Boil Water Notice!

exclamation icon

Updated: 11:00 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 so our efforts have been hampered by further wet weather this week and there is more rain forecast for the weekend.

Our teams will continue to work 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.

We are sorry for the inconvenience this incident has caused.

Boil Water Notice extension - Open letter to customers from our Chief Executive Peter Perry.
