Scottish Water has gone out to tender with a contract for pumping station construction work for its Dalmuir Strategic Flow Transfer Project worth up to £40 million.
The Dalmuir Strategic Flow Transfer Project involves detailed design and construction for the provision of new pumps and rising mains to transfer flows from the existing Partick pumping station to the inlet works at Shieldhall WWTW.
The new arrangement at the pumping station will transfer up to around 1 900 litres per second. The rising mains required are proposed as twin 900 mm diameter over a length of 4,3 km. and will involve tunnelled crossings of the River Kelvin and Clyde as well as tunnelled crossings of the A814 Road and the Glasgow to Oban Railway.
The Glasgow Underground and Clyde Tunnel are also crossed in open cut sections of the work. Process upgrading is expected to be required at Shieldhall WWTW in the form of additional aeration within existing tanks in conjunction with automation at existing storm tanks and control amendments to existing screw pumps.
The work will include replacement of submersible pumps, refurbishment of existing storm tanks with automation of penstocks and tank scrapers, refurbishment of screw pumps controls and upgrading of existing aeration capability.
Estimated value of the work at this stage is between £30 million to £40 million. Time limit for receipt of tenders or requests to participate is 18th August.
