King's Inch Road Sewer Upgrade

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.

The section running underneath King's Inch Road will be relined using access pits at key locations while a temporary overland pipeline is used to divert flows.

Work began at the beginning of February 2024 and is expected to take approximately 10 months to complete.

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.

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.

Update June 2024

Our delivery partner Caledonia Water Alliance (CWA) is set to begin the lining works on Tuesday 2nd July, with the first sections (near to the junction of Kings Inch Road and Andrew Avenue, and Kings Inch Road and Crofton Way) expected to take around 7 days for completion.

The lining process involves a few different stages; a liner is fed into the existing pipe from access pits which have been excavated at different points along Kings Inch Road. It is then heated and cures inside the existing pipe to create a new inner wall.

Lining is a continuous process and therefore requires the team to work longer hours to ensure everything goes smoothly. Preparatory works will be carried out on the Tuesday, with the lining works beginning from around 8am the following day. Overnight working will be required on Wednesday 3rd July and Thursday 4th July.

The access pits for the lining works are close to residential properties and we have notified all of the customers likely to be affected. We have been clear that while noise is unavoidable, the team will do their best to keep any noise to a minimum. Lighting is required for the overnight operations, but the team will position the lights to ensure they point into the work area and away from windows.

We thank all local residents for their patience and understanding while we carry out these essential works.

A temporary overland pipe is in operation to handle flows while the existing underground sewer is relined.

Running along King's Inch Road between Ferry Road and Crofton way, the bypass will significantly reduce the risk of future bursts while work on the existing sewer is carried out.

Andrew Avenue and Crofton Way remain closed to vehicles although pedestrian access is being maintained.
