COMPARISON OF PPP SCHEMES IN WATER SUPPLY PROJECTS BASED ON QUANTITATIVE RISK ANALYSIS

Abstract

  It is a world-wide tendency for water supply industries to introduce more private participation in the project scheme. In addition, there are wide variations in terms of risk allocation between public and private sectors. However, few attempts have been made to conduct quantitative risk assessment with regard to the risk allocation. The aim of the present study is to build a quantitative risk analysis system to find the best project scheme among candidate ones, full privatization, concession, PFI, outsourcing, etc, with the variation of risk allocation. With the case studies, it is confirmed that the system built in this study is equipped with the functions to provide effective information from the viewpoints of both Value for Money for the public and the viability of the project company.
