NEWICK STW: Secondary Wastewater Treatment Plant in Newick, Lewes, East Sussex

NEWICK STW is a wastewater treatment plant located near Newick, a village in the Lewes district of East Sussex, England. The plant serves a population of around 3,100 and operates under the regulatory framework of the UK Environment Agency, which enforces standards aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's designed capacity is 3,109 population equivalent, and it treats an average daily flow of approximately 692 cubic meters. Under the UK's implementation of the UWWTD, agglomerations of this size (2,000-10,000 PE) are required to have secondary treatment, which NEWICK STW provides. The plant is operated as part of Southern Water's network, though specific operator details are not disclosed here. The treated effluent is discharged into a local watercourse that eventually drains into the River Ouse, which flows through the Sussex countryside before reaching the English Channel at Newhaven. This water body supports diverse aquatic life and is used for recreational activities. The plant's operation helps protect the river's water quality and the downstream coastal environment.

The treated effluent from NEWICK STW enters a local stream that feeds into the River Ouse, a chalk stream that flows through the South Downs National Park. The River Ouse is ecologically sensitive, supporting species such as brown trout and Atlantic salmon. It ultimately discharges into the English Channel at Newhaven, a coastal area important for marine biodiversity. The plant's secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in the downstream estuary and coastal waters.
