THE INFLUENCE OF THE PRIVATE FINANCE INITIATIVE PROCESS ON PLANT SELECTION AND DESIGN FOR EUROPE'S LARGEST UV PLANT.
Abstract:In order to meet new European Community Directives on effluent, sludge treatment and disposal in Scotland, East of Scotland Water Authority (ESWA), the statutory water services provider for southeast Scotland has worked in partnership with Stirling Water to deliver the benefits of the Private Finance Initiative (PFI) process. The PFI process is applied to projects where substantial capital investment is needed to improve services and where the PFI solution is likely to deliver better value for money and innovative solutions for the public purse. The Seafield and Almond Valley project is the largest PFI water sector project in the UK, covering wastewater treatment plants serving Edinburgh and nearby towns in the valleys of the rivers Almond and Esk. Valued at £100m (US Dollars 170m) the Seafield and Almond Valley Project has been combined with the £30m (US Dollars 51m) Esk Valley Scheme which will upgrade parts of the trunk sewer network and eight storm water works. Stirling Water won both projects on a competitive bid process. The Stirling Water Consortium comprises operational, construction and design specialists – Thames Water, MJ Gleeson and Montgomery Watson.
The design of UV plants is in the early stages of being developed in the UK and therefore guidance is not well defined on the basis of past performance. Matters were further complicated by the fact that settled sewage would also be passed to the lamps. This paper discusses the various stages and influences during UV plant selection. In particular the paper discusses how the Consortium dealt with risk, how the Pilot Plant Trials changed the initial design parameters and the influence of whole life costs. Many of the experiences faced in the Seafield and Almond Valley Project will be similar to others who select UV disinfection technology and seek to achieve environmental benefits, best value for money, guaranteed performance, long-term price security and asset ownership at the end of the contract.
