Ater providers are experiencing supply difficulties due to the warm weather, with some reporting lower pressure levels and others warning of further disruption.
Affinity water said the heat results in lower water pressure in areas such as: London, Essex and Surrey.
The company urged customers to avoid non-essential water consumption and said it forecasts an additional 164 million liters of water will be needed on Monday compared to normal demand.
“Due to the warm weather, many of us use a lot more water,” says the supplier.
“This means you may notice lower pressure or no water when demand is higher in your area.”
Anglian Water, which operates in the east of Englandsaid sudden high demand due to “extremely warm weather” is likely a contributing factor to causing water supply cuts in King’s Lynn over the weekend.
A spokesman said his teams are working to restore water supplies “as soon as possible” in some areas of King’s Lynn following a burst water main.
Similar weather-related delivery issues are occurring in Bristolwith the Bristol Water Foundation warning that this week’s heat wave could affect water pressure and taste.
“As the weather gets warmer, you may experience a drop in water pressure, especially during peak times,” it told customers.
“As the temperature rises, water consumption increases as we all try to cool off with showers, hoses and paddling pools, increasing demand on our network.”
It said the water supply could be temporarily diverted so that customers’ water comes from treatment plants or reservoirs other than normal.
“This may mean that you notice that your water tastes a little different than usual. But don’t worry, this will return to normal when temperatures start to cool down again,” the report said.
Meanwhile, South East Water reported supply problems in the Challock and Molash area of Kent on Sunday, caused by an unprecedented amount of water consumption.
The company has set up a bottled water station, telling customers that the ongoing warm weather and increased demand for water have “put a significant strain on our network.”
South East Water told PA news agency: “Despite seeing record demand for water, we are currently seeing minimal customer deliveries interrupted by the warm weather in our water supply area in parts of Kent, Sussex, Surrey, Hampshire and Berkshire.
“We would like to thank our customers who have listened to our reports on water efficiency and ask them to step up their efforts to reduce their water consumption as we enter the hottest period yet.
“In the villages of Challock and Molash we have repurposed our water network so some customers still have a supply of water but there may be a few without so we have set up a bottled water station in Challock village hall which will be open until 9pm hour.”
