The Water Supply and Water Conservation Management Plan includes a framework for water supply facilities and strategies for resource management. The plan provides for the continued use of existing reservoirs, the completion of three new reservoirs that are in the planning process, three additional reservoirs needed in the future, and the construction of two new storage facilities to drought proof and extend existing supply sources. The plan also calls for the expansion of 28 existing water treatment plants and the construction of six new water treatment plants. Management strategies call for intensive demand management and an aggressive water conservation program. Returning highly treated wastewater to source water is included as part of the District’s comprehensive approach to water resources management. The plan also outlines an education plan to raise public awareness of water supply and water conservation issues.
On May 7, 2009 the Metro Water District Board adopted the updated Water Supply and Water Conservation Management Plan. The updated plans replace the Metro Water District's September 2003 plans as amended.
