… a digression …
NASEO 2015 Annual Meeting
A brief history of pee …
Humans pee ½ a gallon/day
Elephants pee 40 gallons/day
Large dinosaurs peed 40 gallons a shot!
Humans have been here for 2 million years
Elephants for 10 million
Large dinosaurs for 500 million
Conclusion? That’s a lot of pee!!
NASEO 2015 Annual Meeting
In fact, this much …
Conservative estimate of
total amount of pee
produced in history
Total amount of fresh
water on Earth
NASEO 2015 Annual Meeting
“There’s no such thing as fresh
water, just clean water.”
Charles Fishman, The Big Thirst

Wastewater Treatment Prior to Discharge
NASEO 2015 Annual Meeting
Reuse and reclamation
Every gallon reused is a gallon not sent to waste treatment
Technologies exist to reclaim and reuse on site
Saving water saves energy … but knowing what water to save is not easy

“… people don’t want to come to the desert,
they want to come to an oasis in the desert –
what’s an oasis without water?”
Steve Wynn, Casino Operator
NASEO 2015 Annual Meeting
Las Vegas Water Strategy
Two key areas
Sophisticated system wide reclamation
Aggressive regulation/incentives to reduce usage
Leading to
Full recycle back to Lake Mead
Residents paid $45,000/acre to remove grass
Low flow fixtures and plumbing
Artificial lakes banned
Drip irrigation
… and a host of other initiatives

Pricing Overview
True costs of our water are not recovered
• Current pricing covers the variable costs
Infrastructure is not being replaced
• Life expectancy municipal water treatment
infrastructure – 50 years
• Average age of US infrastructure – 75 years
One gallon in six leaks from pipes in the US

Pricing model proposed to deal with excess demand for water from the Murray-Darling river system in Australia
Goal• Ensure the long term health of the river
• Provide access to a minimum level of water for all people living on the river
• Ensures true economic value is recovered from ALL users

• Water and energy use inextricably linked
• Population growth, along with agricultural and industrial demand, driving water scarcity
• We do not currently pay the true cost of water … but those days are ending
• Better pricing models drive better water usage
• Making better decisions requires better data
