UK’s biggest sustainable urban drainage system proposed for capital location

The biggest sustainable urban drainage system (SuDS) in the UK, an ambitious new project designed to dramatically cut the amount of clean rain water mixing with sewage, is set to be launched this summer across the Nine Elms South Bank regeneration area.

Rainwater landing on an area the size of 20 football pitches will be channelled back into the Thames to stop it entering the capital’s overstretched sewers where it would mix with raw sewage.

This will reduce flood risks and save the huge amount of energy and cost involved in treating rainwater after it combines with waste from sinks, toilets and washing machines.

The £17m scheme has been developed through an innovative partnership between Thames Water and the Nine Elms Vauxhall Partnership, which includes Wandsworth Council, Lambeth Council, the GLA and local developers including Ballymore.

New developments in Nine Elms have pioneered design features in new buildings and landscaping that capture rainwater, and increase evaporation before directing flows to a surface water network.

The rainwater will then drain into large underground pipes buried beneath the new Nine Elms Park which will be a new green channel through the area from Vauxhall to Battersea Power Station.

After heavy rainfall the water will be gradually pumped from this underground reservoir into the Thames via an upgraded pumping station in Ponton Road.
