BRINGING THE quality of water supplied to the North of Scotland up to standard will cost over £1bn, according to North of Scotland Water (NoSWA) programme manager Mark Connelly.
Speaking to the Dundee area branch last month, Connelly said NoSWA has identified 240 water quality problems in its area, which extends up the east side of Scotland from the Forth estuary to the Shetlands. Action to meet either current or anticipated legislation will see the present budget of £180M augmented by projects totalling £900M.
With traditional procurement too inefficient and slow, and PFI and PPP schemes having too long a lead-in time, NoSWA will procure the work by partnering with selected consultants and contractors.
Early involvement of joint teams in the design and planning of project works should lead to significant savings, explained Connelly.
The approach has already paid off on the North Coast Regional Scheme, he said, where partnering has shaved £3.5M off the original estimate of £32M.
The scheme, covering 11 water treatment works constructed in the 1950s and 1960s and serving 13,000 customers from Wick to Tongue, involves the laying of 80km of new pipeline to a new source of raw water, Loch Calder.
The savings have come through value engineering and by cutting down on leakage and optimising the pipe route, and take into account operational risks and whole life costs. The scheme should be completed by 2003.
