The 70 residents of one of the most remote island communities in Britain – Fair Isle – are benefiting from an innovative Scottish Water project

Posted: Wednesday 14th December 2011

The island is only a few square miles in size and lies 25 miles south-west of the southern tip of mainland Shetland and 30 miles north-east of the nearest of the Orkney islands. The ferry from Lerwick takes four and a half hours.

The drinking water supply on Fair Isle is produced using two boreholes, one of which had been identified for some maintenance to remove a build up of naturally occurring minerals. Drinking water quality in Scotland is at a record high and Scottish Water’s investment is designed to keep it that way for all customers, no matter how rural or remote.

For the work a specialist technique called “AirBurst” was used, provided by Cirrus, the only company in the UK able to carry it out. High pressure air is used to dislodge the built-up material and this is recovered from the borehole water and filtered out, leaving a clean borehole and clean water.

The alternative would have taken longer and involved chemicals.
