Peak water

CO river basin - Supply / demand have crossed

Vulnerable water (NREL slide)

single pipe delivery systems - 50% landscaping!

Peak demand ~3.5x avg.

Aussies - matching the source to the service

"lost water" (recharge question re 35M gallons/day in NY)

energy intensity of water per acre foot -- Denver 350K AF/yr; imagine at $100/AF/yr... (Energy Matters slide)

  • CA - 19% of energy allocated to moving water

100K AF gap:

  • bring water from Green River?
  • bring from CO river, Yampa river
  • imagine water rates escalating due to pumping & attendant Carbon footprint

Portland - 1/3 days - untreated runoff into Puget Sound b/c system cannot handle volume

Building water budgets with real price signals

impact on price signals in CA in the context of irrigation

Focus on service, not gallons.

in CO, ag = 85% of water use, 2% of GDP, notwithstanding some counties where there are disproportionate impactsÂ
