Yaddlethorpe STW case study

Yaddlethorpe STW Upgrade

CPC Civils were contracted to move the point at which treated water is put back into the environment from Bottesford Beck to the larger River Trent.

Yaddlethorpe Sewage Treatment Works – Project Overview

As part of a programme of upgrades at Yaddlethorpe Sewage Treatment Works, CPC Civils would install pipework to divert processed water to a new outlet.

The installation will enable transfer of treated, recycled water to the River Trent rather than Bottesford Beck.

Yaddlethorpe Sewage Treatment Works – Construction Specifics

To complete the project CPC Civils would:

  • Install 3.7km of 900 DI pipework from Yaddlethorpe Sewage Treatment Works to an in-situ concrete outfall on the banks of River Trent.
  • Construct 600m2 piling platform spanning onto existing East Butterwick High Street for a period of 6 weeks.
  • Install 140 Nr sheet piles ranging from 17m to 9m in length. This will form temporary flood defence, structure the cofferdam and provide structural support for the base and walls.
  • Undertake the removal of circa 250m3 of existing flood defence bund and river embankment to form temporary working platforms and provide access for the construction of the structure.
  • Install 9 tonnes of reinforcement.
  • Place 144m3 of ready mixed concrete.
  • Construct 2.5m deep in-situ concrete manhole chamber (MH1) for the pipework connection from Yaddlethorpe STW and the outfall.
  • Complete installation of concrete bed and surround 900mm dia ductile iron pipework linking the outfall to MH1 on the east side of Butterwick High Street.
  • Undertake install of various metal works from access stairs to security grilles to hand-railing.
  • Cut down and remove circa 19 tonnes of redundant sheet piles.
  • Remove temporary working platform and reinstate circa 40m length of flood bund and embankment.
  • Re-seed circa 700m2 of flood bund and embankment.

Yaddlethorpe Sewage Treatment Works – Project Challenges

Successfully completing the project would require CPC Civils to overcome a number of challenges including:

  • The temporary sheet pile flood defence on the banks of River Trent being located within a small area adjacent to residential properties.
  • Needing to remove the flood bund and construct a 80m2 concrete structure adjacent to a live water course.
  • Completing works while also maintaining public access through, and maintaining health and safety in the work area.

Yaddlethorpe Sewage Treatment Works – Project Outcomes and Values

CPC Civils would begin work on this project in August 2022 and are set to complete in April 2025.

When complete the project will boost capacity and ensure that the waterway operations are in top condition.

The upgrade will also improve the condition of the Bottesford Beck which runs past the treatment works and into the Trent at East Butterwick.

Currently the processed water is pumping directly into the Bottesford Beck which is a much smaller water course. However the Bottesford Beck will radically benefit from the water discharging directly into the larger water course of the Trent.

The area is a popular spot for the general public to walk.  The upgrading of the waterways system realising a network that operates predominantly underground will improve conditions for the environment.

“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.”

“Thanks to the installation teams from JP Concrete and CPC Civils  for a safe and excellent quality installation, very good job.”

“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.”
