We are proposing to use the foreshore of the River Thames, opposite the Bull Ring Gates of the Royal Hospital Chelsea, a section of Chelsea Embankment (A3212) and part of the grounds of the Royal Hospital Chelsea for construction work. We also need to accommodate permanent structures required to operate the main tunnel.
The sites would be used to intercept the existing local CSO, known as the Ranelagh CSO and to construct a connection to the northern Low Level Sewer No.1 to divert flows to the main tunnel.
These works, along with our works at Blackfriars Bridge Foreshore and Victoria Embankment Foreshore mean that we do not need additional sites to intercept the following CSOs along the northern embankment: Smith Street, Queen Street, Church Street, Grosvenor Ditch, Kings Scholars Pond, Western Pumping Station, Northumberland Street, Savoy Street, Norfolk Street and Essex Street.
The two construction sites required for the works at Chelsea Embankment Foreshore are shown below. The main site is located in the foreshore of the River Thames, with part of the site extending north onto the Chelsea Embankment (A3212), along which the Thames Path is located and the south eastern part of the grounds of the Royal Hospital Chelsea. The site is also within the Thames Conservation Area. To the east of the main site is Chelsea Bridge. Ranelagh Gardens and the Royal Hospital Chelsea, (together a Grade II registered park and garden), lie to the north of the main site, separated from it by Chelsea Embankment (A3212).
The smaller site, which is required to connect the northern Low Level Sewer No.1 to the main tunnel, is located within the eastbound carriageway and footpath of the Chelsea Embankment (A3212) and the southern part of Ranelagh Gardens.
Chelsea Embankment Foreshore (opposite to Bull Ring Gate) is our preferred site to intercept the Ranelagh CSO. The site would have less effect on the foreshore of the River Thames because it is only necessary to build one structure. There is also likely to be less effect on local residential areas. The location of the site also offers the opportunity to create a new area of public space that complements the setting of the historic environment and views along the River Thames. The northern Low Level Sewer No.1 connection would be constructed within the existing eastbound carriageway of Chelsea Embankment (A3212). These works would be in the same location for each of the shortlisted sites.
