RIPON STW - Wastewater Treatment Plant in Ripon, North Yorkshire, England

RIPON STW is a municipal wastewater treatment plant located on Fisher Green Lane in Ripon, North Yorkshire, England. It serves an estimated population of 18,661, placing it in the medium agglomeration category under UK and EU regulatory frameworks. As a plant of this scale in England, RIPON STW operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges from agglomerations above 2,000 population equivalent. The plant's treatment process ensures compliance with standards for biochemical oxygen demand and suspended solids. The treated effluent from RIPON STW is discharged into a local watercourse that feeds into the River Ure, a major tributary of the River Ouse in Yorkshire. The River Ure flows through the Yorkshire Dales and ultimately drains into the Humber Estuary, supporting diverse aquatic life and providing water for agriculture and recreation.

The plant's discharge enters a tributary of the River Ure, which flows through the Nidderdale Area of Outstanding Natural Beauty and the Vale of York before joining the River Ouse. The Ouse then drains into the Humber Estuary, a large tidal estuary that supports important bird populations and fish species. The catchment is ecologically sensitive, with habitats for salmon, trout, and otter populations.
