A new construction project’s design case for sewage conveyance requires 1,650 gallons of
water a day for an office building of 900 FTEs. The team has installed high efficiency
toilets that use 1 gallon per flush and high efficiency urinals that use 0.5 gallons per flush.
The office building is open 260 days per year. What amount of water per year will have to
be treated to tertiary standards to earn exemplary performance for Water Efficiency Credit,
Innovative Wastewater Technologies?
A: 429,000 gallons
B: 1,650 gallons
C: 214,500 gallons
D: 2,145 gallons

参考答案: A

本题解释:
Notes:
To earn exemplary performance, the project must reduce potable water use for sewage
conveyance by 100% OR by treating on-site and either re-using or infiltrating 100% of the
wastewater.
This project uses 1,650 gallons/day for 260 days per year. This means 429,000 gallons will have
to be treated for reuse or infiltration to earn the extra point.
