Case Studies
Dodburn Water Network Improvements
The Dodburn water network improvements were part of a wider project to improve the water quality from Roberton Water Treatment Works around the Scottish Borders town of Hawick.
The work comprised a new raw-water inlet main, and a new raw-water pumping station at Acreknowe, together with large and small diameter distribution mains. An interesting feature was the helicopter-access, which provided the most economical method of pipe delivery to much of the remoter stretches.
Two large bore mains were laid from the water treatment works, for potable water from Roberton to Crumhaughill service reservoir situated on the outskirts of Hawick, and for raw water from Acreknowe pumping station.
The work also included 9.6km of small-bore distribution main, with multiple domestic connections which branched off from Crumhaughill and terminated at Dodburn.
Pipeline Summary:
315mm & 355mm twin track HPPE - 7.3km
90mm Alkothene single track - 4.1km
315 HPPE single track - 3.3km
63mm Alkothene single track - 5.5km
355 HPPE single track - 1.5km
160mm HPPE slip lining of 21” cast iron - 2.8km
This Design & Build contract was undertaken for Scottish Water Solutions by Biwater Leslie Joint Venture, with Faber Maunsell / Farrer Consultants as designers.
