• 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

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.

& SMWA

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
