Scottish Water is getting ready to start work on the third phase of an £11.5 million investment to upgrade a vital strategic rising sewer main between Renfrew and Glasgow - a temporary pipeline will once again be used to carry flows while the underground rising sewer main is relined.

The second phase of the project required the closure of Ferry Road at King’s Inch Road to allow a temporary pipeline to connect into the underground pipe. Final reinstatement is being carried out and the road was due to reopen on Friday 12 September 2025.

Next week work will get underway on Monday 29 September to upgrade a section of pipe running underneath King’s Inch Road between Crofton Way and Laymoor Avenue.

Nearly a mile has already been relined along King’s Inch Road to the North Lodge pumping station which pumps pressurised waste water to the Shieldhall treatment works.

A temporary pipeline will be set up to carry the flows from the pumping station. Access pits will then be excavated at strategic points to allow the lining material to be fed down the pipe.

Nathan Wield, Scottish Water’s Regional Treatment Manager said:

“We will be using a different, less intrusive method to draw the liner through the pipe than the first two phases.

“There won’t be any need for scaffolding so we can carry out the work at ground level although a lane closure will be needed on King’s Inch Road.

“This section of pipe has been prone to bursts quite recently so once completed the relined rising main will be much more resilient and far less likely to fail.”

Scottish Water is investing record levels – around a billion pounds a year – to repair, renew and replace vital assets.

The work is being delivered by the public utility’s alliance partner Caledonia Water Alliance (CWA) and their specialist contractors and is expected to be completed by March 2026.
