CalMutuals brings together California’s mutual water companies, facilitates the exchange of quality information, offers valuable resources, and represents its members through grassroots activities and statewide lobbying.

CalMutuals reaches key legislators, as well as community and local leaders who have the power to make positive changes.

CalMutuals also works to bring small water systems together through our website, newsletters, meetings, workshops and direct mailings.

CalMutuals provides free and discounted online water treatment, distribution and waste water courses to meet state CEU requirements, risk management compliance & human resources tools, and specialty operations support to our members.

It takes money and time to track regulations and mitigate the impact of proposed laws, which is why your membership dues are critical to our success.

CalMutuals annual dues are based on annual revenues and range from $150 to $1,250.
