Work Progressing

Key phase in £17m project to construct one mile long sewer under Paisley streets is complete.

A key phase of Scottish Water’s major investment in its waste water infrastructure in Paisley to improve the water quality and natural environment in two local rivers has now been completed. 

Work is progressing on the £17m project which involves the construction of a one mile–long sewer under the streets of Paisley, and the installation of Combined Sewer Overflows (CSOs) in the town centre. 

So far, 6 of the15 shafts required for the project have been constructed and a Microtunnel Boring Machine (MTBM) has excavated the route in between those shafts. The CSO at Causeyside Street/Forbes Place, opposite Dunn Square, has now been completed. 

Scottish Water contractors Amey are constructing the large diameter interceptor sewer which starts at Bridge Street car park and makes its way across the Watermill Hotel car park and Lonend before going along Saucel Street, beneath Saucelhill Park and the railway line near Canal Street Station, Espedair Street, Rowan Street and Kilncroft Lane/Neilston Road. 

Once completed, the project will substantially reduce the frequency of spills from the sewer network into the Espedair Burn and White Cart Water in storm conditions, improving the river water quality in the two watercourses and, in turn, the River Clyde. 

Ruaridh MacGregor, Scottish Water Corporate Affairs Regional Manager, said: “The technology we’re using on this project is less disruptive than more traditional methods of excavation and well suited to the urban environment we’re working in. 

“The route of the sewer tunnel was chosen to minimise any disruption to local residents, road users and businesses. Whilst we appreciate that the work has however still been disruptive for some, once completed, this investment is going to provide substantial benefits for the local environment. 

He added: “Road traffic management will continue as the project progresses and we’d like to thank local residents, businesses and commuters for their patience.” 

As part of the legacy for this project and a ‘thank you’ to the local community for their patience throughout the work, Scottish Water and its partners carried out footpath and tree clearing at Jenny’s Well Nature Reserve. Not far from Paisley town centre, the reserve runs along the White Cart Water and provides a peaceful haven for wildlife. 

This Paisley investment is the biggest Scottish Water has ever made in Renfrewshire and forms part of the utility’s £250m, five-year programme of work, launched in 2013, to improve river water quality and the natural environment and tackle flooding across the Greater Glasgow area.
