OVERVIEW

The development of a new RWPS on the west bank of Loch Ness formed part of Scottish Waters Regional Improvement Scheme. The scheme would provide an upgrade to improve the water quality and system resilience to the area. As part of the Scottish Water’s Supply Chain, IUS delivers contestable connections as an Independent Connections Provider. Therefore, IUS was appointed to design, procure and deliver the new electrical supply to operate this new pumping station.

DESCRIPTION

The works necessitated the installation of new H-Poles adjacent to the existing Scottish Power Energy Networks (SSEN) overhead line. These Hpoles would accommodate the installation of a 33,000/433V, 200kVA pole mounted transformer (PMT) and associated components. From the LV side of the PMT, a LV cable was laid to the new RWPS kiosk, terminating in a cutout beneath the installed current transformer metering panel. 

The feeder route necessitated a road crossing. To minimize disruption to traffic flow on the A82, the road crossing was undertaken by directional drilling.

Extensive engagement with SSEN was maintained throughout the duration of the works to ensure full compliance with their adoptable standards. On completion the substation was energised and the RWPS is now in full operation.

IUS undertook full design duties and operated as Principal Contractor (PC) for all our site works, liaising closely with Scottish Water’s own PC for the main development.
