Sustainable Groundwater Management

Haga clic aquí para español

For many decades, the San Benito County Water District (SBCWD) has been a steadfast steward of groundwater resources in San Benito County, actively managing the groundwater basins to protect water quality and maintain a reliable and sustainable water supply. For SBCWD and other water agencies, it’s getting more and more difficult to ensure long-term groundwater sustainability, with climate variability, growth in both urban and agricultural land use, changes in types of agricultural uses, availability and cost of imported water, and other factors.

To assist water agencies like SBCWD in meeting these significant groundwater challenges, the state-wide Sustainable Groundwater Management Act was passed in 2014. This law outlines new requirements and tools for ensuring the long-term sustainability of these critical sources of water supply.

A State decision on the proposed basin consolidation is expected this fall.
