The plant's operation helps protect the water quality of the estuary and downstream marine environment from untreated sewage pollution.

Laceby STW discharges treated effluent into local watercourses that flow into the Humber Estuary, a major tidal estuary on England's east coast. The Humber Estuary supports diverse aquatic life, including fish, invertebrates, and migratory birds. The estuary ultimately drains into the North Sea, a productive marine ecosystem. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this ecologically sensitive coastal environment.
