Water Supply & Pipeline Work

Glendevon Raw Water System Repair Works

Glendevon Water Treatment Works provides the principal supply of treated water to the greater part of Fife and this project was to carry out essential repairs, maintenance and upgrading work on the raw water feed to the treatment works from Glendevon Reservoir high up in the Ochil Hills.

The main areas of work included pipe-bridge repairs, mains replacement and upgrading and stabilisation of areas of slope slippage.

The work on five pipe-bridges entailed firstly the removal of extensive overgrown vegetation, which enabled blast cleaning of the pipework to removal the existing pipe coating with the subsequent application of a new protective system. These works work carried out under a fully-scaffolded, encapsulation containment system to prevent any river pollution.

Ground stabilisation at Glenshirup involved the temporary diversion of the river to divert flows away from the pipeline which has suffered a degree of undermining, cutting out around sections of pipework and installing pipe supports and protecting the pipeline with rockfill to stabilise the area and prevent further erosion.

The mains replacement work comprised of laying a 240m section of new, 400mm diameter HPPE pipe, including a road crossing and tie-in connections at either end, together with slip-lining a further 120m of the existing main.
