KINGSLEY STW - Secondary Wastewater Treatment Plant in Crowton, England

KINGSLEY STW is a wastewater treatment plant located on Kingsley Road in Crowton, Cheshire West and Chester, England. The facility serves a population of approximately 3,287 and operates as part of the United Kingdom's wastewater infrastructure under the regulatory framework of the Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, which is the standard required by the UWWTD for inland and coastal discharges from agglomerations of this size. The designed capacity of the plant is 3,770 m³/day, and the current discharge volume is 731.80 m³/day, indicating operational capacity well within design limits. The treated effluent is discharged into the local water environment, ultimately reaching the River Weaver and then the River Mersey estuary, which flows into the Irish Sea. The plant's proximity to the coast (within 10 km) means its discharge is subject to stringent environmental standards to protect coastal and marine ecosystems.

The plant discharges into the River Weaver catchment, which drains into the River Mersey estuary and then the Irish Sea. This coastal zone supports diverse aquatic life and is an important area for migratory birds and fish species. The secondary treatment provided helps reduce organic pollutants and protect the downstream estuarine and marine environment from nutrient enrichment and oxygen depletion.
