It is subject to regulation by the Environment Agency. The treated effluent from Bowden STW ultimately discharges into local watercourses that drain into the River Mersey catchment, which flows into the Irish Sea. The plant plays a role in protecting the water quality of the Mersey Basin, supporting aquatic ecosystems and downstream water uses.

Bowden STW discharges into the River Mersey catchment, which drains into the Irish Sea via the Mersey Estuary. The Mersey Basin is an ecologically important area supporting diverse aquatic life, including migratory fish species. The plant's treatment helps reduce nutrient and pollutant loads, contributing to the health of the estuary and coastal waters.
