Cardiff Llanishen and surrounding areas

We’re investing £7.8 million to improve the water network in Llanishen and the surrounding areas of Cardiff. This will help continue to provide our customers in the area with a safe, reliable supply of clean drinking water for decades to come.

The work will help to ensure security of supply to our customers and to alleviate issues with loss of supply or low water pressure currently experienced by some customers in the area.

What does this work involve?

Some of our pipes that provide customers with their morning shower and cups of tea are over 100 years old. Over time natural deposits can build up inside the pipes and slow the flow of the water. While these deposits are not harmful, every now and then we need to clear the pipes to keep the water running freely.

With some parts of the network nearing the end of its operational life, the investment in this area will see us replace 3.7 km of pipework.

Where will the work take place?

The work will begin in early September 2023 and we expect to be completed by October 2024.

You can see where we’ll be working below:

If we do need to work outside of your property, we’ll be sure to contact you directly closer to the time and will be updating the ‘In Your Area’ section of our website with any specific traffic management plans.

We’ll have a compound and welfare unit situated opposite Peppermint Park for the duration of the work.

Your water

Throughout most of the work there should be no interruptions to your supply. However, due to the nature of this work, it might be necessary for us to turn off your water supply for a short period of time (up to 3 hours). If we need to do this, we will let you know with plenty of notice.
