This comprehensive, how-to manual and guide demonstrates how to produce a long term Integrated Resource Plan for a water utility. It helps water resources planners develop and implement a comprehensive work plan that responds to technical and institutional questions that must be addressed before deciding how to develop new water supplies.

The third edition has been completely re-arranged to better reflect the water resources planning process. Several areas of the manual have expanded information, such as: stakeholder involvement throughout the process, reclaimed water and other source water alternatives in the portfolio of solutions, and evaluating alternatives. Also included is a reference to AWWA standards and manuals of water supply practices for sources of additional information.
