OLD LEAKE SKIPMARSH LANE STW - Boston, England Wastewater Treatment Plant

OLD LEAKE SKIPMARSH LANE STW is a wastewater treatment plant located in Old Leake, near Boston in Lincolnshire, England. The facility serves a population of approximately 2,597 and operates under the regulatory framework of the United Kingdom, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. The plant provides secondary treatment, which is the standard required for inland freshwater discharges under the directive. The designed capacity of 2,597 population equivalent aligns with the population served, indicating the plant is appropriately sized. The daily discharge volume of 578.18 cubic meters reflects the scale of the community it serves. The treated effluent is discharged into local watercourses that drain into the North Sea via the Wash, an ecologically important estuary. The plant plays a key role in protecting the water quality of the surrounding fenland drainage system and the downstream marine environment.

The plant discharges into the drainage network of the Lincolnshire Fens, which ultimately flows into the Wash, a large estuary on the North Sea coast. The Wash supports diverse bird populations and is a vital habitat for migratory waterfowl. The secondary treatment provided helps reduce nutrient and organic loads, protecting the sensitive downstream ecosystem from eutrophication.
