 About the Board

Irvine Ranch Water District is governed by a five-member publicly elected board of directors. These officials are responsible for district policy and decision-making on a large range of issues. Board members participate in bi-monthly board meetings and committee meetings where they evaluate and provide guidance on important water resource and reliability projects, including water recycling, water use efficiency programs, infrastructure projects and the water banking program. They have approval authority on critical district projects.

Irvine Ranch Water District and its board members believe it is essential to be connected and accessible to the communities they serve. Board members frequently attend community and industry meetings within the service area, which includes Irvine, Lake Forest, Newport Beach, Costa Mesa and Orange, as well as unincorporated areas of Orange County, such as Orange Park Acres and Santiago Canyon. IRWD board members actively participate in meetings at the Orange County Water District, the Municipal Water District of Orange County, the Orange County Sanitation District and the Metropolitan Water District of Southern California. Board members connect with the business community through the Orange County Business Industry Association and the Orange County Business Council. Board members also contribute regularly to water supply reliability discussions and policy efforts at the state and federal level to ensure that IRWD customers continue to enjoy a high level of service at the lowest possible cost – now and into the future.

Public elections are held every two years and directors serve four-year terms. For information on elections, please visit the Orange County Registrar of Voters or read about the election methods. Terms are staggered to ensure continuity.
