Welsh Water has issued a warning as a prolonged heatwave drives a major increase in water demand, bringing the system closer to the point where supplying water quickly enough becomes increasingly challenging. The company reported that water use is 17% higher than usual, with demand remaining elevated for much longer each day and into the night.
Record Demand Levels
Since June 21, demand has hit 900 megalitres per day, rising to more than 950 megalitres per day from Monday, July 6, and exceeding 1,000 megalitres per day from Thursday, July 9. Normal demand for Welsh Water is around 850 megalitres per day, meaning the company is managing an increase of 150-200 megalitres daily—equivalent to 264-352 million pints of water.
Welsh Water said hundreds of staff are working around the clock to increase water production, move water across the network, and fix leaks as quickly as possible. Despite these efforts, the company warned it is getting closer to the point where supplying water quickly enough to meet demand becomes increasingly challenging.
Appeal for Customer Help
Kit Wilson, Welsh Water's Chief Customer Officer, said: "The extreme heat and prolonged dry weather in this third heatwave of the year means people are using much more water and for much longer throughout the day. Our teams are working around the clock, treating more water, moving supplies with tankers and fixing leaks. But we need customers' help too."
Wilson added: "Small changes made by lots of people would make a big difference. By using water wisely, customers can help us keep water flowing and avoid the need for further measures if the hot weather continues."
Simple Water-Saving Tips
Welsh Water is encouraging customers to make simple changes, such as using a watering can instead of a sprinkler, letting lawns recover naturally, reusing water from paddling pools on gardens, chilling water in a jug in the fridge instead of running the tap until cool, and running washing machines and dishwashers with full loads.
"These small actions can save millions of litres of water and help protect supplies for communities and the environment," Welsh Water said.
