ECCLESHALL STW Wastewater Treatment Plant, Eccleshall, Staffordshire, England

ECCLESHALL STW is a wastewater treatment plant located in Eccleshall, Staffordshire, England. The facility serves a population of approximately 5,232 people, classifying it as a small agglomeration under UK wastewater regulations. The plant is situated inland, away from coastal areas, and discharges into local watercourses within the River Trent basin. As a small agglomeration in the United Kingdom, ECCLESHALL STW is subject to the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive. These regulations require secondary treatment for discharges to freshwater and estuaries, with more stringent tertiary treatment if the receiving water is designated as sensitive. Typical UK plants of this scale employ secondary biological treatment. The treated effluent from ECCLESHALL STW ultimately drains into the River Sow, a tributary of the River Trent, which flows into the Humber Estuary and the North Sea. The River Trent supports diverse aquatic life and is an important ecological corridor. The plant's operations help protect water quality in this catchment, reducing nutrient and pollutant loads that could otherwise impact downstream habitats.

ECCLESHALL STW discharges into the River Sow, a tributary of the River Trent. The Trent flows through the Midlands into the Humber Estuary, a major ecological area supporting migratory fish and bird populations. The plant's location in a rural catchment means its effluent can affect local stream ecology, particularly during low-flow conditions. Protecting water quality here is important for maintaining the health of the broader Trent basin.
