Laggan : borehole drilling and testing

A borehole for potential public water supply was drilled at Laggan Bridge in August 2004. The borehole was commissioned by Scottish Water. The project was managed by Mott MacDonald. Advice on borehole siting, construction and testing was provided by the British Geological Survey (BGS). The borehole was drilled by Raeburn Drilling and Geotechnical. Hydrofracturing and test pumping were carried out by Drilcorp in October 2004. This report presents geological and hydrogeological data collected during borehole drilling and testing and assesses the hydrogeological characteristics of the borehole and the surrounding aquifer with reference to the suitability of the borehole to provide a public water supply.
