Paisley in Renfrewshire, Scotland, is set to receive significant improvements to its wastewater infrastructure over the next two years in a major project designed to prevent flooding, enhance water quality and safeguard the local environment.

Scottish Water first announced a £250 million investment package for the wider Glasgow area three years ago. As part of the five-year package, it has just announced a new £17 million, mile-long sewer, in addition to two new combined sewer overflows for Paisley, which is home to over 75,000 people.

Leading public services provider Amey has been contracted to deliver the project, beginning with the installation of a 1.5m diameter interceptor sewer. This will be installed using a microtunnel boring machine [pictured] across the Paisley area.

Upon completion, it is anticipated that the sewer and overflows will help to substantially reduce the frequency of spills from the sewer network into local water courses, Espedair Burn and White Cart Water, during storm conditions. The works will also contribute to improvements in the local water supply, benefitting both local households and local wildlife.

Commenting on the news, Amey's Managing Director for Utilities, Kevin Fowlie, said: "We are excited to be delivering this vital infrastructure for the Paisley community. This landmark project marks the beginning of our involvement in the SR15 Managed Delivery Framework, which will see us deliver £100 million of projects for Scottish Water over the next five years."

Joanna Peebles, Scottish Water’s regional communities team manager, said:“This important project will significantly improve the environment on the White Cart and the Espedair Burn and, in turn, the River Clyde."

The Greater Glasgow area investment follows years of collaboration and studies by the Metropolitan Glasgow Strategic Drainage Partnership (MGSDP), whose partners include Scottish Water, the Scottish Environment Protection Agency (SEPA), Glasgow City Council, Renfrewshire Council and Scottish Canals.
