Water Resources Review Committee
Who We Are

• 13 Members
• Serve 300,000 people
• Projected to serve 550,000 people by 2050– 80% of Douglas

County
• 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

Master Plan Update
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.

Uses $800 million in existing infrastructure• Cost Recovery for Aurora’s
Investments• Purchase of existing “Western
Pipeline”
Construction of ~$120M of new infrastructure
What is WISE?
• 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

Future WISE Infrastructure
1. Additional increment of
supply: ~30KAF of additional renewable supplies by 2065
2. Storage (surface and ASR) to
firm existing and new supplies
3. TDS management for new supplies and WISE supplies: Blend water or RO
4. Conservation: Individual member’s efforts and regional
