DUNHOLME STW Wastewater Treatment Plant, West Lindsey, England

DUNHOLME STW is a wastewater treatment plant located in West Lindsey, Lincolnshire, England, serving a population of about 5,961. The facility is situated on Mickleholme Road in the Dunholme civil parish and is part of the region's municipal wastewater infrastructure. As a plant serving a small agglomeration, DUNHOLME STW is subject to the UK's implementation of the EU Urban Waste Water Treatment Directive, which requires appropriate treatment based on the size of the population and the sensitivity of the receiving environment. The plant's designed capacity is 1.00, indicating its scale relative to the population served. The treated effluent from DUNHOLME STW is discharged into local watercourses that ultimately drain into the North Sea via the River Witham or nearby tributaries. The surrounding area includes agricultural land and rural settlements, and the plant plays a key role in protecting local water quality and downstream ecosystems.

DUNHOLME STW discharges into the River Witham catchment, which flows through Lincolnshire and into The Wash, an estuary of the North Sea. The Wash supports diverse aquatic life, including important bird populations and fish species. The plant's treatment helps maintain water quality in this ecologically sensitive area, reducing nutrient loads that could contribute to eutrophication in the estuary.
