Boil Water Notice!

exclamation icon

Updated: 10:00 27 November 2024

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

Due to Storm Bert, extensive flooding has impacted Tynywaun Water Treatment Works in Treherbert.

This means that we have now issued a precautionary ‘boil water’ notice to households in Blaenrhondda, Blaencwm, Tynewydd, Treherbert, Treorchy, Cwm-parc, Pentre, Ton Pentre, Gelli and Tonypandy areas.

We ask that all customers boil their water with immediate effect before using it for drinking purposes. We are sorry for the inconvenience this will cause but we are working to restore supplies back to normal as soon as possible.

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

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

Support with bills


If you're having trouble affording to pay your bill, please don't ignore it. We have a number of ways we may be able to help you and make your bills more affordable.

Advice if you are struggling to pay your bill, or think you may struggle in future, but aren't in debt...

If you are in debt on your account, more advice is available further down this page.

Spread the cost of your bill

You can pay by instalments weekly, monthly, or 6 monthly, rather than paying in full when you receive your bill. Most of our customers prefer to pay by Direct Debit as it spreads the cost without charge, the payments are taken automatically, and it's covered by our Direct Debit guarantee. Alternatively you can set up a payment card if a direct debit isn't for you.

Save money with a water meter

If you live alone, don't use much water, or are just looking to reduce your bill then you might save money by having a water meter installed, that way you'll only pay for the water you use. If you already have a water meter then you can save money by saving water, more information on how to be efficient with water is available here.

Request a short term payment break

If your problem is just a short term one, and you need a little help, we can temporarily reduce or postpose payments. You can apply for short term help online and we will review your circumstances and call you back with options which are suitable for you. You can do this using our online form.

If you receive benefits or have a low income

If you are already paying by instalments and you're still struggling, please don't ignore any problems. Take a look at our other schemes which might be able to help if you are in receipt of benefits or have a low income.
