Rhymney Bargoed

We’re investing nearly £10 million to improve the quality of water in the Rhymney Valley to ensure we continue to provide our customers in the area with a safe, reliable supply of clean drinking water for decades to come.

Why are we doing this?

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.

Our plan is to invest around £10 million in the water network in the area and we want to let you know what that means for you.

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.

Most customers will not be affected by the work and will probably not even notice the work being done, but we will write to any customers that may be affected with all the information they will need.

With some parts of the network nearing the end of its operational life, the investment in this area will see around 17km of water mains either replaced or abandoned. That is the equivalent to the length of almost 186 football pitches.

Where will the work take place?

This work will take place between Rhymney and Bargoed, and within the Deri area. Our work started in Rhymney and Pontlottyn in June 2020 and we will continue to keep all residents and businesses updated throughout the duration of this work. Our work will be undertaken by Lewis Civil Engineering and as long as everything goes to plan it will be completed in spring of 2023.

Areas that will benefit from the investment will include Rhymney, Pontlottyn, New Tredegar and Deri. Here’s an overview of where we’ll be working in the coming months:


Street Names: Troedrhiwfuwch to New Tredegar along the A469
Start date: August 2021
Expected completion date: Early 2022
Additional information: We are installing a brand-new water pipe through an existing water pipe. To carry out the work safely, traffic lights will be in place to ensure the safety of the residents as well as our work force.

Street names: From Rhymney High Street to Factory Rd, Bargoed
Start date: August 2021
Expected completion date: Early 2022
Additional information: We have a team who are currently carrying out abandonment work in the area. This means that they are abandoning the original water pipe and making sure the brand-new water is ready for use.

Street names: Brithdir pipe bridge-over Rhymney River
Start date: August 2021
Expected completion date: Work is currently on hold
Additional information: We started work on the water pipe that is currently above ground, across Rhymney River in Brithdir. Due to unforeseen issues which has required changes to the design, work is currently on hold until early next year. Further updates will be confirmed as soon as the design process is finalised.

As our work progresses towards New Tredegar, we will update this page with further information.

Traffic management plan

We spend a lot of time planning our work to make sure it causes the least disruption possible. We’ve carefully planned the work here so that a lot of it doesn’t need to be carried out in the road. Instead, as much as we can, we will be laying the new pipes in land away from the main built up areas.

There will be times however when we do need to work in the road, and we may need to ask some people not to park where the work takes place. If this is the case, we’ll be sure to let you know in plenty of time. Please be assured that we’ll get the work in the roads done as quickly as we can.

The Community Fund

The Community Fund is a chance for communities to boost fundraising efforts for good causes in their area. Since 2018, 20 projects across Rhondda Cynon Taf have received funding. It has helped to support activities such as sports, music and arts equipment, office supplies, room hire, and providing mental health and wellbeing resources. Some of the funding has also been provided to nurseries, adult education classes and to groups to promote community engagement.

The Community Fund

If you live in an area where work is taking place – and you’re fundraising for projects to benefit the community – you could receive funding from Welsh Water up to a value of £1,000.
