We need a work site to connect the local combined seweroverfow (CSO), known as Holloway Storm Relie, to themain tunnel o the proposed Thames Tunnel project.We are currently proposing to use a vacant area o land o Butcher Row or this construction work and to accommodatethe permanent structures required to operate the tunnel.

At present, the combined sewer overows alongthe River Thames discharge untreated sewagedirectly into the river. This occurs because London’smainly Victorian sewerage system, which wasdesigned to transport both wastewater (sewage)and storm water (rainall), is at or near capacity.

Some CSOs discharge untreated sewage into theRiver Thames on average more than once a weekand ater only 2mm o rainall. This situationis likely to become worse in the uture, due topopulation growth and increased urbanisation.

The discharge o untreated sewage into the RiverThames is harmul to the environment. It reducesriver water quality, harms the aquatic lie, causesunsightly litter and increases the risks to healthor users o the River Thames.

Starting in west London and broadly ollowing thepath o the River Thames through the centre o the capital, the Thames Tunnel would transer theows rom the most polluting CSOs to BecktonSewage Treatment Works in the east o the city.

The need or construction sitesWe need a signifcant number o sites in orderto construct the Thames Tunnel project. Large‘shat sites’ are required at certain points alongthe route to allow the construction o the maintunnel. Smaller ‘CSO sites’ are also required near

each o the most polluting CSOs to connect themto the main tunnel.

We have carried out a detailed site selectionprocess to identiy suitable sites or theconstruction o the main tunnel and connectiono the CSOs. For more inormation, see ourproject inormation paper Construction Sites.

This process has enabled us to identiy ourpreerred sites along the route required or theconstruction and operation o the main tunnel

and the connection o each o the CSOs.

Thames Tunnel



How we chose the preerred siteWe shortlisted three possible work sites, close towhere the Holloway Storm Relie discharges into theRiver Thames. We assessed the suitability o eachsite by taking into account engineering, planning,environment, property and community considerations.From this process we have identifed our preerredlocation as Butcher Row (see map above).

Shortlisted sites:

Site 1 – Foreshore, o Narrow Street and near junctionwith Spert Street

This site is situated entirely within the oreshore o the River Thames. The site is close to the residentialproperties located on the northern boundary,overlooking the oreshore. It also has very poor roadaccess and the complexities associated with creatinga site in the river.

Site 2 – St James’s Gardens, o Butcher Row andTunnel Approach

This site is an area o public open space, which issurrounded by homes and major roads. It has achildren’s play area at its eastern end and provideslocal pedestrian and cycle route connections. TheRoyal Foundation o St Katharine and a numbero three-storey properties, which ront BekesbourneStreet, are located immediately to the north.

Its use would result in the temporary loss o anarea o protected public open space, including aplayground, in an area where there is a defciencyo open space and acilities o this type. There arealso a large number o mature trees, some o whichmight need removing to allow the construction worksto take place and which could harm the York SquareConservation Area setting. The shape o the sitewould also restrict the work site area.

Preerred site at Butcher Row – showing use during construction

Our preerred site:Butcher Row

We have identifed the area o land o ButcherRow as our preerred location because it is vacant,has good access to the road network and allowsor an efcient site layout due to the shape o thesite. It is also close to the sewer that we need tointercept. The majority o the construction workscan be located towards the northern edge o thesite, towards the DLR/railway line and away rom

The Royal Foundation o St Katharine and Chapel(a charitable conerence and retreat centre).

It also has a number o advantages when comparedto the two other possible locations identifed. Inparticular, it is vacant brownfeld land, and wouldinvolve less disruption to local residents and publicopen space.

Use o the preerred site during constructionWe would need to use the site as a constructionsite or approximately two years. It would then bevacated as much as possible but a smaller area keptsecure or subsequent equipment installation. Theplan above shows how we propose to use the siteto connect the CSO to the tunnel. It also shows theamount o space we think we would need to carryout the construction works but as the design o theThames Tunnel develops urther this could change.

Specifc measures may be necessary to reduce theenvironmental eects o construction and we wouldwelcome your views on the issues we should considerwhen developing our proposals. We will be presentingour more detailed proposals in our second roundo consultation beore the submission o planningapplications.

We propose that construction trafc would enterand leave the site using the existing entrance o Butcher Row.

Permanent use o the siteWe are likely to require some above-ground structureson this site ater the construction work has fnished.A ventilation column (approximately 10m highand 1m diameter) would be needed, along with arectangular kiosk (approximately 1.5m high, 1m wideand 3.5m long) housing control equipment.

We would leave the area around these structures ashard-standing to allow or maintenance vehicles andpublic pedestrian access to this area.

Below is an example o how the site could lookater construction has fnished. As part o our publicconsultation, we would like to know your views on thepermanent look and use o the site.
