Water Supplies to Clydach Vale, Pontypridd, Treorchy, Tonypandy and Pentre

First of all can I apologise for the loss of water supply as a result of the major incident we have had on one of our large diameter water mains at Cilfynydd, near Pontypridd. The main in question is a 31"/ 850 mm trunk main which carries very large volumes of water and is effectively a 'transmission' main to support supplies to a wide geographical area. This is why as a result of the incident communities in the Rhonndda and Church Village for example were also affected.These type of mains fulfil a vital role in keeping our smaller mains which serve customers directly full and delivering water at the right pressure. Repairing these type of mains is a major task and because of the operating pressure carries significant safety risks and we have to take this into account as a key priority to protect our people and contractors carrying out the repair.

I am also sorry that deliveries of bottled water to distribution points was not as effective as we would have liked and there are lessons to be learned from this about how we carry out this type of support to customers in future. We did however, successfully deliver bottled water to over 600 vulnerable customers, such as those with medical conditions and the elderly which I hope you will agree were the highest priority in the circumstances.

By early this morning supplies are returning to normal for the majority of our customers , but we are experiencing some 'air locks' in the system , particularly in the Clydach Vale area and we are focusing on on this as a matter of urgency.

If you are currently experiencing any further problems do not hesitate to contact us or speak to us using live chat.

Thank you

Peter Perry

Chief Operating Officer

Understanding how Welsh Water impacts on the wider environment and the actions we can take to minimise any adverse effects is a key objective for the business.

Our industry interacts with the environment and community in a way that few others do. By supplying clean water and by collecting and treating wastewater, our role is to help to meet the public health needs of today and, through careful stewardship of the associated infrastructure, for future generations.

The processes we use to treat water and wastewater have a direct impact on the environment. This can be in terms of the use of primary resources such as energy, water and chemicals or in terms of the discharges to water (fresh and coastal), generation of waste (particularly sludge), the emissions to air (odours and greenhouse gases) and potential disturbance or harm to the environment.

We are committed to identifying and accounting for the environmental implications of all of our activities, and for recognising and considering opportunities for economically sustainable environmental benefit.
