The Counters Creek Sewer Flooding Alleviation Scheme aims to reduce the risk of flooding to over 1,700 basement properties within the Counters Creek catchment.
Heavy rainfall in July 2007 caused widespread basement sewer flooding in the London Borough of Hammersmith and Fulham and the Royal Borough of Kensington and Chelsea. A number of properties also flooded during storms in 2004 and 2005, with some residents reporting sewer flooding up to six times in recent years.
Why does basement flooding occur?
When sewers become overwhelmed by storm water runoff, the local sewer water levels rise and back up the sewerage network into basement properties.
What are we doing?
We have identified the cause of flooding in the area and established the best solution to reduce the problem. The scheme is composed of the following main elements:
- A new storm relief sewer
- Sustainable drainage systems (SuDS)
- Anti-flooding devices (FLIPs)
- Local sewer improvements
