Scottish Water is upgrading nearly a kilometre of a vital strategic sewer main running between Renfrew and the Shieldhall Waste Water Treatment Works in Glasgow.

Work began at the beginning of February 2024.

King's Inch Burst

There have been a number of bursts over recent months.

What We Are Doing

We are relining nearly a kilometre of 700mm sewer running from the pumping station at Renfrew to Shieldhall Waste Water Treatment Works in Glasgow.

A temporary overland pipe will be constructed to carry the flows while the existing underground sewer is lined through access pits located at strategic points along the route.

The work is being delivered by our alliance partner Caledonia Water Alliance (CWA) and their specialist contractors who have a proven track record for delivering work on this scale.

The sewer will be relined using strategic access pits

Why We Are Doing It

This section of sewer is prone to bursts because of its age and condition. A number of recent incidents caused disruption to local residents and saw the Paterson Park Association allotments flooded several times in a matter of months.

We have fast-tracked the project to address the vulnerability of the network and to protect the environment and customers

The works will provide improved resilience and drastically reduce the chance of future bursts along the relined section.

Phase Two

A giant crane is needed to lift the lining into place

Update June 2025

Work is well underway on the second phase of the project, to reline the section of rising sewer main from North Lodge Road Pumping Station to Ferry Road in Renfrew.

A temporary overland pipe from North Lodge Road pumping station is now carrying flows while the existing underground pipe is relined through access pits at strategic points along the route.

We have been carrying out lining work of the rising main from the access pit on Simons Crescent to the access pit in the area behind Meadow Lane, and from Simons Crescent to the access put on Ferry Road.

The process involves heating the liner, feeding it into the pipe by crane, then allowing it to cure creating a new inner wall.

Ferry Road remains closed between King’s Inch Road and Campbell Street.

We have been working closely with customers and local businesses to ensure the work has as little impact as possible and we will continue to keep them informed at every stage.

Bus routes in the area are subject to alternative arrangements with a shuttle bus servicing King’s Inch Road. Details below:
