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:

June 2022


In North Wales our focus throughout June was in Flintshire. Most of the events were in the community exhibition van for our “Cost Of Living Roadshow” in places such as Flint Retail Park, ASDA Queensferry, Broughton Retail Park and Aldi in Buckley.

The weather was glorious with plenty of nice warm sunshine, which called for one or two ice creams to cool us down!

We had the opportunity to speak to lots of people who were seeking advice on their water and energy bills. Thank you to Warm Wales, Nest, Groundworks North Wales, DWP Welfare Team, Citizen Advice and Woodys Lodge who all supported Tracey Jones on the van.

If you are interested in coming along to any of the roadshows or would like us to bring the van to one of your events, please get in touch. We also attended events at Soughton Hall, organised by Newcis and Mostyn Village Hall as part of the Cost Of Living Road Shows.

It has been a busy month across June for the South Vulnerable Customer Community Team.

We have taken ourselves deep into our communities to reach those who cannot reach us. There has been supermarkets, baby showers, schools, libraries food pantries, community centres, hospitals and more!

There's nowhere we won't go to reach our most vulnerable of customers!
