Franklin CID, CLIA, don.franklin@hunterindustries.com](https://reader036.fdocuments.net/reader036/viewer/2022062603/5f1fd24bd5abf93ecc56ab4f/html5/thumbnails/2.jpg)
What Are The Goals Of Irrigation
Design?
Provide adequate soil moisture content in the plants root zone, as a supplement to rainfall.
Protect the landscape investment.
Minimize financial risk of a costly under or over designed system.
Minimize the amount of water the system will need to use.
Minimize the amount of labor required to efficiently operate the system.
Provide a system that will last for years with as little maintenance as possible.

Franklin CID, CLIA, don.franklin@hunterindustries.com](https://reader036.fdocuments.net/reader036/viewer/2022062603/5f1fd24bd5abf93ecc56ab4f/html5/thumbnails/3.jpg)
Establishing the Water Reqirement
MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)]
MAWA = Maximum Applied Water Allowance (gallons per year)
ETo = Reference Evapotranspiration (inches per year)
0.62 = Conversion Factor (to gallons)
0.7 = ET Adjustment Factor (ETAF)
LA = Landscape Area including SLA (square feet)
0.3 = Additional Water Allowance for SLA
SLA = Special Landscape Area (square feet)
MAWA = (51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 0)]
= 1,108,870 gallons per year
To convert from gallons per year to billing units (CCF) per year:
1,108,870 ÷ 748 = 1,482 CCF per year (100 cubic feet = 748 gallons)
![Page 4: IRRIGATION DESIGN & MAINTENANCE FOR …cesacramento.ucdavis.edu/files/137691.pdfIRRIGATION DESIGN & MAINTENANCE FOR MAXIMUM EFFCIENCY Donald D. Franklin CID, CLIA, don.franklin@hunterindustries.com](https://reader036.fdocuments.net/reader036/viewer/2022062603/5f1fd24bd5abf93ecc56ab4f/html5/thumbnails/4.jpg)
ETWU = (ETo x 0.62) x [((PF x HA)/IE) +SLA]
Where:
ETWU = Estimated Total Water Use per year (gallons)
ETo = Reference Evapotranspiration (inches per year)
PF = Plant Factor from WUCOLS (see Section 491)
HA = Hydrozone Area [high, medium, and low water use areas]
(square feet)
SLA = Special Landscape Area (square feet)
0.62 = Conversion Factor
IE = Irrigation Efficiency (minimum 0.71)
1,090,740 = (51.6*0.62)*((0.65*50000)+0)
COMPLYING WITH LOCAL ORDINANCES

CALCULATING REQUIRED SYSTEM GPM
GPM = (0.0104 x ETo x Area x Kc) / (DU x Hrs. Available)
Variable Value Ranges:
GPM = gallons per minute required
ETo = peak daily evapotranspiration for the worst case scenario in inches
Area = area to be irrigated in square feet
Kc = Crop Coefficient – use 1.0 if actual crop coefficient is not known
DU = distribution uniformity or irrigation efficiency
Hrs. Available = hours available for irrigation each day in the worst case
0.0104 = constant for conversion of area, flow and inches per day, etc. into
common units
(0.0104 x 0.36 x 50,000 x 0.7) / (0.71 x 8) = 23.07 GPM

Selecting Sprinklers & Spacing Ranges
• PSI: – sprinkler operating pressure.
• Radius: – distance from the sprinkler to the edge of throw
(in feet).
• GPM: – flow rate of the sprinkler with different size
nozzle orifices.
• Precipitation Rate: – delivery rate based on nozzle,
arc and spacing.
Sprinkler performance charts contain the following:
