Notice of sewer protection works in Blenheim Crescent

What we are doing

What we are doing
Ahead of tunnelling later this year, we will be carrying out sewer protection works on Blenheim Crescent from 13 June to 16 July 2022. On two occasions we will be working between the hours of 7am and 10pm on Saturday 2 and 16 July 2022. We will be working on a sewer under the Chiltern mainline and Central Line of the London Underground.

The main sewer protection works consist of relining the foul and surface sewer network in Blenheim Crescent and replacing and reinstating maintenance covers. We will be using water tankers during the works, should we need to flush the sewer system.

Some vegetation will be cleared to allow for clear access to our working areas.

You may hear additional noise during these works. We will use noise reducing barriers as well as other methods to assist with mitigation. We will set up a site compound at the end of the garages behind Blenheim Crescent. We will install fencing to segregate our work area. See map overleaf the location of our works and welfare unit.

Your water supply will not be affected.

How these works might affect you
During the first phase of works there will be temporary traffic management in place. There will be lane closures with a three-way traffic light and there will be footpath closures on Blenheim Crescent for one week. There will be some small footpath diversions in place, which will be clearly signposted.

We would like to apologise in advance for any disruption or inconvenience this may cause. Every effort is being taken to ensure that these works are carried out in the least impactful way. We will ensure that disruption is kept to a minimum.
