IrrigationQuestion 20 of 100
Under MWELO, the Maximum Applied Water Allowance (MAWA) is based primarily on which factors?
a.Only the number of sprinkler heads
b.The brand of controller installed
c.Pipe diameter and valve count
d.Reference evapotranspiration, landscape area, and an ET adjustment factor
Explanation
MAWA sets a water budget calculated from the local reference evapotranspiration (ETo), the landscape area, and an ET adjustment factor that reflects allowed plant water use. The designed landscape's estimated water use must stay within this allowance. This is the core water-budget concept of MWELO.
