7.4 REGIONAL SUPPLY RELIABILITY
Law
As discussed previously, the City uses groundwater as its sole source of supply. In order to
reduce the burden on groundwater resources during periods of prolonged drought, the City has
water conservation ordinances that can be implemented to prevent and prohibit the wasting of
water, while also encouraging the community to conserve.
The City’s supply reliability is dependent on the rate of available recharge for the groundwater
subbasins beneath the City. SCVWD imports raw water through the State Water Project and
federal Central Valley Project for the purpose of recharging the groundwater subbasins they
10620 (f) An urban water supplier shall describe in the plan water management tools and options
used by that entity that will maximize resources and minimize the need to import water
from other regions.
