Ferndown, Verwood, West Moors, and St Ives STW - Hurn, England Wastewater Treatment Plant

Ferndown, Verwood, West Moors, and St Ives Sewage Treatment Works (STW) is a municipal wastewater facility located near Hurn, in the Bournemouth, Christchurch and Poole area of Dorset, England. The plant serves a combined population of around 40,798 people from the surrounding communities, making it a medium-sized agglomeration under UK classifications. As a UK wastewater treatment plant, it 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 equivalent of this scale, the regulations require secondary treatment as a minimum, with more stringent treatment if the discharge is to a sensitive area. The plant's designed capacity is reported as 1.00 (likely in megalitres per day or similar units), indicating its operational scale. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the English Channel via the Stour or Avon river systems. The receiving waters support diverse aquatic life and are important for regional biodiversity. The plant plays a key role in protecting the water quality of these rivers and the downstream coastal environment, which includes ecologically sensitive habitats such as estuaries and heathlands.

The plant discharges into the River Stour or River Avon catchment, which flows into Christchurch Harbour and then the English Channel. This coastal and estuarine environment supports diverse aquatic life, including salmonids and migratory birds. The area is ecologically sensitive due to its heathland and wetland habitats, which depend on good water quality.
