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
- Delivered by Caledonia Water Alliance (CWA)
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
Phase Two
A giant crane is needed to lift the lining into place
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.
The work is part of an £11million investment project
Ferry Road has reopened
Update April 2026
Work on the third phase, between Crofton Way and the junction with Laymoor Avenue began on Monday 29 September 2025.
The new lining has been installed and pressure testing of the newly lined pipe has been successfully completed. It is now carrying the high pressure flows of wastewater.
The temporary overland pipeline will be dismantled and the area fully reinstated with all work expected to be completed by the end of May.
A two-week road closure will be required on Crofton Way from Monday 13 April to allow material to be safely removed from site.
A specialist landscaping contractor will carry out the reinstatement of the ground at the access pits, where any hedging and trees that have been removed will be replaced.
It may be necessary to fence off some areas for turfing or seeding to allow the grass to become established. The footpath at the access pit at Laymoor Avenue will be carried out by a surfacing contractor.
We are extremely grateful to the community for their continued patience, understanding and cooperation while we deliver this much needed investment project.
