HammersmithPumping Station
Currently, untreated sewage regularly overows into the River Thames from Londons Victorian sewerage systemvia combined sewer overows (CSOs). The proposed Thames Tunnel would intercept these overows through theuse of a new storage and transfer tunnel, which would link west London and Abbey Mills Pumping Station. Thesewage ow would then be transferred to Beckton Sewage Treatment Works via the Lee Tunnel. The reductionin untreated sewage entering the River Thames would bring long-term benets for the environment and users ofthe River Thames. In order to deliver the project we need a number of sites along the route and this documentidenties our current preferred site at Hammersmith Pumping Station.

Section 1: Introduction and site informationWe are proposing to use part of a currently vacant site
known as Hammersmith Embankment/Fulham Reach atthe corner of Chancellors Road and Distillery Road for
this construction work and to accommodate permanent
structures required to operate the main tunnel. The site
would be used to connect the existing local CSO, known
as the Hammersmith Pumping Station CSO, to the main
tunnel.
The location of the site is shown in Figure 1A. The site
includes our existing pumping station, located to thesouth of Chancellors Road together with part of the
Hammersmith Embankment/Fulham Reach development
site. The remainder of the Hammersmith Embankment/
Fulham Reach development site is located to the south
and west. Beyond Distillery Road, which is to the east
of the site, is Frank Banfield Park. Along Chancellors
Road, to the north and west of our site, are residential
properties and offices. The site is within the Fulham ReachConservation Area.
This site information paper sets out our proposals at
Hammersmith Pumping Station. We have also produced
project information papers, which cover overarching
topics relating to the project. Where we consider that a
project information paper is particularly relevant, we have
highlighted this in a related documents box. At the end
of this site information paper is a list of other documents,which may be of interest and a glossary of terms.

How we chose this siteCSO
What we proposed at phase one consultation
Through our site selection process, we identified three
possible shortlisted sites to intercept the Hammersmith
Pumping Station CSO. At phase one consultation, which
was held between September 2010 and January 2011, wepresented these sites:
Foreshore, adjacent to Chancellors Wharf
Frank Banfield Park
Hammersmith Pumping Station.
Hammersmith Pumping Station was identified as our
preferred site to intercept the Hammersmith Pumping
Station CSO at phase one consultation.
Why we have amended our proposals
Since January 2011, we have considered the comments
received at phase one consultation, feedback from
ongoing engagement and new information; and
undertaken further technical work. This has resulted in us
re-assessing potential sites to intercept the HammersmithPumping Station CSO.

What we are proposing at phase two consultation
We have identified five shortlisted sites to intercept the
CSO, as shown in Figure 1B. These are:Foreshore, adjacent to Chancellors Wharf (site 1)
Frank Banfield Park (site 2)
Adjacent to Hammersmith Pumping Station,
Chancellors Road (site 3)
Thames Water Depot and Pumping Station,
Chancellors Road (site 4)
Hammersmith Pumping Station (our preferred site).
Hammersmith Pumping Station is our preferred siteto intercept the Hammersmith Pumping Station CSO.
This is because it is a brownfield site with good access
and the construction works could be coordinated with
the proposed mixed use development at Hammersmith
Embankment/Fulham Reach. The shaft is located further
away from existing residential dwellings than would be
the case in the other shortlisted sites. The site is alsosmaller than the site presented at phase one consultation
(since we only need a site to intercept the CSO).
Site 1 Foreshore, adjacent to Chancellors Wharfisa shortlisted site which is considered to be less suitable
than our preferred site because vehicular access from
the public highway network is severely limited and
construction activities would have more effects on the
local area and the River Thames.
Site 2 Frank Banfield Park is a shortlisted site whichis considered to be less suitable than our preferred site
because the use of site would result in the loss of public
open space.
Site 3 Adjacent to Hammersmith Pumping Station,Chancellors Road is a shortlisted site which is considered
to be less suitable than our preferred site because thedrop shaft location would limit the potential for future
development of this brownfield site.
Site 4 Thames Water Depot and Pumping Station,
Chancellors Road is a shortlisted site which is consideredto be less suitable than our preferred site becauselocating the drop shaft in the depot would have greater
potential effects on the adjacent residential properties.
Depending on the site layout when intercepting the
CSO, we would need to undertake some of the works in
Chancellors Road, which would mean closing the road for
between nine to eighteen months.
Main tunnel and long connection tunnel
What we proposed at phase one consultation
Through our site selection process, we identified that a
main tunnel reception site and long connection tunnel
drive site was required in the Hammersmith Bridge area.
We identified two shortlisted sites and presented these
at phase one consultation, which was held betweenSeptember 2010 and January 2011.
The sites were:
St Pauls School Playing Fields
Hammersmith Pumping Station
Hammersmith Pumping Station was identified as our
preferred site at phase one consultation.
Why we have amended our proposals
Since January 2011, we have considered the comments
from phase one consultation, feedback from ongoing
engagement and new information; and undertaken
further technical work. This work led us to review possible
sites within the western end of the main tunnel and our
tunnelling strategy, which considers how sites might belinked together to construct the main tunnel.

Since phase one consultation, a new planning application
for mixed use development has been submitted,
which covers the area around the Hammersmith
Pumping Station site. If planning permission isgranted, construction could start in the near future.
The development proposals mean that there would be
insufficient space to accommodate a main tunnel site
at the Hammersmith Pumping Station site. Therefore,
we needed to find an alternative site to receive the main
tunnel.
Our review of our tunnelling strategy concluded that the
long connection tunnel, which would link flows from ActonStorm Tanks to the main tunnel, needs to be a similar
diameter to the main tunnel. Therefore we propose to
extend the main tunnel to Acton Storm Tanks to enable
direct connection of the CSO to the main tunnel. This
means that a main tunnel site is no longer required at
Hammersmith Pumping Station.

Section 2: Construction
Construction activitiesConstruction activities are required to intercept the
CSO. We would construct an interception chamber to
intercept the CSO. A connection culvert would link the
interception chamber to a drop shaft (approximately
33m deep) through which flows would pass down to
a short connection tunnel. This would then join to the
main tunnel. Figure 2A illustrates the below ground
infrastructure proposed. These activities would take
place within the area indicated by the red line in Figure
1A, in five main phases, lasting approximately three
years in total. The main construction activities at this
site are set out in Table 2.1.

Site layout and construction phasesFigures 2C and 2D show how the site might be laid out
during the construction phases, which are set out in Table2.1 and Figure 2B. These layouts have been informed by
the size of the infrastructure proposed, the construction
methods required and the location of neighbouring
buildings and structures. They have also been developed
to minimise effects on the local community and
environment. Particular factors at this site that have
influenced the layout are as follows:
We have arranged the site offices so that they would bepositioned along the northern boundary of the site to
act as a screen from the construction activities for the
residents on Chancellors Road.
Effects of construction works on adjacent land uses
have been minimised by siting as much of the works
as possible within the existing Hammersmith Pumping
Station site.
Access to the site has been located so that it could beshared with the neighbouring developer.

Additional works and activitiesThe main construction activities at this site are set out in
Table 2.1. We would also need to undertake additionalworks and activities, some of which may be located
outside of the area indicated by the red line in Figure 1A.
The anticipated additional works and activities are set
out in Table 2.2.
When Type of works What we would do
Required for
constructionphase
Installation of equipment to monitorenvironmental matters such as noise,
vibration and dust.
The locations of monitoring equipment would be agreed
with the local authority and relevant landowners.
Protection works to third party structures
(such as buildings, bridges and tunnels).
We would undertake studies to identify any effects our
construction work may have on third party structures.
The studies may recommend particular construction
methods or, in very limited instances, protection works.
Diversion of utilities. Utility diversions may need to be carried out outside ofthe site boundary.
Temporary connection to utilities (such as
water, sewer, phone and electricity supply).
If we are unable to make a connection to utilities within
the site, we would need to make a connection in either
Chancellors Road or Distillery Road.
Traffic management works.
These may need to extend beyond our site and could
include relocating kerb lines, repainting road lines and
modifying traffic signals.
Required for
operational
phase
Permanent connection to utilities (such as
water, phone and electricity supply) for the
operational tunnel.
We expect to connect to utilities from within the site.

Construction transport and accessWe would transport materials to and from the site by
road. We have considered the use of the River Thamesto transport materials to and from this site. However the
planned Hammersmith Embankment/ Fulham Reach
development, which is likely to be in place when we start
construction, would make river transport from this site
impractical. Table 2.3 sets out the anticipated average
daily number of lorries visiting (ie travelling to and from)
the site during the peak months of each phase.
Construction traffic would access the site fromthe Hammersmith Flyover (A4), travelling around
Hammersmith roundabout, down Fulham Palace Road
(A219) and Chancellors Road, and turning into the site
from a new entrance on Distillery Road. Traffic would
leave the site via the same route. This access route is
shown on Figure 2E. Beyond this, construction traffic
would use the major road network to get to and from its
final destination.
We may need to suspend or relocate some on-street
parking bays along Chancellors Road during construction.There would be minor footpath diversions around the
site, as shown on Figures 2C and 2D. Based on our current
design, we do not anticipate that any road diversions, bus
stop relocations or junction changes would be required.

Management of construction worksOur construction works would be managed in accordance
with an agreed Code of construction practice (CoCP).For phase two consultation, we have produced a draft
CoCP Part A: General requirements, informed by CoCPsfrom other major construction projects in London and
consultation with the local authorities. Through the
environmental impact assessment process, scheme
wide principles to address potential effects on the local
environment have been identified and integrated into
the design. The CoCP Part A sets out scheme wide control
measures that would be used to minimise potentialeffects during the construction process.
Table 2.4 sets out what we consider to be the key issues
for this site during construction, and how we are currently
proposing to address them.

Issue Our response
Possible effect on the early
commencement of the plannedHammersmith Embankment/Fulham
Reach mixed use development
by St George PLC on the vacant
Hammersmith Embankment site
adjacent to the pumping station.
We have worked with the developer to agree a programme of works
that would facilitate both the construction of the tunnel and phased
commencement of their development.
Potential loss of and damage to trees
near the corner of Chancellors Roadand Distillery Road.
Only a small number of trees would need to be removed in this location.
We are in discussions with the developer of the proposed Hammersmith
Embankment/Fulham Reach development regarding their plans for this part
of the site, which would include any replacement planting, if necessary.
Possible effect of construction vehicles
on the volume of traffic on Chancellors
Road and Distillery Road, with
associated effects on local residents
trying to access Frank Banfield Park.
We have sought to minimise disruption to the local road network through
our site layout and design. We would manage the effects of road transport
through our traffic management plans, which will seek to limit the number
of vehicle movements and hours of operation, identify the most suitable site
access points and any necessary highway management arrangements.
Possible effect of noise and vibration on
neighbouring areas.
The contractor would be required to implement noise and vibration control
measures at the worksite, which will be set out in the CoCP. Continuous
tunnelling would only be undertaken for a short period of time to construct a
connection tunnel from the drop shaft to the main tunnel.
Possible effects on local air quality and
dust nuisance in neighbouring areas.
Preliminary findings indicate that while there is the potential for dust
nuisance effects, there are unlikely to be any significant local air quality
effects at any of the sites. The contractor would put in place air and dust
control measures at the worksite, which will be set out in the CoCP.

Section 3: Future use
This section describes the site after the completion of the
construction work, ie when the main tunnel is in use the
operational phase.
Design
Since phase one consultation, we have progressed the
design for the permanent use and appearance of the
structures at Hammersmith Pumping Station. The design
of the permanent proposals follows our scheme-wideprinciples and takes into account comments made
and ongoing engagement with the London Borough
of Hammersmith and Fulham and other technical
consultees.
Our permanent works need to incorporate functional
elements, which are required for the operation of the
tunnel. These include:
Underground structures with ground level access covers
including: a CSO drop shaft with an internal diameter
of approximately 11m, connection tunnel to the main
tunnel, connection culvert, interception chamber, valve
chamber and a passive filter chamber.
A ventilation structure up to 6m high.
Maintenance vehicle access.
Table 3.1 sets out the site specific issues that have
influenced our permanent design proposals and how we
have addressed them in our proposed design.

Issue Our response
Effects on surrounding
residents and proposed new
properties of the planned
Fulham Reach residential
development.
The permanent works have been designed in conjunction with the new mixed use
development proposed at the Hammersmith Embankment/Fulham Reach site to
ensure the designs are complementary.
The arrangement of the permanent works means that they would either be located
underground, within the existing pumping station site or within new public areas,
thereby minimising the effect on existing and future residential properties.
Existing site utilities.The permanent works have been designed to minimise the effect and any risk of
disruption to existing utilities along Chancellors Road.

Operation and maintenanceOnce the tunnel is operational, we would need access
to the site occasionally for inspection and maintenance
purposes. We expect to visit the site approximately
once every three to six months to carry out inspections
and maintenance of the ventilation and below ground
equipment. This is likely to involve a visit by staff in a
small van, and may take several hours.
Once every ten years, we expect to carry out a major
internal inspection of the tunnel and underground
structures. This is likely to involve a small team of
inspection staff, a small team of support crew and two
mobile cranes to lower the team into the shaft. This is
likely to take several days and would require temporary
fencing around the shaft for safety and security while the
inspection takes place.
We may also need to make visits to the site for unplanned
maintenance or repairs, for example, if there is a blockage
or equipment failure. This may require the use of mobile
cranes and vans.
Access would be from within the pumping station
compound on Chancellors Road, or from Distillery Road.
Management of operational effectsWe have undertaken technical work, including stakeholder
engagement, to assess and identify the key issues
associated with this site once it is operational. Table
3.2 summarises these issues and how we are currently
proposing to address them.

Issue Our response
Possible odour effects during
the operation of the tunnel.
Odour effects at this site are expected to be negligible because we have developedanAir management plan to minimise possible odour and air quality effects arisingfrom the operation of the tunnel. The technology we are proposing to use at this site
includes the use of passive below ground carbon filters that will remove possible odour
before air leaves the ventilation equipment.
Disturbance from future
maintenance access.
Permanent access would be required for maintenance and servicing purposes to the
shaft and ventilation equipment. Any planned maintenance visits would be undertaken
during normal working hours and all visits managed to avoid disruption to local
residents, businesses and users of affected public areas as far as possible.
