As Wales enjoys the warm climate, people are urged to “be careful” with their use of water.

Wales saw the hottest beginning of May registered on Thursday, with temperatures that date back to 27.6c (80f) in Cardiff.

Welsh Water said his resources were in a “good position”, but that the deposits were “just below what is expected at this time of the year,” he added that they were disaster efforts to move the water where the demand was higher.

The director of Water Services, Marc Davies, said: “Use the water you need but it does not waste it. It is things like when you brush your teeth, to turn the decrease.”

Davies said he was asking everyone to work together after seeing the fourth more seca registered.

He added: “If people use their rowing pools during the weekend in this good weather, making sure to keep that water and use it for the garden.”

The Welsh Water supply originates largely in reservoirs and rivers, which can make it vulnerable to the driest climate periods.

Davies said the company was also establishing measures to address the effect of warm climate, including the adjustment of water levels supplied from some deposits.

The CRAI reservoir levels in Powys have fallen, so the company is now drinking more water from its Felindre deposits in the Swansea valleys.

Welsh Water said he was also working to reduce the amount of water that is lost from his systems through leaks.

The Chief of Water Engineering, Chris Rees, said that more than 15,000 smart sensors had been installed in the 18,641 miles (30,000 km) network to help detect leaks.

These sensors are “listening to leaks at all times,” he said, and they give the company an immediate notification of a filtration that occurs in the network that can be followed by an inspector.

People can also inform a leak if they believe they have one.

Chris Rees says that leak detection is important throughout the year to safeguard water supplies

The company said it had £ 400 million planned investment for the replacement of pipes and leak repairs in the next five years.

“Reducing the leak really helps us with our position of water resources as the weather dries and we get less rain and storage in our system,” Rees said.

“While the escape is very important for us when it is dry, we address leaks throughout the year. It is a very important part of our resilience for water resources in the future.”

How can you save water?

Do not leave the tap running while the hands are washed or brush your teeth
Take a shower or bath
Wait until the washing machine and dishwasher are full before putting them
Do not fill the rowing pool to the top and when it is over, use the water in the plants in the garden
Do not use a spray on the grass to keep it green: the color will soon return once it rains

Welsh Water said his Get Water Fit calculator also provides additional tips to save in water and water invoices.
