Normal water supplies were yesterday evening (Friday September 18)  restored to Scottish Water customers in South Uist, who experienced disruption resulting from an airlock affecting the intake water main to Stoneybridge water treatment works.

Scottish Water engineers worked through the night on Thursday, into Friday morning, to clear the airlock and restore normal production of drinking water at the site, which serves around 1600 customers across the south of the island, including Daliburgh and Lochboisdale.

While the supply from Loch Iarras to the water treatment works was interrupted, drinking water stored within the island network initially maintained supply to customers.  Customers experienced low water pressure or loss of water as storage reserves reduced, until water production was restored.

Water tankers were brought on to the island to allow supply to the water network to be supplemented by road if necessary – and these were used on Friday to speed up the restoration of supplies. A team from Scottish Water also distributed bottled water, targeting customers who have registered for additional support; and areas of the island which experienced the lengthiest disruption.

 A spokesperson for Scottish Water said on Friday: “We would like to apologise for the disruption to water supplies experienced by our customers served by Stoneybridge water treatment works last night and earlier today. We are grateful for their patience and support while our local team worked to restore normal service as quickly as possible.

“Supplies are now returning to normal across the island.  If customers experience discoloration or intermittent pressure following the restoration of supply, they should run their cold kitchen tap at half pressure until the supply returns to normal. If problems continue, they should contact us for further advice and assistance on 0800 077 8778.”

Customers who may need additional support if their water supply is interrupted, for example due to a medical condition, can join Scottish Water’s Priority Services Register either online by going to www.scottishwater.co.uk or by calling 0800 077 8778.
