Welcome to Westside District Water Authority Groundwater Sustainability Agency

Westside District Water Authority was formed in 2012, and it comprises three water districts: Belridge Water Storage District, Lost Hills Water District, and Berrenda Mesa Water District. Those three districts and the Westside District Water Authority serve to ensure a reliable supply of water from the State Water Project to its users. In 2022, Westside District Water Authority became an independent Groundwater Sustainability Agency to implement the Sustainable Groundwater Management Act on behalf of the three districts.
