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.

What’s next?

Street Names: Groes-Faen Terrace to New Road, Deri
Start Date: Autumn 2022
Expected Completion Date:Spring 2023
Additional Information: We are installing a brand-new water pipe through an existing water pipe. With this innovative method, we’ll only need to work in smaller sections along the route, meaning this will have less disruption to our customers and motorists.

To carry out the work safely, we will put temporary traffic lights in place which will move along the working route with us.

We’ll be making brand new, individual water connections to houses along Groes-Faen Terrace and New Road. Whilst this is happening, we’ll have the temporary water pipe in place above ground, meaning that there shouldn’t be any interruption to the water supply.

We’ll be sure to give our customers plenty of notice if we need to work outside of their home, and our contractors, Lewis CE, will work around customers’ plans where possible and will always maintain access to their property.

Traffic management plan

We spend a lot of time planning our work to make sure it causes the least disruption possible. There will be times when we do need to work outside of properties, 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 Jun 2020, we have gifted over £5,000 to the local foodbank and over £7,000 to community groups in the Rhymney Valley. The fund 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.
