Basingstoke Wildmoor Basingst STW - Wastewater Treatment Plant in Hampshire, UK

Basingstoke Wildmoor Basingst STW is a wastewater treatment plant serving the Basingstoke and Deane area in Hampshire, England. It treats wastewater from a population of around 117,000, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is located near the village of Wildmoor, with its address on Whitemarsh Lane. As a large agglomeration, the plant is expected to provide secondary treatment as a minimum under the UWWTD, with tertiary treatment required if discharging into a sensitive area. The River Loddon and its tributaries are designated as sensitive areas under the directive, which may necessitate advanced treatment to reduce nutrients and protect water quality. The treated effluent from the plant discharges into the River Loddon, a tributary of the River Thames. The Thames flows through London and into the North Sea. The plant plays a crucial role in protecting the River Loddon and downstream ecosystems from pollution, supporting aquatic life and recreational use of the river.

The plant discharges into the River Loddon, which flows into the River Thames and eventually the North Sea. The River Loddon is a chalk stream, a rare and ecologically sensitive habitat that supports diverse aquatic life including brown trout, grayling, and water voles. The catchment is also important for groundwater recharge and biodiversity, with several Sites of Special Scientific Interest (SSSIs) along its course.
