Sustainable Groundwater Management Act (SGMA)
Recognizing the importance of groundwater, and the consequences of overuse, a package of bills addressing the sustainable management of groundwater in California was approved in 2014. Collectively, these bills are the Sustainable Groundwater Management Act (SGMA).
Our Local Groundwater Basin is known as the East Contra Costa Subbasin
It stretches from Antioch and Bethel Island, through Oakley, Brentwood, Knightsen, down through Discovery Bay, to Clifton Court Forebay. Groundwater from the Subbasin is a vital component of our water supply, along with water from the San Joaquin and Sacramento Rivers that reaches us through the Delta. SGMA took effect on January 1, 2015, and requires all groundwater basins, designated as medium or high priority by the Department of Water Resources, to be sustainably managed by the year 2042. The Department of Water Resources designated the East Contra Costa Subbasin as medium priority based on several factors, including population, number of wells, irrigated area, and groundwater conditions.
Collaborative Groundwater Management Planning in the East Contra Costa Subbasin
To ensure long-term sustainability of the groundwater basin, the District has formed a Groundwater Sustainability Agency (GSA). The District’s GSA is collaborating with GSAs formed by other water suppliers within the Subbasin to create a joint Groundwater Sustainability Plan (GSP). The GSP will be in compliance with SGMA.
