RE: Savings Achieved by the Water Shortage Area Sprinkling Ban
The following savings from the subject ban are estimated by the staff to be
those achieved during the two month period of the ban.
Of the estimated 8,965 acres of citrus in the subject area, about 2,331
acres or 26% is irrigated. Normal irrigation is about 10 to 12 inches
per year, usually applied over a four month period. The current period
was not one in which high levels of irrigation are used. It has been
estimated that about 10% of the systems in the area do operate periodi-
cally during this period. A savings of 0.03 mgd or a total of 1.8 mil-
lion gallons has been achieved.
Three major golf courses are operated within the subject area, however,
due to the normal pattern of irrigation during evening hours, it has been
estimated that the 485 acre area has achieved only an estimated 0.004 mgd
or 0.24 million gallon saving.
Lawn and Ornamental Irrigation:
Although this saving is very difficult to estimate, it has been estimated
that approximately 0.01 mgd or 0.6 million gallons have been saved.
Total estimated savings--2.64 million gallons.
