Association of California Water Agencies
The Association of California Water Agencies (ACWA) is the largest statewide coalition of public water agencies in the country. Its nearly 450 public agency members collectively are responsible for 90% of the water delivered to cities, farms and businesses in California.

ACWA was formed in 1910 by five irrigation districts. Originally known as the Irrigation Districts Association (IDA), members voted in 1973 to rename the group the Association of California Water Agencies to better reflect its changing role in California.

ACWA’s mission is to assist its members in promoting the development, management and reasonable beneficial use of good quality water at the lowest practical cost in an environmentally balanced manner.

In fulfilling its role, ACWA identifies issues of concern to the water industry and the public it serves; accumulates and communicates the best available scientific and technical information to the public and policy makers; facilitates consensus building; develops reasonable goals and objectives for water resources management; advocates sound legislation; promotes local service agencies as the most efficient means of providing water service; provides additional services of value to its members; and fosters cooperation among all interest groups concerned with stewardship of the state’s water resources.
