This Coal Authority treatment scheme is part of a strategy to prevent uncontrolled discharges to surface watercourses and also protect the aquifer in the area, which is one of the most important sources of drinking water in the Midlands.
Based in a strategic location, the scheme protects the aquifer due to its underground connections between the abandoned coal mines.
Improving water treatment
We constructed larger lagoons and a reed bed on land previously used by the mining operator to treat water as part of their surface mining project. The redesigned scheme improved the treatment of the water. We also refurbished the pump station and installed a transfer pipe.
Water is pumped from the shaft at the pump station, across a brook and to the treatment cascade which aerates the water. It then flows into the two lagoons and a wetland. Naturally occurring processes then treat the water, without the need to add any chemicals.
