Cold Weather – A Message to Our Customers

Updated: 15:00 01 December 2023

We’re experiencing freezing temperatures across many of our communities. This means that there’s a greater risk of water pipes freezing and bursting

We’ll still be working around the clock to keep things flowing smoothly but we also need your help.

We advise all our customers to protect your own water pipes by making sure outdoor taps and pipes are covered and check where your stop tap is just in case you encounter any problems. If you spot any leaks on our network, call us on 0800 052 0130or report online - so that we can get a team out to fix them quickly. 

For hints and tips on how you can prepare your homes for freezing temperatures visit our Winter Ready pages.

Stay safe.

Lead in drinking water


A tighter standard for lead in drinking water came into force in the Water Quality Regulations in December 2013. Lead in water comes from old lead pipes that can be present in properties built before the 1970s.

Over a number of years, Dwr Cymru Welsh Water has invested millions of pounds installing additional treatment (phosphate dosing) at many of our water treatment works to reduce the amount of lead dissolved from lead pipes. We take thousands of water samples every year to test for lead and of these over 99% will achieve the new lead standard.

When we find the level of lead in a water sample is above the regulatory standard we will contact the customer to advise on what to do to reduce their exposure to lead and we will also test neighbouring properties. We will replace any lead pipes that are our responsibility i.e. between the water main and the property boundary. The pipework from the property boundary into the property is the responsibility of the customer.
