THE ENVIRONMENTAL VALUE OF RECLAIMED WATER FOR AGRICULTURE PURPOSES
Conventional water resources are over-exploited in much of southern Europe. Consequently, reclaimed waste water is being seen as an alternative water source. To assess the viability of using reclaimed waste water, a comprehensive economic analysis is needed. Within this economic assessment, all environmental benefits including non-market benefits should be included to ensure an efficient and sustainable allocation of the resource. This is also in line with the approach taken in the EU Water Framework Directive. In this contingent valuation study, we estimate the non-market environ¬mental benefits arising from the use of reclaimed waste water for irrigation in the Segura River Basin in south-eastern Spain. Our results support the hypothesis that the reuse of reclaimed waste water provides benefits to society beyond those reflected by the market. The inclusion of these non-market benefits and their comparison with the implementation costs will provide for better informed water management.
