Energy Intensity in Water


… a digression …


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!!


In fact, this much …

Conservative estimate of

total amount of pee

produced in history

Total amount of fresh

water on Earth


“There’s no such thing as fresh

water, just clean water.”

Charles Fishman, The Big Thirst


Wastewater Treatment Prior to Discharge


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

Case Studies in Water

Management


Las Vegas

Population 2010 : 584K



Water Source : Lake Meade, with federally mandated restrictions

Established 1905


“… 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


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


Atlanta

Population 2010 : 5.7M



Water Source : Lake Lanier via Chattahoochee River

Established 1829

Atlanta water strategy?


“Nowadays people know the price of

everything, and the value of nothing.”

Oscar Wilde, The Picture of Dorian Gray


The Economics and

Politics of Water


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


You think your infrastructure is old …

Minimum need by people

Minimum Needed by River

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

Leak Detection


• 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
