Rainton Construction Makes Strong Progress on the Delivery of Water for Teeswork Site

Supplying a new potable industrial water network is a critical enabling requirement for development at Teesworks, including the delivery of Net Zero Teesside. Since June 2025, Rainton Construction has been delivering a complex, multi‑stage project to provide this essential infrastructure. The project has now reached a critical milestone with the installation of a GS8 valve chamber, a key component in the scheme’s infrastructure.

The programme began with extensive groundworks, delivered by MGL Earthworks, including enabling works to establish a safe working corridor around high‑risk assets. Legacy infrastructure that obstructed the route was removed during this phase, clearing the path for new water mains to be installed and allowing the project to progress safely.

Following completion of the enabling groundworks, Rainton Construction moved into the main civil engineering phase, installing a 600mm primary pipeline over a 1km stretch of the former brownfield site. This involved the excavation of bedding, along with the installation and joining of large‑diameter pipe sections and associated valves, forming the backbone of the new water network.

With the majority of the new pipework installed, the project reached a critical point as works progressed onto Stell Bridge. The bridge, spanning 45m, carries 3 existing above-ground water pipes that were in urgent need of structural repairs. Maintaining live water supplies throughout the works was an essential part of the project.

After establishing temporary works and a safe system of work, the bridge structure was inspected, with steel members repaired or replaced where necessary to improve longevity and durability. With the structure now future‑proofed, the team is turning its focus to the GS8 valve chamber works and the final connection of the water supply to Net Zero Teesside.

With new pipework now in place, the team can turn its attention to completing the wider water supply connection through road crossings and valve chamber works. This phase includes the removal of existing 600mm, 700mm and 900mm diameter steel and ductile iron pipework and fittings, which will be replaced with new ductile iron pipe. This is a crucial and complex stage of the programme marking the final major milestone to deliver the water.

Current activity is focused on upgrading a key valve pit, involving the removal of existing 600–700mm diameter pipework and the installation of new valves, chambers and thrust blocks.

This is a significant lifting operation that requires the installation of large components with strict tolerances. The works also demand careful coordination with adjacent Park and Ride activities and are being delivered in line with Northumbrian Water requirements, as the location acts as a primary control point for water supply across Teesworks.
