HEATHFIELD HORHAM STW - Wealden, East Sussex Wastewater Treatment Plant

HEATHFIELD HORHAM STW is a wastewater treatment plant located in Horam, near Wealden, East Sussex, England. It serves a population of approximately 14,000 people, classifying it as a medium-sized agglomeration under UK regulations. The plant is situated inland, about 50 km from the coast, and its operations are part of the regional wastewater infrastructure managed by the local water authority. As a UK wastewater treatment facility, HEATHFIELD HORHAM STW operates under the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For a population of this scale, secondary treatment is typically required, with additional nutrient removal if discharging into sensitive areas. The plant's designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating its treatment capability. The treated effluent from HEATHFIELD HORHAM STW is discharged into local rivers and streams that flow towards the English Channel. The receiving water bodies support diverse aquatic life and are important for local ecosystems. The plant plays a key role in protecting water quality in the region, reducing nutrient and pollutant loads before discharge.

The plant discharges into local watercourses within the Cuckmere or Ouse catchment, which ultimately drain into the English Channel. These rivers support diverse aquatic habitats and are used for recreation and agriculture. The downstream environment includes coastal waters that are ecologically sensitive, requiring careful management of nutrient inputs to prevent eutrophication.
