A new management approach for the remediation of polluted surface water outfalls to improve river water quality

Abstract

Abstract Comprehensive strategies are required by water companies to effectively manage the remediation of polluted surface water outfalls (PSWOs). This paper describes the approach adopted by Thames Water since 1997. The elimination of diffuse pollution sources by identifying and rectifying domestic and commercial foul to surface water drainage misconnections has resulted in sustainable improvements to the local environment across the Thames region.
