Updated pollution at Craigton burn Residents walking dogs last week complained of discolouration of the burn in the area which normally runs clear. Scottish Water revealed to the Herald that there had been a discharge of silt into the water as work progressed on a new water mains project for the area. A spokesperson for Scottish Water said: “Caledonia Water Alliance (CWA), our alliance partners, are working on a £30m Scottish Water project which includes the installation of about eight miles of new water mains and will benefit 54,000 people in parts of the Bearsden, Milngavie, Clydebank and Strathblane areas. “On Friday (April 23) there was a brief discharge of silt-laden water to a tributary of the Craigton Burn near Mains Estate, Milngavie when water was being pumped from an excavation on the project.
