Currently, untreated sewage regularly overows into the River Thames from London’s 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 of
the 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 Dormay Street.

We are proposing to use land off Dormay Street for this
construction work and to accommodate permanentstructures required to operate the main tunnel. The site
would be used to connect the existing local CSO, known
as the Frogmore Storm Relief – Bell Lane Creek CSO, to
the main tunnel. We also need a worksite from which
to drive a long connection tunnel southwards to King
George’s Park and northwards to Carnwath Road Riverside
to connect the CSOs at Dormay Street and King George’s
Park to the main tunnel. The long connection tunnel is
known as the Frogmore connection tunnel.

The location of the site is shown in Figure 1A. The site
is within an industrial area, which includes part of theLondon Borough of Wandsworth’s maintenance depot,
with the rest of the depot located to the west, north
and south of the site. To the east is The Causeway. The
northern part of the site is only required during the
construction period and is separated from the main site,
where permanent structures would be located, by Bell
Lane Creek. The site is partially within the Wandsworth
Town Conservation Area.This site information paper sets out our proposals
at Dormay Street. 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 site
CSO
What we proposed at phase one consultation
At phase one consultation, which was held between
September 2010 and January 2011, Bell Lane Creek was
presented as our preferred site to intercept the Frogmore
Storm Relief – Bell Lane Creek CSO.
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 has resulted in us re-assessing
potential sites to intercept the Frogmore Storm Relief –
Bell Lane Creek CSO. A potential new site was identified in
Dormay Street and in May 2011, in conjunction with the
London Borough of Wandsworth, we purchased this site.
Given the identification of a new shortlisted site, in June
2011 we held drop-in sessions for the community around
the site to understand any local issues they may have,
should there be a site in this location. We reviewed all the
comments we received and took these into account as
part of the site selection process.
What we are proposing at phase two consultation
We have identified three shortlisted sites to intercept the
CSO, as shown in Figure 1B. The sites are:
•Bell Lane Creek (site 1)
•London Borough of Wandsworth Depot (site 2)
•Dormay Street (our preferred site).
Dormay Street is our preferred site to intercept the
Frogmore Storm Relief – Bell Lane Creek CSO because
this site would result in fewer effects on an existing
business operation than either of the shortlisted sites. It is
brownfield land with few constraints and we now own the
site together with the London Borough of Wandsworth.
Site 1 – Bell Lane Creek is considered less suitablethan our preferred site. This is primarily because there
is an existing business on the site, which employs
approximately 80 people. Use of this site would
potentially affect this business through relocation and
loss of employment.
Site 2 – London Borough of Wandsworth Depot is
considered less suitable than our preferred site due to
the effects construction activities would have on theoperational council depot site. It would be difficult to find
a suitable alternative location for this facility.

Frogmore connection tunnel
What we proposed at phase one consultationDue to the location of the Frogmore Storm Relief – Bell
Lane Creek CSO and Frogmore Storm Relief – Buckhold
Road CSO, the Frogmore connection tunnel is required to
transfer the flows from these CSOs to the main tunnel. At
phase one consultation, we proposed to directly connect
the Frogmore connection tunnel into the main tunnel.
Why we have amended our proposalsFollowing a review of our preferred sites, we have
re-assessed the sites from which we could drive the
Frogmore connection tunnel.
What we are proposing at phase two consultation
As a result of changes to our sites since phase one
consultation, we have looked at whether King George’sPark, Dormay Street or Carnwath Road Riverside would
be the most appropriate site to drive the Frogmore
connection tunnel. Our preferred site is Dormay Street
because it minimises the effect on King George’s Park and
reduces the duration of construction works at Carnwath
Road Riverside. We would drive the Frogmore connection
tunnel south to King George’s Park and north to Carnwath
Road Riverside from Dormay Street.

Section 2: Construction
Construction activitiesConstruction activities are required to intercept the
CSO and construct the Frogmore connection tunnel. To
intercept the CSO, we would construct an interception
chamber. A connection culvert would link the interception
chamber to a drop shaft (approximately 24m deep)
through which flows would pass into the Frogmore
connection tunnel, before connecting into the main
tunnel. To drive the Frogmore connection tunnel, we
would lower a tunnel boring machine into the dropshaft at Dormay Street and would drive the Frogmore
connection tunnel south to King George’s Park and north
to Carnwath Road Riverside.
Excavated material from the tunnel drive would be
removed from the drop shaft and taken off site. 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 associated with these phases 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:
•
Heavy construction vehicles would use a temporarybridge over Bell Lane Creek, minimising vehicle
movement along The Causeway which has weight
restrictions. This would keep the majority of vehicle
movements internal to the site.
• The layout of the construction site has been arranged
to reduce effects on the operation of the existing
council maintenance depot.

Additional works and activitiesThe main construction works 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
construction
phase
Installation of equipment to monitor
environmental 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 constructionmethods or, in very limited instances, protection works.
If protection works are required to the existing sewer,
we would access the sewer network through existing
manholes.
Temporary connection to utilities (such as
water, sewer, phone and electricity supply).
We expect to make a connection to utilities in Dormay
Street or from within the site.
Traffic management works.
These may need to extend beyond our site and could
include relocating kerb lines, repainting road lines and
modifying traffic signals.
Strengthening works.We anticipate that strengthening works to The
Causeway may be required.
Required for
operationalphase
Permanent connection to utilities (such as
water, phone and electricity supply) for theoperational tunnel. We expect to connect to utilities in Dormay Street.

Construction transport and accessWe would transport materials to and from the site
by road. We considered the use of the River Thamesto transport materials; however, Bell Lane Creek is
not suitable given its navigational constraints and
shallowness. 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 main site from
Armoury Way (A3) travelling along Dormay Street and
turning right into the site. Light vehicles would access thenorthern part of the site to the north of Bell Lane Creek
from a new entrance from The Causeway. Traffic would
leave the two site areas via the same routes. These access
routes are 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 parking bays
on The Causeway during construction. A minor temporaryreconfiguration of the junction between Dormay Street
and Armoury Way (A3) may be required to enable lorries
to negotiate the turn into Armoury Way (A3). Based
on our current design, we do not anticipate that any
footpath, road diversions or bus stop relocations 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 CoCPPart A: General requirements, informed by CoCPs from 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 potential effects during theconstruction 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
Construction activities would need totake place within the London Borough of
Wandsworth’s maintenance depot site.
We have agreed with the London Borough of Wandsworth to use thesite temporarily during construction.
Management of site access from The
Causeway, which has a weight limit.
Use of The Causeway would be minimised by the construction of a
temporary bridge over Bell Lane Creek, which would accommodate
heavy construction vehicle movements within the construction site.
Possible effect on the integrity of existingflood defences.
As part of the construction of the tunnel, we would strengthen and
stabilise existing flood defences. The temporary bridge over Bell LaneCreek would also be designed to maintain the continuity of the flood
defences.
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.
We need to undertake continuous tunnelling at this site for reasons of
safety, cost and programme.
Possible effects on local air quality and dust
nuisance in neighbouring areas.
Preliminary findings indicate that while there is the potential for dustnuisance 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.
The construction of temporary bridge
support structures in Bell Lane Creek to
facilitate construction activities may affect
habitats and wildlife in the Creek.
We would seek to reduce effects on habitats and wildlife in the Creek.
Ecological surveys of the River Thames and foreshore are being
undertaken to identify possible effects, and design alterations would be
incorporated where possible. The contractor would put in place various
control measures at the worksite to minimise these effects as far as
possible. These 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
The design of the permanent use and appearance of
the structures at Dormay Street follows our scheme-
wide principles and takes into account comments raised
during ongoing engagement with the London Borough of Wandsworth 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 12m, connection culvert, interception
chamber, valve chamber and a passive filter chamber.
•A main ventilation column up to 6m high incorporated
with an electrical and control kiosk.
•A small diameter ventilation column to the interception
chamber 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
Effect of permanent works
on residential amenity and
business properties.
Since phase one consultation, the site has been relocated to avoid effects on the
operation of any existing businesses. The new site is also set further away from existing
residential properties.
Effect on existing flood
defences.
The flood defence river wall would be strengthened and stabilised where structural
weaknesses are identified.
Effect of permanent works
on site operation of the
council maintenance depot.
The layout of the permanent works would not interfere with the council’s existing
operations and would accommodate the council’s proposed plans to expand the
maintenance depot to encompass the northern end of Dormay Street.

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.
Permanent vehicular access would be from
Dormay Street.
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 developed
an Air management plan to minimise possible odour and air quality effects arising
from 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. We expectthat our permanent works would be situated entirely within the London Borough of
Wandsworth’s secure depot.

Combined sewer A single sewer system that takes both rainwater and domestic and industrial wastewater.
Combined sewer
overflow (CSO)
A structure, or series of structures, that allows sewers to overflow into the river when they
are full as a result of increased rainfall. Without the overflows, the sewers would back up

to carry out works that are essential to the project.
Drop shaft
A vertical circular concrete structure, used to drop flows from the high level of the CSO to
the low level of the main tunnel. It would also be used to provide access to construct the
connection tunnels.
Foreshore Ground uncovered by the river when the tide is low.
Interception chamberA structure, built on an existing combined sewer, which diverts stormwater overflow into the
main tunnel.
