Work is progressing on our £17m project which involves the construction of a one mile–long sewer under the streets of Paisley. 

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. 

Key Project Facts:

  • Work started in October 2016 and is that is due for completion in early 2019

  • 15 shafts are being installed along the sewer route

  • 200 pipes will be installed

  • Two Tunnel Boring Machines will be used on the project; one of them 1200mm in diameter, the second 1500mm in diameter

  • Total tunnel length is 500 metres

Update: Summer 2018 (exact dates TBC)

  • Work in Paisley town centre is complete

  • Bridge Street car park has been returned to the council

  • Rowan Street will be closed for 8 months
