Scottish Water's Katrine water project at the Milngavie Water Treatment Works near Glasgow was named this year’s winner last week.
The facility came on stream last October to supply clearer, fresher drinking water to 700,000 customers in the Greater Glasgow area. Five other projects received commendations. These were Waverley Station regeneration project in Edinburgh, Melrose town centre improvements in the Borders, the Clydebank Swan, Dundee Gasworks land remediation and Clunie Dam, near Pitlochry.
Past Saltire winners include the Clyde Arc in Glasgow, known locally as the "Squinty Bridge", the Falkirk Wheel, the Scalpay Bridge, and Ibrox Stadium in Glasgow
