ELDMIRE STW - Secondary Wastewater Treatment Plant in Topcliffe, England

ELDMIRE STW is a wastewater treatment plant located in Topcliffe, North Yorkshire, England. It serves a population of 2,692 and operates under secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local watercourses. The plant has a designed capacity of 2,847 m³/day and currently treats an average daily flow of 599.33 m³/day, indicating it operates well below its maximum capacity. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids, meeting the regulatory standards set by the UK Environment Agency under the Water Resources Act 1991. The treated wastewater from ELDMIRE STW ultimately drains into the River Ure catchment, which flows into the Humber Estuary and then the North Sea. This river system supports diverse aquatic life and is important for local biodiversity. The plant's operation helps protect the water quality of the River Ure and its downstream environments.

ELDMIRE STW discharges into the River Ure catchment, which flows through North Yorkshire and joins the River Ouse, eventually reaching the Humber Estuary and the North Sea. The River Ure supports a variety of fish species, including salmon and trout, and its riparian habitats are ecologically sensitive. The plant's secondary treatment helps reduce nutrient and pollutant loads, safeguarding the river's health and the downstream estuarine ecosystem.
