Scottish Water has invested £8.7 million in an aerated wetland scheme at Cowdenbeath to improve its combined sewer network.The water company has been working with reed bed specialists ARM Limited and Barhale Construction since September 2013 to design and construct a wetland scheme which will treat the spill flows from two Combined Sewer Overflows (CSOs) for attenuation and treatment before being discharged into the Lochgelly Burn.
Located to the south of Cowdenbeath Golf Course, the £8.7million project involved the construction of two units; the first a flow balancing shaft settlement system for sedimentation of solids and the second a 4,000m2, two metre deep saturated, vertical flow aerated wetland fitted with Forced Bed AerationTM (FBATM).
