• Goal: Shift away from nonrenewable sources of water
• Plan based on three pillars1. Partnerships – Leverage relationships with each other, local
governments in the region, and other water providers
2. Investment – In supply and storage projects, individually and
collectively
3. Efficiency – Become a leader in conservation and the efficient
use of water

Shift to Renewable Supply• Early 2000’s: 60% nonrenewable; Many of the region’s
largest water providers were 100% nonrenewable
• By 2020: 22% nonrenewable
• By buildout (2065) it will be down to 15%
• Some entities are already almost
completely renewable on average

Tremendous Progress

Conservation and Efficiency
• Reduced per capita water demands across the region by 30%
• The region currently averages about 120 GPCD.
• The region is set up to reuse all of the supplies that are legally able to be reused.

• Aurora Water– Offset PWP costs (annual revenue of $10M)
– Continued use of PWP for drought supply
• SMWSA– Renewable supply for SMWSA (100KAF/10yr)
– Allows use of Denver Basin aquifer for drought supply
• Denver Water– Drought and emergency supplies for Denver
Opens the door to regional cooperationTotal Affected Population = 2 million 10
