, who was also representing
his two colleagues. On the right is Armin
Eberl, chairman of the works council
Employees busy making „STOP sign“ suggestions at BGW
Since the „STOP sign“ scheme began at BGW, Ludger Bellscheidt,
the company‘s Head of Quality Control, and Hans-
Günter Cromm, a fitter in the maintenance
department, have each
submitted eleven „STOP sign“ suggestions
and, in numerical terms,
are the current record-holders.
One of the suggestions that Ludger
Bellscheidt submitted related to
the processing of complaints in the
Applications Engineering Division.
When complaints were received,
they were entered there in a register
and reports were drawn up and
were distributed in the form of copies.
This process was outdated so, to improve it, Ludger Bellscheidt
developed an Excel form on which the complaints are
now entered and which also allows them to be placed in a listing
at the same time as the form is saved. By means of this Excel
application, it is also possible for an analysis to be performed automatically
by reference to a catalogue of faults, thus dispensing
with the need for time-consuming checklists for the assessment
of complaints. The development of this special Excel application
has made it possible to dispense with the expensive programming
that would otherwise have been needed. Bellscheidt
shared the prize for the suggestion with Stefan Hobohm, who
did a great deal of work in seeing to the introduction of the application
in the RV-A department.
It struck Hans-Günter Cromm that,
in the pipe-painting department,
the place where the valves of the
spray guns were kept, namely below
the cable-operated towing arrangement,
was not very good and
that they were exposed to heavy
fouling there. Consequently, there
were often failures of these sensitive
devices. The ingenious fitter
therefore suggested that the spray
guns be placed neatly in a cabinet,
that markings be applied to show
which valve belonged to which gun
and that the air lines be laid in a cable duct so that they would
be protected from fouling. This new layout saves time and the
system suffers fewer failures.
Incidentally, as from mid-way through the year there will be a
new co-ordinator, Doreen Wittkamp, who will be continuing
the development of the „STOP sign“ scheme at BGW.

A nice, but heavy, present: a ton of molten
iron for the Special Castings company
Buderus Spezialguss GmbH has invested seven million Euros to
ensure that it will be equal to the task of satisfying the growing
demand that the future will bring for steam and gas turbines and
wind powered generators. On the 10th of April, an inauguration
ceremony was held for the new testing and acceptance building,
the sand preparation system and the new casting pit. In view
of this important event (it is after all the biggest capital investment
the company had made since 1901), Buderus Giesserei
Wetzlar GmbH wanted to make a generous gesture. It donated
a ton of molten iron. It was a nice, but heavy, present so Ulrich
Päßler, CEO of BGW, handed it over to his opposite number at
BSG, Karlheinz Bangel, in a more portable form – a credit note.
Päßler stressed that the investment was a clear signal to the
Wetzlar site and wished the people at Special Castings every
success for the future.
Day of Action on the 30th of August
Following the great success that it was last year, BGW will be
organising a second Day of Action on the 0th of August – when
hopefully we shall have bright sunshine for it. After combined
activities to beautify our working environment, this Saturday
will once again be brought to an end by a good, solid meal for
all the „actioneers and actioneeresses“, which will be some reward
for their efforts.
Invitation to the Family Day on the 13th
of September
Jointly with BSG, BGW will be launching
its second Family Day on the 1 th
of September. In the same way as
last year, excellent entertainment
and food and drink will be provided.
Once again, lottery tickets will be on
sale with the chance to win attractive prizes, there will be guided
tours of the works and to round things off there will certain
other attractions for young and old. Mainly though, our Family
Day will be an opportunity for people to meet one another in
company with their friends and relatives, to have a chat and to
spend time together in a relaxed atmosphere.
