Although guidance is available on the economics of water resources in agriculture there is an unfulfilled need for guidance on the specific issues arising in the use of recycled water. This report is an attempt to fill this gap. Recycling includes both untreated and treated wastewater. While the economic concepts discussed in this report are applicable to untreated (raw) and treated (reclaimed) wastewater and to many types of reuse, the main focus of this report is on the use of reclaimed water from community sewerage systems for irrigated agriculture.

This report addresses the economic and financial issues and the methodology and procedures involved in the analysis of water recycling projects. The issue is dealt with in the wider context of water resources and covers human health, water quality, acceptability, institutional constraints, and other factors, all of which have economic implications and affect the feasibility of reuse schemes. The Chapter 1 provides a contextual background. Chapter 2 introduces the case material, drawn from regions of Spain and Mexico. Chapter 3 contains the methodology proposed for the economic analysis of projects, together with the procedure for determining its financial feasibility. Chapter 4 applies this methodology to the analysis of the case studies. Finally, chapter 5 proposes a broader planning framework into which the economic and financial analyses can fit. Chapter 6 draws some conclusions from the report that are relevant to policy makers and professionals working on this topic.
