Brent mains replacement

We’re making significant investment to replace our mains pipes in Brent. The pipes will be more durable, which will reduce the risk of leaks, bursts, and flooding. This will provide a more reliable service for the growing population over the next 100 years.

When and where we'll be working

We're currently working on the following roads:

  • Balnacraig Avenue
  • Birse Cresecent
  • Chatsworth Road
  • Denzil Road
  • High Road
  • St Pauls Avenue

Letters will be sent to residents prior to our work commencing on your road. We will update this information as the project progresses.

Our standard working hours will be Monday to Friday 8am to 6pm and Saturday 8am to 1pm.

How this may affect you

We’ll do everything we can to minimise any disruption to you while we repair the main. However, you may be affected by the work in the following ways:

  • Traffic disruptions - we'll use road closures in 100m to 150m sections. This could cause traffic disruptions. Diversion routes will be signposted. We'll contact residents by letter if we're due to start work on your road
  • Parking - we'll be implementing parking bay suspensions. Please look out for our on-street and path signage
  • Water supply - we may need to turn off your water supply for a short time. If so, we’ll send you a letter with more details at the time
  • Closed road lanes and footpaths - this will be around the areas where we're working
  • Noise at the site - this is likely during working hours. We're sorry for any inconvenience and will try to keep disruptions to a minimum

Access will be maintained for residents, businesses and emergency vehicles. Driveways will remain open as much as possible.

Techniques we'll use

We'll use different methods to complete the project, such as:

Sliplining

We'll insert new pipeline through the existing Victoria Main to reduce disruption.

CCTV survey

Post installation surveys to confirm alignment with specifications.

Open-cut method

Only where necessary, we'll excavate ground to install new pipework.
