Battersea Power Station Decomissioning

Client:Skanska, Carillion & Blu-3
Discharge Point:Foul Sewer
Flow Rate:50m³/hr

Background

Battersea Power Station A was built in the 1930s, with Battersea B Power Station to the east in the 1950s. The two stations were built to a nearly identical design, providing the long-recognized four-chimney layout. The station ceased generating electricity in 1983, but over the past 50 years it has become one of the best known landmarks in London.

During decommissioning a large area of hard standing was being used as a holding area for stockpiles of potentially contaminated soil, excavated from the Battersea Power Station site. During periods of heavy rain, large volumes of water runoff from he stockpiles caused local flooding of site roads and potentially silting up surface and foul drainage.

The Overall Objective

The resulting water runoff due to the heavy rain led to the requirement of a treatment system capable of dealing with up to 50m³/hr of water.

Solution

Siltbuster provided a HB50 settlement unit to help treat the water and prevent the site from flooding, whilst discharging only treated water to foul sewer under Consent to Discharge regulated by Thames Water.
