DEEPER THAN CONSERVATION: WATER REUSE. WHAT’S POSSIBLE?
DEEPER THAN CONSERVATION: WATER REUSE. WHAT’S POSSIBLE? • Water Closets • Urinals • Trap primers (floor drains, floor sinks) • Irrigation…and other uses approved

by the Authority Having Jurisdiction
DEEPER THAN CONSERVATION: WATER REUSE. WHAT’S POSSIBLE?
ANALYZE
• We have more gray water supply than we can use in non-potable uses. • What else can be done?
DEEPER THAN CONSERVATION: WATER REUSE. WHAT’S POSSIBLE? • Clothes washing demand is 181,069 gallons/year, which is still less

than the available amount of water.
THE COST OF GRAY WATER: DOES IT PAY? • Chapter 16 allows the Authority Having Jurisdiction to determine permissible uses. • Couldn’t clothes washing be an approved use? • What’s the risk of using treated gray water (colorless, odorless) for washing clothes?
Will need to be potable water

Going to the sewer!

SUPPLY AND DEMAND: WE CAN DO IT ALL WITH GRAY WATER, BUT…

THE COST OF GRAYWATER, AND THE POSSIBLE PAYBACK: WHY INVEST?
PLANCHECK AND REGULATORY APPROVALS, LESSONS LEARNED…. • Talk to your building officials early. • Case management meetings as you

design is ideal (try to make the plan checker part of the design team - fewer surprises is better for all). NSF 350 approval of system a pathway for approvals - but there approved systems are limited.
