exclamation icon

Updated: 18:00 21 October 2020

We’ve now fixed the issue where customers were unable to pay for some of our applications online. However, customers who are paying for asset surveys/sewer traces or purchasing maps of public sewers may still have difficulty paying online.

We’re currently working hard to fix this issue. In the meantime, should you wish to make payment, please either utilise the BACS details on our quotation or send a cheque payable to Dŵr Cymru Welsh Water to Dŵr Cymru Welsh Water, PO Box 3146, Linea, Fortran Road, Cardiff, CF30 0EH.

We will continue to update this with any further news. Should you require any assistance, please do not hesitate to contact us on 0800 917 2652.

A notice to developer services customers

With the current situation across the UK regarding the spread of Covid-19 (coronavirus), we wanted to share an update on the steps we’ve been taking to prepare so we can protect the health and wellbeing of our colleagues, our customers and the communities we serve. It is now more important than ever that we continue to provide drinking water to customers to enable customers to follow public health guidelines and wash their hands.
As a company which provides an essential public service, we are acutely aware of the huge importance of maintaining our water and wastewater services during these unprecedented times. To achieve this, we have been running a dedicated Crisis Management Team for several weeks to strategically coordinate all our activity and ensure continuity of service.

What does this mean for you?
We're doing all we can to maintain services to our developer customers, while closely following the advice issued by public health agencies. For our developer services, this means an increasing number of our team are working from home. Currently, the impact on our services is limited. However, we realise the situation is rapidly changing, and are therefore closely monitoring events so we can take any required steps and keep customers updated. This might mean we have to start prioritising certain works, especially if they are field based.

Obviously this is a very challenging time but please be assured that we are – and will continue – to do everything we can to continue providing our essential services. We will provide you with further updates in due course, however should you have any queries in the meantime, please do not hesitate to contact us on or by ringing us on 0800 917 2652.
