KILSBY STW - Secondary Wastewater Treatment Plant in Kilsby, England

KILSBY STW is a municipal wastewater treatment plant located in Kilsby, West Northamptonshire, England. The facility serves a population of approximately 2,286 people and operates with a designed capacity of 2,750 m³/day, with an average daily discharge of 508.94 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland agglomerations of this size. As a small agglomeration (under 10,000 population equivalent), secondary treatment is appropriate for protecting receiving water quality. The treated effluent is discharged into local watercourses that ultimately drain into the River Avon or River Nene catchment, both of which flow into The Wash, a large estuary and ecologically important area on the east coast of England. The plant plays a key role in maintaining water quality in the region's freshwater ecosystems.

The plant discharges into local streams that are part of the River Avon or River Nene basin, both of which drain into The Wash, a major estuary on England's east coast. The Wash supports diverse aquatic life, including migratory fish and bird populations, and is an important area for conservation. The secondary treatment provided by KILSBY STW helps reduce nutrient and organic loads, protecting downstream water quality in this sensitive coastal environment.
