MAWA EPPT and ETWU Calculations

Project Name: Duong -Doa Residence

Project Location: 1070 Cinnabar Hills Road, San Jose CA

Total Landscape Area: 7,390.0 sq. ft.

Date: 4/20/17

MAWA CALCULATIONMAWA = (Eto)(.62)[(.0.55xLA) + (1-ETAF x SLA)]

MAWA = Maximum Applied Water Allowance ( gallons per year)

Eto = Reference Evapotranspiration (inches per year)

.62 = Conversion Factor (to gallons)0.55 = Et Adjustment Factor (ETAF)

LA = Landscape Area including SLA (square feet)0.45 = Additional Water Allowance for SLA

SLA = Special Landscape Area (square feet)

Eto = 45.3Conversion 0.62ETAF 0.55LA = 7,390SLA = 0

MAWA = 114,155.5 gallons per year 15,261.4 cubic feet per year

MAWA with EPPTMAWA = (Eto-Eppt)(.62)[(.0.55xLA) + (1-ETAF x SLA)]

Eppt= 25% of Annual precipitationEto = 45.3Eppt= 3.75ETAF= 0.55LA = 7,390SLA = 0

MAWA w/ EPPT = 104,731.3 gallons per year 14,001.5 cubic feet

ETWU CALCULATIONETWU = (Eto)(.62)[(PF/IE)(LA)

ETWU = Estimated Total Water Use Per Year (gallons) ETo = Reference Evapotranspiration

PF = Plant Factor from WUCOLS (Region 2, Water Use: H 0.7 - 0.9, M 0.4 - 0.6, L 0.1 - 0.3, VL < 0.1, All Turf 0.8)LA = Landscape Area ( High, Medium, and low water use areas)( square feet)SLA = Special Landscape Area.62 = Conversion FactorIE = Irrigation Efficiency (drip spray and bubblers .81, sub surface .81, spray sprinklers .75ET Adjustment Factor (ETAF) .55 for Residential and .45 for Non Residential
