The Thames Gateway Water Treatment Works or Beckton Desalination Plant is a desalination plant in Beckton, London, adjacent to Beckton Sewage Treatment Works. The plant takes brackish water from the River Thames and converts it into drinkable water through a reverse osmosis process. The first of its kind in the UK, it was built for Thames Water by a consortium of Interserve, Atkins Water and Acciona Agua. It was opened by Prince Philip, Duke of Edinburgh, on 2 June 2010. It was planned to provide up to 150 million litres of drinking water each day enough for 900,000 Londoners. but by 2023 had only operated on three occasions, and at two-thirds of its planned capacity.
