Updated: 19:00 02 December 2024

IMPORTANT: We have extended the Boil Water Notice which affects customers living in the following areas: Blaenrhondda, Blaencwm, Tynewydd, Treherbert, Treorchy, Cwm-parc, Ton Pentre, Gelli, parts of Pentre, parts of Tonypandy and parts of Ystrad.

Storm Bert resulted in a significant amount of flooding on site at Tynywaun Water Treatment Works and surface water running from the hill onto the drinking water storage tank and impacting the tank.

Our crews have worked 24/7 to put this right but some of the work to prevent damage from future flooding involves installing waterproof membranes around the storage tank.

A period of dry weather is needed to achieve this successfully and our teams are working around the clock to get it done as quickly as possible.

In the meantime, we are continuing to ask all customers in affected areas boil their water before using it for drinking purposes.

We are delivering bottled water to customers on our Priority Services Register and care homes while also working with key sites such as hospitals.

Water bottle stations have been set up and are open in the following locations:

  • Ynyswen Industrial Estate, Ynyswen Rd, Treorchy, CF42 6ED.
  • Rhondda Sport Centre, Geligaled Park, Tyntyla Rd, CF41 7SY.
  • Co-op, Station Road, Treorchy, CF42 6UA.

We are prioritising vulnerable customers, and are asking people to only take what they need.

What’s Cooking? Welsh Water Hosts Cost-of-Living Event With a Difference


In May we held our first "Cooking On A Budget" Session Cost Of Living Event in Rhyl.

The event was well attended by customers who were able to gather information from the 19 organisations who exhibited, plus Public Health Dietetic Team presented the “Cooking On A Budget” Session.

The aim of the session was to show people how you can make a delicious meal using store cupboard ingredients and to promote how healthy eating also helps with your wellbeing. Tasters of a pre made Bean Chilli, prepared in a slow cooker, was handed out for everyone to sample and each person who attended were also given a bag containing all the ingredients required to make the bean chilli and a recipe book. A big thank you to Morrisons is Rhyl for donating all the food.

We had 2 lucky winners of a slow cooker, they were very pleased and are looking forward to making some nice tasty meals.

S4C came along to film the day as they are doing lots of promotion around cost of living and the benefits to healthy eating.
