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 February 2026
Work on the third phase, between Crofton Way and the junction with Laymoor Avenue began on Monday 29 September 2025.
A temporary overland pipe has been set up and is now carrying flows so we can 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.
The work will be carried out in two phases during the week beginning Monday 9 February 2026.
The liner will be fed into the sewer pipe where it will be heated before the curing process starts, creating a new inner wall to the existing pipe. Floodlights will be needed for the working area but these will be positioned away from peoples homes.
We plan to begin at 8am and should be finished by 6pm although depending on progress we may need to extend until 10pm on Tuesday, Wednesday and Thursday.
Phase 1 – Crofton Way to Laymoor Walk
- Mon 9th Feb 8am – 6pm (preparation work and delivery of liner material)
- Tue 10th Feb 8am – 6pm (installation of liner and curing. Depending on earlier progress, work may need to continue up to 10pm)
- Wed 11th Feb 8am – 6pm (removal of equipment from first lining operation site to next - work may need to continue up to 10pm)
Phase 2 - Laymoor Walk and Laymoor Avenue
- Wed 11th Feb 8am – 6pm (removal of equipment from first lining operation site to next - work may need to continue up to 10pm)
- Thurs 12th Feb 8am – 6pm (installation of liner and curing. Depending on earlier progress, work may need to continue up to 10pm)
- Fri 13th Feb 8am – 6pm (removal of lining equipment and camera survey of both sections of newly installed lining to commence)
Once completed, pressure testing of the pipe will begin, but this will be carried out during normal working hours.
We are extremely grateful to the community for their continued patience, understanding and cooperation while we deliver this much needed investment project.
