Welsh Water is encouraging its three million customers to continue 'using water wisely' - even though it may soon start to rain.
It says that after the recent prolonged dry weather, it will be difficult for any rain to penetrate the ground and help restore reservoir levels.
The company is currently safeguarding water supplies following the recent hot and dry weather.
It confirmed that a few of the company's 87 reservoirs are now lower than usual at time of the year, and that this was expected due to the recent weather conditions.
Welsh Water also said that it will take time for the reservoirs to recover to their normal levels, despite the expected rain over the next week.
Welsh Water says that it's teams are out and about working around the clock fixing leaks on the network to make sure as much water as possible is available for customers to use.
Welsh Water are also offering advice on how to save water around the home and garden on their website.
