Water
Master Plan
As
indicated in previous chapters, the two largest water providers within
the Urban Services Line are
the District and Cal-Cities. In
addition to the above reference purveyors, the groundwater underlying
the community is pumped by the S&T Mutual Water Company for use by
its customers, by the County of San Luis Obispo for irrigation of the
Community Park, large lot residences for private use, and by
agricultural interests.
The
detailed groundwater analysis conducted indicates the safe urban
purveyor yield of the basin, with the District’s wastewater project,
to be 2,900 Acre Feet per Year (AFY). Given that
the demand to the Basin is estimated at approximately 2,960 AFY, an
additional source of supply, such as recycled water, will be necessary.
Chapter 6 discusses the use of recycled water to address the
entire 60 AFY shortfall. The
recycled water study projects 115 AFY of savings in potable water
pumping by irrigating area schools, the Community Park and the Sea Pines
Golf Course with recycled water from the future wastewater treatment
plant. As a result, this
water conservation measure should adequately provide the additional
source of supply needed to avoid importing water.
Table ES-3 summarizes the projected supply and demand for the Los
Osos Groundwater basin.
