How to measure outdoor water use
EPA water sense water budget tool
Graywater
Can be used twice? Untreated laundry water, shower water water not in contact with toilet waste or kitchen sinks i.e. Organic matter - for irrigation and flushing
Minimum outdoor water reduction
30%
Blackwater
From toilets, dishwasher, not for flushing toilets
Water sense
Label for indoor plumbing fixtures required, shower heads and faucets
Fixture cut sheet
Document fixture water reduction
Potable water
Water that meets or exceeds EPA drinking water standards, comes out of faucet
Water efficiency
Efficiency first
Rainwater
Non potable water
Process water
Dishwashing, clothes washing and ice, mechanical services
Minimum indoor water savings needed by LEED
20%, has highest priority in water savings
Water efficient appliances
Energy star
xeriscaping
landscaping that eliminates or greatly reduces need for water
HET
High Efficiency Toilet - 1.28 gpf
required reduction in prereq
20% inside - can just pick all watersense things and 30% outside
Watersense
baseline for outside water use
Female to male bathroom average
3:2 times per day, 3 times per day and wash for 15 seconds
spray valve
.6 gpm?
FTE
full 8 hour occupant = 1
what is not strategy for reducing irrigation related potable water use
building level metering (because deals more with inside water) not irrigation
