A SPEL ESR Bypass 215C1/ESR was installed to treat the surface water run-off from the Lifestyle Centre car park before the stormwater was attenuated and slowly released by a flow control chamber.
This site was discharging to a chalk aquifer and therefore the Environment Agency asked the contractor to install a SPELFilter system. The SPELFilter Cartridges (factory fitted within a SPELFilter Chamber) were installed down stream of the attenuation tank to remove the dissolved pollutants that the EA would not allow to be released into the chalk aquifer, which is a drinking water source. The SPELFilter removes both very fine sediment and also dissolved pollutants such as nitrogen, phosphorus and dissolved metals. 2no. SPELFilter Chambers, each with 6 SPELFilter cartridges factory fitted inside to treat 18 l/s each on two separate discharges from the site.
