Mary Ann Dickinson President and CEO, Alliance for Water Efficiency Mary Ann Dickinson is the Former Executive Director of CalWEP and is President and CEO of the Alliance for Water Efficiency. She has over 40 years of experience, having worked at the Metropolitan Water District of Southern California, the South Central Connecticut Regional Water Authority, and the Connecticut Department of Environmental Protection. Mary Ann was also the first Executive Director of the California Urban Water Conservation Council.


Twenty-five years ago, in response to a goal set by the State Water Resources Control Board to save more than one million gallons of water through conservation efforts, hundreds of water agencies, environmental groups, and other interested parties signed a historic Memorandum of Understanding (MOU). A first of its kind collaboration among a vast array of stakeholders, the council established voluntarily best management practices for California water agencies to conserve our most precious resource while documenting their successes.

With increased pressure from a changing climate – more severe droughts and water uncertainty – and new mandatory regulations from the state of California, including new framework to “Make Water Conservation a California Way of Life,” the Council membership voted to allow the organization to sunset, replacing it with a new one: the California Water Efficiency Partnership, or CalWEP.

In March of 2018, the California Water Efficiency Partnership launched as an innovative leader, voice and expert on water efficiency in California. The Partnership carries forward the expertise and collaboration that was a Council hallmark but with a new name and new, nimble framework. CalWEP is committed to providing cutting-edge expertise on California water issues, challenges, and opportunities within a broad collaborative framework.


Members of CalWEP are voluntarily organized into two main committees. These committees help drive our work and prioritize our agenda. Members are invited to join one or more committee. As needed, “task forces” will be formed to address more specific, time-limited topics. Contact Michael Walker to sign up at Michael(at)calwep(dot)org.
