In order to meet the growing demand of the City, new groundwater wells will have to be
constructed as necessary. The City intends to continue to use groundwater as the sole source of
potable water supply.

Notes:

The "other" category indicates raw water deliveries and local surface water deliveries that are
managed and negotiated by Santa Clara Valley Water District for the purposes of recharging the Llagas
and Coyote Valley groundwater. It also includes the City of Gilroy recycled water demand, which offsets
pumping from the Llagas Subbasin. These water supplies are indicated on this table for completeness
of the Llagas and Coyote Valley groundwater budgets.
