What to do when an inspector calls

What do you need to know about regulators such as the Environment Agency and

HSE?

Regulators such as the EA, HSE and Local Authority are key stakeholders for many eight2O activities and we are

regularly required to engage with them on various issues Including obtaining advice, licences and permits.

Visits with any regulator may be pre-arranged but these regulators are also warranted officers and so if they arrive

on site we are obliged to grant them access. If they deem necessary they can stop work, carry out interviews under

caution, take samples and even issue on the spot fines.

If a visit and evidence leads to them suspecting wrong doing this may lead to further investigation and potential for

further legal action.

What should you do if an inspector attends

your site?

• Ensure that you see a copy of the regulator’s ID and note

down the individuals name.

• Prior to escorting the individual on site, ensure that they

have the necessary PPE, have signed in on the visitor’s

book and have had the necessary visitor’s induction.

• Whilst walking around site ensure that you take photos

of the same areas as the inspector.

• Take notes of who spoke to the inspector and an outline

of the discussion.

• If they take samples, for example of discharged water,

ensure that the site take a duplicate sample at the

same time. This will ensure that we are able to send the

sample off for independent testing.

• If documents are requested and taken please ensure

copies are available or taken prior to them leaving site.

• If documents or samples are collected, the site should

be given a chain of custody to sign. This chain of custody

states that the sample was witnessed being taken by the

inspector at a specified location.

• Ensure that one member of the team, usually the Site

or Project Manager, exchanges contact details with the

inspector and becomes the single point of contact for

any future communication. This will enable the team to

build a relationship with the inspector and keep them

informed of any required remedial actions that are

being undertaken.

• DO NOT ask how much money we will be charged for

their time

• DO NOT question the inspector’s suspicions and

conclusions without good evidence.

Wellbeing Be Mindful Campaign -

Focus on Suicide

This week we focus on suicide as part of the Wellbeing Be Mindful Campaign.

Suicide can be a taboo topic in society but we are encouraging staff to openly

discuss their own experiences of suicide.

In 2014, 6,122 suicides were registered in the UK. Most people have thought of

suicide from time to time and not all people who die by suicide have mental

health problems at the time of death. However, many people who kill themselves

do suffer with their mental health, typically to a serious degree.

Understanding suicide

Suicide is described as an act of intentionally ending your life, many people who

have had suicidal thoughts say they were so overwhelmed by negative feelings

they felt they had no other option. However, with support and treatment people

are able to allow the negative feelings to pass.

There’s no single reason why someone may try to take their own life, sometimes

suicide can occur without warning and the sad reality is that, no matter

what, some people will succumb to suicide but thankfully many suicides are

preventable.

In the courts

Water Company Subsidiary fined £26,000 for odour

A business innovation subsidiary of a UK water company have been heavily fined following odour

complaints about a composting plant in Lanarkshire.

The site had permission to turn waste into compost, but the bad smells were in breach of that

permission. The compost plant was outdoors and the turning, screening and maturation of the compost

contributed to the bad smell.

The equipment designed to treat odours was also not performing properly. Despite the good intentions

for innovation and recycling, those living near the plant were “regularly and severely impacted” by the

odours. All such plants are expected to use the best available techniques for preventing or, where that is

not practicable, for reducing odour.

Get Support!

If you are concerned about suicidal thoughts or are worried about someone’s

wellbeing, you can contact the Samaritans at any time. They will help sort

through feelings, talk through options and help find a way forward. You can also

find local support in your area to help make sure you can access care and support

where you need it, when you need it.

Incident - Chalk/Calcium Carbonate

Discharge to a Non-Main River

What happened?

• A recent incident on an eight2O

site saw chalky water discharged

into a non-main river (usually

a dry ditch) situated parallel to

the site. The site had set up the

dewatering system three weeks

previously, had a permit to pump

formalising their monitoring

regime and had undertaken the

activity without any problems

until the morning of the incident.

• Following a complaint received

downstream of the site, the

discharge point was checked and

cloudy water was observed being

released into the environment.

At this point all pumping and

dewatering activities were

immediately stopped.

Why did it happen?

There are 2 potential reasons for

the incident which may have acted

individually or in combination:

• The blinding activity undertaken

on the day of the incident may

have impacted on the alkalinity

of the water in the vicinity of the

shaft. A change in alkalinity can

turn water containing calcium

carbonate cloudy. This water was

then drawn up by the dewatering

sump and into the silt trap.

• A change to a more chalk like

ground strata meant that the

equipment being used was

no longer appropriate for the

dewatering activity.

What were the potential

consequences of this

incident?

Water contaminated with suspended

solids such as chalk can be extremely

damaging if allowed to enter

watercourses. Damage can include:-

• Blocking fish gills leading to

death

• Deoxygenating water killing any

reliant organism

• Smothering aquatic plants

• Transport of toxins into an

ecosystem

• Alteration of a rivers chemistry

e.g. pH which can have an impact

on certain species

• Water pollution events such

as this account for many

prosecutions under the Water

Resources Act each year and can

result in unlimited fines and even

prison sentences. Prosecutions

can also have a significant impact

on the reputation of our business

and can also impact on future

work winning.

What can we do to prevent it from happening again?

• Where dewatering to surface water, a watercourse precondition checklist must be completed and the site

must ensure that the wider environment is assessed within this (i.e. flowrates of the watercourse prior to

discharge, water quality samples from both up and downstream and photographs of all monitoring locations)

• All dewatering operations must be fully risk assessed using the necessary templates

• Ensure that the site has established what water and potential sediment will need to be monitored in terms of

quantity, quality etc.

• Changes in the environment , including a variation of ground strata, should lead to a reassessment of the risk

• Dewatering operations require the use of the eight2O Permit to Pump process to be followed.

• Dewatering and pumping operations must be appropriately monitored with records kept including

photographic evidence of all samples taken.

• IEMP control plans must be site specific to the activity being undertaken and identify water management

equipment specification, monitoring and maintenance requirements etc.. Relevant activity specific

information such as monitoring should also be included within the RAMS.

• When dewatering to surface water, monitoring must be undertaken at locations downstream as well as at the

initial discharge point.

In the spotlight

Tunnel Inspections - Walthamstow

Overview

In early November the team mobilised in Walthamstow

fishery’s to undertake various tunnel inspections.

The first was tunnel was only a few hundred meters long

and was in good order with next to no mussel or silt inside.

Following on from this a compound was set up in the

Lockwood compound opposite the main fisheries, to allow

for works to the second tunnel , which spanned 6km to

begin. Shortly after the spine tunnel was started which

runs from the break pressure tank just south of the William

Girling Reservoir to Coppermills Water Treatment Works.

Preparing for the tunnel cleaning

Once the permits were acquired by eight20 from Thames

Water, the survey was undertaken. With all the lift plans,

isolation procedure and RAMS in places.

Firstly a floating pontoon was set up with a frame, block

and tackle attached allowing them to pick up the isolation

plates and float them into position, once they had been

lifted into the water using a 25t city crane.

The isolation plates consisted of three C section plates

and a cover lid. Each C section is approx. 1mtr high and

2.0mtrs long. These are all bolted together with gaskets

between every section, along the head wall and then

studded to the base. Once the isolation plates were in

the water, specialist divers were bought in to survey the

shafts. Each section was installed until completed and the

process repeated at two locations shaft A & C.

Once all the isolation plates were installed, the tunnel was

isolated and the instruction was given to drain down the

tunnel. To do this a permits to pump was raised and the

pumping was monitored until the tunnel was empty.

Tunnel Cleaning & Inspection

Once the tunnel was drained, the survey phase of the

works could begin. It was at this stage that the amount of

mussels/ silt within the tunnel was apparent.

The survey started at shaft A where the tunnel was almost

completely full with only 300mm gap to crown. It was

because of this that the survey was abandoned at shaft

A and attempted at shaft C where debris depths of 8 to

900mm were found and so the survey was deemed unsafe

to continue until the waste had been removed.

DISAB suction units were then employed to extract the

mussels and silt waste. This involved connecting 6”hoses

down the shaft and working from the main riding basket

at the pit bottom to clear the way into the tunnel.

Ventilation fans were also installed to purge the tunnel

along with specialist ammonia gas detectors.

Barhale continued to extract waste and clear the tunnel

for a number of weeks by extending the hose into the

tunnel. However due to the amount of build-up, trollies

and bins were also used as a much faster way to move the

material.

Once the tunnel was completely cleaned it was then

inspected by Thames Water and eight20.

What’s been happening across eight 2

O

1. Digging up our past at

Axford

Archaeologists working on the

Axford pipeline project have been

discovering new information

about our past around current-day

Swindon.

Evidence of our Roman ancestors

re-using their chalk quarries as pits

to burn their rubbish in have been

discovered at a number of locations

along the new pipeline route. The

quarry pit below was discovered

south of the M4 and was adjacent

to a Roman roadside settlement.

(The darker areas show evidence of

burning.)

More evidence of Roman life has

been found in the area of the buried

Roman town of Durocornovium.

Fine pottery vessels and five Roman

Denarii (silver coins) dating from 2nd

century AD highlight the wealth of

people living in the area during these

times.

2. Sharing knowledge

between Utilities

A fantastic demonstration of best

practice sharing and collaboration

between contracts, eight2O, tRIIO

(joint venture for National Grid) and

SQS (a tRIIO recycled aggregates

supplier), occured this month.

Members of the construction, design

and procurement teams from both

SMBJV and CABVJV attended a

recent event to showcase recycled

aggregates; increasing awareness of

the production techniques, technical

applications and ways to ensure a

final quality product.

Chris Stones, from SQS, talked

through the process from when the

waste aggregate is received at the

site through to sorting, screening

and finally production of the recycled

aggregates, including Type 1, pea

shingle and eco surround.

The SQS team also demonstrated

how recycled aggregates are used

for reinstatement across all of

their tRIIO contracts. Backfilling a

specially prepared excavation they

demonstrated how the material is

tampered down and compacted

and how this compaction is tested

aggregates on their contract.

Mark Guinn, Strata Highways,

detailed the testing that is carried

out on the recycled aggregates

produced at SQS and on the

stability and compaction of

the material once it has been

placed in the ground. Mark

also explained the possible cost

savings available if recycled

aggregates are used.

The day provided great learnings

and experience that can be used

on eight2O to increase the usage

of recycled aggregates across our

contracts.

The earliest (and most worn –

on the far left) is a rare silver

Denarius struck in Gaul or Spain

for the Emperor Vitellius in AD

69. The remaining four coins are

all minted for the Emperor Trajan

(AD98 – 117)

Prehistoric grain storage pits of,

likely Bronze Age or /Iron Age

(c.2000BC – 43BC) have also

been found close to an Iron

Age enclosure below Badbury

Hillfort. This enclosure may have

3. CDM Training

Last month 28 HSE inspectors visited

Mogden STW as part of an in-house

training course on CDM. The inspectors,

either new to HSE or Construction

Division, attended a day long workshop

that looked at the practical application

of the regulations from the viewpoint

of the Client, Principle Designer and

Principle Contractor. The day also

included presentations on CBS and

various forms of contract.

4. Success at the NJUG Utility Awards at the Houses of

Parliament- Sustainable Methods & Materials Award!

Last month saw eight2O (Utilities and Civils Thames Water Contract) walk away with a top

prize from the Houses of Parliament – the NJUG Award for Sustainable Methods and Materials.

Going up against Morrison Utility Services and the Kelly Group, the eight2O team scooped the

accolade for achieving sustainable construction.

The award was won due to eight2O’s street works team’s dedication to using several sustainable

methods during design and construction – including hydraulic modelling and BIM, nonintrusive

surveying techniques, trench sharing with other utility works, vacuum excavation and

paperless works management systems. This covered works including Pressure Management,

Mains Replacement, AMP4 Rollover, Motcomb Street and Blythe Road.

Two other eight2o projects were also runners up; Swiss Cottage Trunk Main Replacement for

their work at minimising disruption and Hatton Garden for their work at keeping the public fully

informed.

Congratulations to

all those involved in

winning this prestigious

NJUG Award!

Community Engagement Project

Ashton Keynes Primary School

Overview

Whilst installing a new plant

in the Cotswolds, an eight2o

site team wanted to give

something back to the local

area. Ashton Keynes Primary

School was local and so Barry

Airey (General Foreman) and

Jonathan New (Graduate

Civil Engineer) visited and

discovered they needed

support.

1.Enhancing a Memory

Garden

The school had a dedicated

area to a pupil who had

passed away. It had become

a bit of a reflective area for

the children, but was in a

sorry state.

The unwanted pampas grass

was swiftly removed, but to

truly redevelop the area a bit

more love and attention was

required. A solar powered

water feature was selected,

along with plants and

pebbles to smarten up the

area. The school now hope

to use this area to highlight

sustainable energy and so we

purchased a blackboard and

recycled plastic benches for

them.

The site team are also

engaging with the pupils

via educational assembly’s

to talk about sustainable

energy and to help the pupils

find out about recycling and

material reuse.

2.Bug Hotel & Bird Houses

The school take part in

‘forest schools sessions’ and

are working to complete

an Eco-award. This involves

running weekly outdoor

activities as part of their

curriculum, as a method

of learning about the

environment. As part the of

this they asked if eight2O

would be able to a deliver

an environmental related

activity.

From this, Ali Thomas

(Environmental Advisor) led

an activity to build a bug hotel

with a group of pupils. With

the help of the site teams and

her van driver Dave Wass, a

range of site materials were

collected, including pallets,

bricks, pipes, old wellies,

redundant lifting straps and

cardboard. Even breathalysing

tubes from eight2O inductions

were sterilised and reused.

Additionally pupils bought in

recycled materials from home

including twigs, fir cones, milk

bottles and plant pots. Even old

wellies were transformed into

luxury recycled bird houses that

were hung on trees located near

to the bug hotel.

Adding to this, a short talk on

garden wildlife owing to the

presence of pipistrelle bats

and great crested newts on the

school grounds was given and

the pupils asked on who they

thought would live in a house

like this…
