Description

Southern Water is advancing two strategic water recycling schemes, Medway and Littlehampton, to deliver up to 33.4 million litres per day of purified recycled water during drought conditions. These schemes will reduce abstraction from sensitive river systems, support environmental destinations, and ensure resilient water supplies for future generations.

The Projects respond to Environment Agency directives to reduce abstraction and to regional forecasts of supply deficits under Water Resource South East (WRSE) and Water Resource Management Plan 2024 (WRMP24) planning scenarios. The schemes are essential to meeting Southern Water's obligations under the Water Industry National Environment Programme (WINEP) and are expected to contribute to achieving environmental destination outcomes in sensitive catchments.
