King's Inch Road Sewer Upgrade

Project Overview

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.

At a Glance

Multi-million-pound investment
Nearly a kilometre of sewer upgraded

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.

Nearly a kilometre of temporary pipe has been laid

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 September 2025

Work 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 has now been completed.

Work on the third phase, between Crofton Way and the junction with Laymoor Avenue will start on Monday 29 September 2025 where we will again be setting up a temporary overland pipe to carry flows while we work on the underground rising sewer main.

Access pits at strategic locations will be excavated but we will be using a slightly less intrusive method to insert the liner that will not require scaffolding.

We will need to close the inside lane of King’s Inch Road and there will be some changes to pedestrian access so we would ask people to follow all signs.

We are extremely grateful to the community for their continued patience, understanding and cooperation while we deliver this much needed investment project.
