Project Overview

This £17m project 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 and is expected to be completed this autumn.

The route of the pipe started at Bridge Street car park and go 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. 

This investment will substantially reduce the frequency of spills from the sewer network into the Espedair Burn and White Cart Water in storm conditions. It is part of the wider investment in Greater Glasgow which will improve river water quality and the natural environment and tackle flooding.
