Annual Water Use Table - Irrigation Plan#
Instructions
- Irrigated areas for each zone should be a "best estimate," splitting areas between zones as necessary. For drip irrigation, the irrigated area should estimate the area actually wetted by the emitters.
- Determine the average annual water use (in gallons per square foot) by referring to the hydrozones listed on the Water Use Table on the landscape plan.
- Determine the annual total water use (in gallons) by multiplying the irrigated area (in square feet) by the average gallons per square foot for that zone.
- Divide the total water use by the irrigated area to determine overall gallons per square foot (not to exceed 15 gal./s.f.).
