en.Wedoany.com Reported - UK-based Esh-Stantec has recently completed a sewer pipe lining rehabilitation project within Auckland Park for Northumbrian Water Group, as part of a broader sewer network upgrade scheme.

This lining rehabilitation reinforced and protected a total of 1,200 metres of sewer pipes with diameters of 225mm and 300mm. The works were organised into two phases. Phase one involved setting up a 1,000-metre overland pumping system to divert flows from 11 sewer sections above ground, followed by high-pressure jetting to clean the pipes and descaling using pipe wall cutters. Vacuum tankers, remote reels, UV curing equipment, winches, towable generators, and various cutting tools were deployed on site, with tracked front-loading equipment used to protect the ground and surrounding woodland environment. The first 11 sewer sections were lined within 21 days.

Phase two saw the dismantling of the overland pumping system—including two 6-inch pumps, 8-inch overland polypropylene pipes, and multiple road ramps—with all equipment redeployed to install an 850-metre overland pumping system, completing the cleaning and lining of the final six pipe sections. The road ramps were used to ensure safe public access and access for a local farmer to the park.

The sewer network originates in a field adjacent to the A688 road, runs through Bishop Auckland Golf Course, and passes through a protected woodland within Auckland Park. The construction team operated within a conservation-status woodland environment, strictly following recommendations from ecological surveys, and conducted on-site patrols throughout the process, confirming no impact on surrounding wildlife. To complete the cleaning work, the team positioned vacuum tankers at varying distances from the work area, up to 750 metres away at some points, and transported up to three remote reels in convoy using trucks. For some of the most inaccessible pipe sections, suction hoses up to 1,000 metres long were used. The UV curing lining equipment was also offloaded and manually carried into the park.

During CCTV inspections, the team identified several additional tasks, including sections of cast iron pipe and a 10-metre-long concrete blockage within one pipe joint. After removal using portable cutting tools and specialised ultra-high-pressure jetting equipment, the liner was successfully installed. Pipe lining is a trenchless rehabilitation method offering a guaranteed service life of at least 50 years, strengthening the pipe, preventing root ingress and further deterioration, and improving flow capacity to prevent flooding.
