CPC Civils, as Principal Contractor, are currently undertaking the installation and renewal of 80m of District Heating pipework from Norfolk Street to Flat Street in Sheffield. The works are essential in maintaining the 44km long Sheffield District Energy Network which has been in operation since 1988.
The integrity of heat distribution pipes, which distribute pressurized hot water at 110°C, are key to ensure that the district heating scheme can deliver the low carbon energy to the communities and businesses in the city.
The pipeline runs beneath Arundel Gate through a tunnel of approximately 40m in length meaning replacement of the pipework would be extremely time consuming and expensive. The solution was to reline the pipework with a Carbon Fiber liner, CarboSeal®. A new product for District Heating pipelines and the site was the first installation of the product in the UK. CPC Civils and Colus attended training in Sweden to learn how to install the liner and subsequently installed the product successfully on the District Heating Network in Sheffield.
Andreas Martsman, Managing Director of Carboseal said:
“We are grateful for Veolia UK choosing to be first in the UK to install CarboSeal®. Synergi did a great job on the design work and it was a pleasure to train and work with CPC Civils and Colus to realise this install. Now we are well set up for helping the UK refurbishing their District Heating Networks in a fast, simple and sustainable way.”
Carbon lining, which has a minimal impact on system operation, now provides long term security and longevity of the pipe system as the material has exactly the same expansion, contraction, strength and durability properties as a steel pipe. The inherent strength of carbon lining makes it self-supporting and is designed to completely take over the workload of the host pipe, supporting the weight of the system water, and maintaining the integrity of the system.
There are many benefits to lining as listed below:
- Minimal Excavation required to install the liner. A launch and reception pit are all that is required.
- No excessive welding or weak spots within the network.
- No disruption to roads with closures or complex traffic management requirements.
- Design life is in excess of Steel Pipes (approximately 35 years).
- Cost savings based on alternative methods.
- Fast install process meaning disruption to the network is greatly reduced.
- Reduction in heavy civil engineering can have up to an 80% reduction in CO2 emissions during the construction process.
CPC Civils are the only contractor in the UK approved to install the Carboseal® product.
“We have formed not only fantastic working relationships but also lasting friendships. I would not hesitate in working with CPC Civils again, as they are without question the most helpful, skilful and friendly partner you could wish for, and I look forward to developing this already fruitful relationship further in the coming years.”
“Well done Wayne Barron, John Donnellan, Pat Concannon, Conall Cunningham and the CPC team. We had a phone call from Paul Dennison (Severn Trent Water), he and his colleagues are very complimentary of the work at Kingsholm. They praised the tidiness, the setup, the workforce attitude and the standard of workmanship completed at the site ”
“I could sit and write multiple examples where CPC and your team have, in my opinion, gone above and beyond what would normally be expected. I would however just like to say that this ongoing attitude, and excellent working relationship, has not only aided Centro in 2 current Metro extensions it has also given me huge confidence in the planning of 5 further Metro extensions. It’s also made my job very enjoyable”
“Interesting weekend replacing a 12m length of sewer that had collapsed underneath a railway line in Bloxwich. Within 48 hours the team were able to diagnose the problem and work up a design and complete the repair. Amazing collaboration between STW, Amey, CPC and Network Rail”
Carillion have been impressed by the high safety, quality and overall standards of your on-site Supervision, quality of workmanship and the ability to complete the works in line with the agreed programme. It has been a pleasure working with the team from CPC Civils on the Lower Don Valley Flood Defence Project and we welcome working with them once more on future successful projects

“A big thank you to the CPC team regarding the Achilles Audit undertaken on site – keep up the good work!”
“First and foremost, thanks to CPC for all the help and advice over the past 12 months. To each and every tradesman, your engineer, steelworkers, shuttering team, stone masons etc, a big thank you. At the risk of embarrassing anyone, we found everyone polite and obliging”
“I would like to thank all those who have worked on this project, especially the men who have been on site every day. In the 8 months of the work we have been kept fully informed at all times of the progress and all those concerned with the work have gone out of their way to be courteous and helpful.”

“I am pleased to tell you that I have been asked by the Project Board to express their appreciation for the way you and your subcontractors have undertaken the District Heating Main Extension contract to date. We appreciate the professional manner in which you have proceeded with the planning and construction of the project despite the uncertain caused by delays in funding approval and agreements with landowners. The Board consider that your working methods, attention to detail, project management and health & saftey are excellent.”
“I would like to take this opportunity to thank you for the wonderful opportunity that you provided my students with last week. The effort, time and organisation that went into planning the visit is much appreciated. The resources you have given us are superb and will allow the students to really develop their understanding of flood management in their local area.”
