The treated effluent from WADDESDON STW is discharged into local watercourses that ultimately drain into the River Thames catchment. The Thames basin supports diverse aquatic life and is a critical water resource for southeastern England. The plant's secondary treatment helps protect downstream water quality in this ecologically and economically important river system.

WADDESDON STW discharges into tributaries of the River Thames, which flows through London and into the North Sea. The Thames basin is a densely populated and ecologically diverse region, supporting fish populations such as salmon and eels. Secondary treatment reduces organic pollution and nutrient loads, helping to maintain water quality in this sensitive river system.
