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.

Customers can access:

Newport Family Event


Welsh Water hosted a free half term family event at The Riverfront Arts Centre in Newport.

Over 30 partner organisations, including Newport City Council, Mind, OVO Energy, Step Change Debt Charity and Tesco, attended to offer information on cost-of-living support, energy saving, mental health and lots more. As well as lots of fun activities for families including face painting, arts and crafts and even plate spinning!

The event had an amazing turn out with over 300 customers in attendance throughout the day.

Jody Perkins, Promotions Advisor, said: “I am thrilled with how yesterday’s event went. The aim was to offer somewhere for families to come together during half term to get information, support and also have lots of fun.

“The turn out was incredible and we were able to offer plenty of advice and support for customers. Early results show we helped over 20 people with debt support on the day, with lots more call backs to do for customers who needed a little more information. We also had lots of customers signing up for water meters, too.

“I’m so proud to have been part of this day and to see all the hard work pay off to make a real difference to the financial wellbeing of our customers.”

Welsh Water stands included members from our Bill and Debt Advice, Vulnerable Customer, Cartref, Employment and Education Teams, who were all able to offer some valuable advice and support with bills, signing up to water meters and improving financial wellbeing. It was a great opportunity to showcase our new first of its kind ‘Cymuned’ support scheme for working families and the cost-of-living support we have on offer.

Feedback from partner organisations has so far been extremely positive, when asked how they’d rate the event.

Ethylle Bering of Pobl Group said: “Excellent, so many families came by and had bags full of things!.... I was also able to give out 200 energy saving lightbulbs so hopefully we have been able to support some families!”
