HAYFIELD STW - Secondary Wastewater Treatment in High Peak, Derbyshire

HAYFIELD STW is a wastewater treatment plant located in the village of Hayfield, within the High Peak borough of Derbyshire, England. The facility serves a population of around 2,862 residents, providing secondary treatment as part of the region's municipal wastewater infrastructure. The plant is situated in the Sett Valley, near the Peak District National Park, an area known for its natural beauty and ecological sensitivity. The plant operates under the regulatory framework of the UK's Urban Waste Water Treatment Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For a plant serving fewer than 10,000 people, secondary treatment is the standard requirement. The facility has a designed capacity of 3,113 cubic meters per day and currently discharges an average of 637.18 cubic meters per day, indicating ample capacity for future growth. The treated effluent from HAYFIELD STW is discharged into a local watercourse that flows into the River Sett, a tributary of the River Goyt. The Goyt eventually joins the River Mersey, which drains into the Irish Sea via the Mersey Estuary. The plant plays a crucial role in protecting the water quality of these rivers and the downstream estuary, supporting aquatic life and recreational uses.
