Senior Management

IRWD was established in 1961 as a California Water District under the provisions of the state of California Water Code. As a special district, IRWD is able to focus on its four primary services - providing high-quality drinking water, sewage collection and treatment, production and delivery of tertiary-treated recycled water, and urban runoff treatment. As an independent, not-for-profit public agency, IRWD is governed by a five-member publicly elected Board of Directors. Board members are elected by division for four-year terms. The Board is responsible for the District's policies and decision-making. Day-to-day operations are supervised by the General Manager and implemented by staff.
