ACWA is the largest statewide coalition of public water agencies in the country. Our more than 430 public agency members collectively are responsible for 90% of the water delivered to cities, farms and businesses in California. For more than a century, our mission has been clear: to help members promote the development, management and use of good quality water at the lowest practical cost and in an environmentally responsible manner.

ACWA serves the water industry and the public by promoting local agencies as the most efficient means of providing water service; sharing reliable scientific and technical information; tracking and shaping state and federal water policy; advocating for sound legislation and regulation; and facilitating cooperation and consensus among all interest groups.
