Welsh Water complete £8 million wastewater upgrade in Cardiff


24 November 2021

Dŵr Cymru Welsh Water have completed their £8 million wastewater upgrade in the north of Cardiff. This investment work will help increase the sewer network capacity and improve the quality of the water released back into the environment.

The work, which got underway in June 2020, involved replacing, cleaning and relining sections of the wastewater pipe between Hailey Park and Tongwynlais. The company replaced and relined more than 800 meters of sewer pipes and cleaned 733 meters of pipe. A total of 670 tonnes of debris was removed during the work – that’s about four times as heavy as a house.

Due to the location of some of the sewer pipes, the company worked closely with contractors Morgan Sindall, Cardiff Council, Transport for Wales and local community groups to plan and deliver the work.

Welsh Water’s Project Manager, Andrew Davies, said: "We’re pleased to announce that our investment work between Hailey Park and Tongwynlais is now complete. This investment reflects our commitment to reinvest profits directly for the benefit of our customers and the communities that we service, helping to ensure we provide a first-class wastewater service and protect our precious environment.

“We understand that our work may have caused some inconvenience at times, so we really do appreciate the patience and understanding shown to us by local residents and would like to thank them for bearing with us while we completed our work."

As part of this investment, the company awarded £500 to the Tongwynlais Athletic Football Club (AFC) to support with the growth of the club and gifted several team shelters to help provide shelter during bad weather conditions.

Gareth Morgan, treasurer of Tongwynlais AFC, said: "As treasurer of Tongwynlais AFC I would like to acknowledge the magnificent support Welsh Water have given the club as we aim to grow in very challenging times. The support will enable us to purchase much needed equipment for the infrastructure of the club such as corner flags, and training tops as well as more secure locks for our changing rooms. Thank you to all at Welsh Water for your support and donations."
