Paisley project helping to improve three rivers

The £750,000 investment involved the installation of extra capacity in Scottish Water’s waste water infrastructure to help reduce the risk of discharges of waste water in storm conditions to the Hawkhead Burn, which flows into the White Cart Water and the Clyde. Contractors George Leslie, working for Scottish Water, installed 520 metres of new sewer in the Rowan Street area to increase capacity and reduce the risk of a Combined Sewer Overflow (CSO) in the street discharging to the watercourse. The project, which started in June 2014, is part Scottish Water’s major investment in the Greater Glasgow area’s waste water infrastructure.

The overall £250m, five-year investment, the biggest in the Greater Glasgow area’s waste water network in more than a century, will improve river water quality and the natural environment of the Clyde and its tributaries, enable the area to grow and develop, alleviate sewer flooding and deal with the effects of increased rainfall and climate change. The new 600mm diameter sewer in Rowan Street, Paisley was installed from its junction with Thrushcraig Crescent to its junction with Lochfield Drive. The increased capacity was required to reduce the risk of storm discharges and will contribute to an improvement in the water quality in the watercourses. The work required some road traffic management and there were lane closures on sections of Rowan Street at different times during the project.

Sections of the new sewer are more than six metres deep so large construction plant, including wheel-mounted excavators and rock breakers, was used. The project took longer than we had anticipated due to the type of rock which had to be excavated. Mrs Joanna Peebles, Scottish Water’s regional communities team manager, said: “We are delighted to have completed this very important environmental improvement project in Paisley. “Scottish Water’s investment in the area will deliver major environmental benefits for years to come and we are sure that local residents will welcome the completion of the project. “We apologise for any inconvenience caused to residents and road-users during our work, including the rock excavation, and thank them for their patience and understanding. “We are sure that the long-term benefits this investment will deliver will far out-weigh any short-term inconvenience during the project.”
