Much of Scotland's water infrastructure has been let to Scottish Water Solutions to maintain, upgrade and operate under a 30 year PFI deal.
Scottish Water Solutions consists of Scottish Water (51%) and two consortia (49%).
These are UUGM led by United Utilities with Galliford Try and Morgan Est; and Stirling Water led by Thames Water with Gleeson (now Black&Veatch), and Alfred McAlpine. Stirling Water runs Edinburgh's water treatment, under the guise of Stirling Water Seafield. Thames Water is contracted to run the Seaeld sewage treatment works on behalf of Stirling Water Seaeld and is eight years into a 30 year contract.
It is obliged to operate Seafield to the standards set by the Scottish Environmental Protection Agency.
