HURDCOTT STW - Secondary Wastewater Treatment Plant in Winterbourne Earls, Wiltshire

HURDCOTT STW is a wastewater treatment plant located in Winterbourne Earls, Wiltshire, England. It serves a population of 3,326 and operates as part of the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 4,283.00 m³/day and currently discharges 740.48 m³/day of treated effluent. The treated effluent is discharged into a local watercourse that ultimately drains into the River Avon or its tributaries, contributing to the Hampshire Avon catchment. This river system supports diverse aquatic life and flows into the English Channel via Christchurch Harbour.

The plant discharges into a watercourse within the Hampshire Avon catchment, a chalk stream system known for its high ecological value. The Avon flows south through Wiltshire and Hampshire, eventually reaching Christchurch Harbour and the English Channel. The river supports species such as Atlantic salmon and brown trout, and its health depends on maintaining good water quality from upstream treatment plants.
