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?

Our work is taking place between Rhymney and Bargoed, and within the Deri area. Our work started in Rhymney around the beginning of June 2020, and as we work our way through the Rhymney Valley we will ensure that we keep all residents and businesses informed.  Our work is being carried out by Lewis Civil Engineering, and as long as everything goes to plan we aim to have it completed by June 2022.

Areas that will benefit from the investment will include Rhymney, Pontlottyn, New Tredegar and Deri. 


Street names: Merthyr Road, Rhymney
Start date: June 2020
Expected completion date: September 2020
Additional information: In order to carry out the work safely, multiphase traffic lights are in place to ensure the safety of the residents as well as our work force. The pipe laying activity on this section of road will be is planned to be completed towards the end of September. The new pipe will distribute the fresh, clean drinking water from the new water mains to the customers tap. 


Street names: Merchant Street  
Start date: June 2020
Expected completion date: October 2020
Additional information: In order to carry the work out safely, there will be multiphase traffic lights in place. We will try to keep the working area to a minimum and maintain as much access as possible for the residents. The work will be carried out from the junction of Heol Evans Wynn and down as far as the junction of Brewer Street. We anticipate this section of work will be completed towards the end of September.  


Street names: Upper High Street and High Street
Start date: July 2020
Expected completion date: September 2020
Additional information: As part of the £10 million pound investment into the water network, we are laying a brand new water main along Upper High Street and High Street. In order for the work to be carried out as quickly and as safely as possible, a road closure will be in place. We understand that this is a residential area, therefore, access will still be available for residents in and out of the High Street and surrounding streets. The work is being carried out in sections along the road and we anticipate that we will reach the junction of Church Street and Lawn Terrace towards the end of September 2020.

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.
