ABSTRACT
This chapter presents a logical process for the planning and implementation of aquifer storage recovery (ASR) projects, which has been developed as a result of experience at several existing operational recharge sites, and familiarity with others. A minimum of three phases is appropriate namely Preliminary Feasibility Assessment and Conceptual Design, Field Investigations and Test Program, and Recharge Facilities Expansion. Several elements comprise an ASR preliminary feasibility assessment. Location of the ASR wells at the problem areas in the distribution system can meet both the primary and secondary objectives since excess water would be stored during low demand months, maintaining adequate line velocity. Careful evaluation of area hydrogeology can lead to the selection of suitable storage zones, recharge water sources, and treatment requirements, and usually affects the location and design of ASR facilities. It is important to collect adequate data to permit interpretation of ASR results at the end of the program.
