Standard Guidelines for Managed Aquifer Recharge, ASCE/EWRI 69-19, provides a thorough and up-to-date description of Managed Aquifer Recharge (MAR) projects. Ongoing demand for water supplies and the need for water storage have led MAR to becoming an increasingly important component for both storage and supply in regional water planning and management. Over the past several decades, much has been learned regarding how to design and implement a successful, cost-efficient MAR project and what pitfalls exist that prevent MAR success. With this standard, many water resources professionals can become aware of the benefits, techniques, standard practices, and applications of MAR.

The standard includes details on planning, design, construction, operation, monitoring, and closure of MAR projects, along with background information on groundwater and MAR concepts. It also describes the economic, environmental, and legal considerations, such as water rights, laws, and regulations, as well as field investigation and testing procedures that may apply.

The content of this standard has been designed to meet the needs of water resources planners and stakeholders during the initial evaluation and planning phases, along with the needs of engineers, hydrologists, and other professionals for standardization of MAR practices from conceptualization to operation.
