Liverpool South Woolton STW is a wastewater treatment plant located in the Netherley area of Liverpool, England. It serves a population of around 62,975, making it a medium-sized agglomeration within the United Kingdom's wastewater infrastructure. The plant is situated in the Liverpool City Region, a densely populated urban area with significant industrial and residential wastewater demands. As a UK wastewater facility, Liverpool South Woolton STW operates under the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale (over 10,000 population equivalent), secondary treatment is typically required, with more stringent tertiary treatment if discharging into sensitive areas. The plant's designed capacity is reported as 1.00 (likely in megalitres per day or similar unit), indicating its operational scale. The treated effluent from Liverpool South Woolton STW is discharged into the local water environment, ultimately draining into the River Mersey and then into the Irish Sea. The Mersey Estuary is a vital ecological and economic resource, supporting diverse aquatic life and migratory bird populations. The plant plays a key role in protecting water quality in this important coastal and estuarine ecosystem.

The plant discharges into the River Mersey catchment, which flows into the Mersey Estuary and then the Irish Sea. The estuary is a dynamic environment supporting diverse aquatic life, including fish, invertebrates, and migratory birds. Protecting water quality here is critical for maintaining ecological balance and supporting recreational and commercial activities in the Liverpool Bay area.
