Overview• History of the PDWG• Three Steps to Renewable

Water–Efficient Use–Sustainable Use–Reliable Use

• Conclusions

Palmer Divide Water Group

• Why?: Individual Members are too small to finance and construct a water import project

• In 2003 PDWG began to:– Recruit Additional Members– Explore Alternatives for Organization– Protect Potential Sources– Study New Water Sources

• Expensive: $200million or $10,000/af (with storage)

•Perhaps only one well field left

•Mined water

•Water Rights are all Privately Held

Three Steps to Renewable Water

• Efficient Use

• Sustainable Use

• Reliable Use

• Transit Loss Study under EPCWA

• Interconnection of Potable Systems

• Public Safety–Firefighting

–Emergency Backup

Efficient Use

• Stretch Existing Supplies by:–Mining Other Parts of the

DRAFT

1. The Palmer Divide Water Group needs Colorado Springs Utilities much more than CSU needs PDWG.

2. Even at full build-out, the PDWG rate base is too small to finance a renewable water import project on tap fees and water rates alone.

3. The PDWG must compete for renewable water.

4. Becoming part of a Water Conservation District would make PDWG a stronger competitor.

5. First, we must use our local water efficiently.

6. Storage is important.

7. The time to buy renewable water is now.

8. We may need a private sector partner.
