The solution designed and constructed by DPW was chosen based on its capability, flexibility and reliability to serve the future catchment needs over a 25-year projection horizon ensuring that NI Water and SWELL targets were met.  The new works was successfully tested, commissioned and handed over to NI Water in February 2021 and is comfortably meeting the NIEA final effluent quality standard of 40 mg/l BOD, 60 mg/l suspended solids and 20 mg/L ammonia.  This hi-tech wastewater treatment solution will accommodate development in the Donemana area and offer increased environmental protection for the adjacent Burn Dennet River and thus the Foyle Estuary for many years to come.
