Can Desalination Solve the UK’s Drought Crisis?
For an island nation famous for grey skies and drizzle, the concept of a water shortage feels counterintuitive. Yet, as consecutive heatwaves and prolonged dry spells push reservoir levels down and trigger hosepipe bans and abstraction restrictions across multiple regions, water security has moved firmly to the top of the national agenda. With chalk streams under pressure and river levels dropping, the question inevitably resurfaces: why aren't we turning the sea around us into drinking water? Can we use water from the sea to avoid drought restrictions in the UK? The UK’s Desalination Landscape Desalination remains remarkably rare in the UK. The country’s sole large-scale mainland plant is the Thames Gateway Water Treatment Works in Beckton, East London. Commissioned in 2010 to provide up to 150 million litres of water a day during extreme dry periods, the plant treats brackish water from the tidal Thames using reverse osmosis. Beyond Beckton, desalination is limited to nich...
