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.
