Britain is facing growing concerns over its water supply amid the worst drought in 31 years, with critics pointing to the role of water companies and the adequacy of current infrastructure plans. Recent drought conditions have drawn attention to longstanding issues such as significant water loss, regional shortages, and the need for improved national water management strategies.
Environment Minister Emma Hardy, addressing Parliament last week, emphasized the importance of conserving water during the ongoing drought. However, some lawmakers and members of the public have responded with criticism, highlighting the financial practices of water companies. Edward Morello, a Member of Parliament, cited data showing that South West Water lost 107 million litres of water daily last year, an amount exceeding 100 litres per customer per day. He also noted that since 2013, the company has received £40 million annually from central government while distributing over £1.5 billion to shareholders. Such figures have raised questions about water companies’ incentives to reduce wastage.
Calls have grown for more immediate investment in water infrastructure, with Labour pledging the construction of nine new reservoirs. Critics argue, however, that the planned reservoirs are too few and too far in the future, with some projects not expected for 25 years. Jane Knott of Blandford Forum in Dorset stressed the urgency for new reservoirs to address the drought and ensure long-term supply security.
Additional voices have advocated for a national approach to water management, citing the inefficiency of regional frameworks in coping with climate change-induced shortages. John Palmer from Liphook, Hampshire, urged the government to direct water companies to collaborate and develop a national water grid. Palmer also highlighted the loss of millions of gallons of rainwater being discharged into the sea or polluted rivers instead of being stored for future use.
The proposed White Horse Reservoir in Oxfordshire—estimated to cost nearly £6 billion and with a capacity of approximately 150 billion litres—has drawn skepticism. Thames Water plans to fill it over two years from the River Thames, but concerns remain about the river’s flow and water quality amid drought and pollution. Marion Mantle of East Hanney questioned whether the reservoir risked becoming an ineffective investment, likening it to other costly infrastructure projects with uncertain returns.
Some experts and commentators suggest that desalination could offer a more reliable and scalable solution. Currently, the UK has only one mainland desalination plant at the Thames Gateway in East London, which is under repair, along with two smaller plants in Jersey and the Scilly Isles. In contrast, countries in southern Europe have developed numerous desalination facilities—Spain has 700, Greece six, Cyprus and Gibraltar five each, and Malta four. Sandy Pratt of Storrington, West Sussex, questioned the lack of political will to expand desalination as part of a national water strategy.
With climate projections indicating more frequent and intense droughts, the debate over how best to secure the UK’s water future is likely to intensify, focusing on balancing infrastructure investment, corporate accountability, and innovative solutions.
