South West Water has come under sharp criticism after advising Britons, especially parents, to limit water use during a record-breaking heatwave—even though reservoirs are currently about 90% full.
Serving Dorset, Somerset, Devon, and Cornwall, the company reminded the public to be cautious when filling children’s paddling pools as temperatures soar this summer. This advice has frustrated many residents, given the recent history of heavy rainfall in these regions. Cornwall recorded its wettest winter since 1836, and Somerset faced such severe flooding that a major incident was declared.
As Britain bakes under soaring temperatures that have reached a staggering 35°C in May, some residents see little reason to save water. Cornwall resident Liz Northcott, 74, told The Sun, “My great-grandchildren are in the paddling pool, and there will be no half measures. They don’t have a shortage, so why tell us to use less water?”

Adding fuel to the controversy, South West Water was fined £24 million in March after a series of serious sewage spills. Critics have questioned why the company is urging cutbacks during a historic heatwave when issues like leaking pipes and water contamination remain unresolved.
South West Water insists that its call for wise water use is consistent year-round, regardless of weather conditions. Industry experts warn that sudden spikes in demand during heatwaves place significant strain on water infrastructure, even if reservoir levels appear sufficient.
Elsewhere in the UK, water systems already show signs of stress. In the south-east, including Kent and Sussex, rising consumption has led to reduced water pressure and supply interruptions. South East Water reported that on May 25th, 670 million litres of drinking water were used—nearly 100 million litres above the average for this time of year. This surge has depleted reservoir levels in parts of Kent, and tanker fleets are working around the clock to meet demand.
Customers on higher ground or at the network’s edges may experience low water pressure or supply disruptions, especially during peak times. These intermittent outages are expected to persist until cooler temperatures reduce demand.
Meanwhile, families are flocking to Britain’s beaches and parks to cool off during the half-term holiday. Sales of fans, ice, and sunscreen have skyrocketed as households seek relief and protection from the intense sun.
