Package wastewater treatment plant in Scotland

ABVEast (AMEC and Black and Veatch) has supplied a new 250 PE package wastewater treatment plant, designed and built at Stenton WWTW in East Lothian for Scottish Water Solutions.
As part of the works undertaken by ABVEast (a joint venture of AMEC Capital Projects with Black and Veatch), a new 250 PE package wastewater treatment plant has been designed and built at Stenton WWTW in East Lothian as part of a multi-million design and build framework within Scottish Water Solutions. The new works, which has to meet the Urban Wastewater Regulations (Scotland), sees the replacement of two former septic tanks and provides a final effluent quality of 20 mg/l BOD, 30 mg/l suspended solids. Design, environmental reporting and landscape design was carried out by Black and Veatch, including a significant amount of work carried out in the siting of the works.
Lengthy consultation was required with the local community to provide a design that blended into the existing environment of the conservation village.
Construction of the works by ABVEast saw new interceptor sewers to divert flows to the new works and the new package plant comprising inlet screens, flume, combined primary settlement tank and rotating biological contactor (RBC), final settlement tank and control building.
