II. ADJUSTMENTS TO THE AGENDA: None
III. PRESENTATION: "Water Supply Alternatives Evaluation and Selection"
Carollo Engineers determined that any alternative for water supply would need to supply
849 AF in order to meet projected shortages of water.
Six main supply alternatives:
1. Recycled Water
2. TAP Pipeline
3. Expansion of TID supply
4. Additional Ashland Creek Impoundment
5. Groundwater/Aquifer Storage & Recovery (ASR)
6. Expanded or redundant WTP
IV. DISCUSSION:
Recycled Water: This option has the lowest cost (930 AF) but due to the need to obtain
water rights from citizens, it may be difficult to implement. There were three different
options for recycled water but the potable demand offset was between 0.1 — 0.6 mgd.
TAP pipeline: No changes have been made to the pipeline analysis. The capacity is 688 AF.
Expansion of TID supply: The original Ashland canal piping appears to be hindered
due to water rights law, but new rights would not be available. If it were feasible, the
capacity would be 1,679 AF. A revised project could pipe only the City's portion of the
canal, which would have a capacity of 273.8 AF.
Additional Ashland Creek Impoundment: This project includes updates to the
Winburn versus Ranger Reservoirs. Estimates include material, quantities, costs and
impacts. In addition, the City may not be able to get additional water rights from
Ashland Creek.
Groundwater / ASR (Aquifer Storage & Recovery): Requires wells with gpm of
around 100 each. Regular testing requirements are not defined but may include iron and

manganese. There would have to be a feasibility study, testing and permitting that could
be as high as $1 M. Also, there has been no long term testing to show viability of the
wells. ASR has a low probability of success as there is little information to confirm what
areas are suitable. Numerous challenges also include —
• Rights to high -quality water for recharge
• Access to the land for the project
• Infrastructure to convey the water to the City
Expanded or redundant WTP: Expansion of the existing WTP will be required for all
packages. Since current capacity is about 7.5 mgd any expansion would need to be up to
10 mgd. This could be achieved if there was restoration of two existing filters and
improved disinfection.
Supply Package Evaluation:
Two of the alternatives meet all of the LOS goals on their own.
• Tap Pipeline
• Groundwater
The remaining supply packages do not provide a redundant potable supply:
1. Recycled water system
2. TID Expansion
3. Winburn Dam
4. ASR
The Committee ran out of time to complete discussion and rank the packages according
to the evaluation criteria.
V. NEXT MEETING / SUGGESTED TOPICS:
• Mike Faught will speak on the Walnut Street water overflow/overage
• Voting rights
• Chair position- duties, etc
• Approval of minutes
October 21, 2010 was scheduled to be a public open house but due to time constraint and
amount of information presented to the committee, there wasn't enough time to review all
of the water supply alternative packages for final ranking.
Tentative Upcoming Meetings:
October 21't — Follow up meeting
Nov 18th for public open house - Thursday
December meeting for picking one choice to be presented to Council
VI. MEETING ADJOURNED: 6:18 p.m.
Respectfully submitted by
Brenda Barker, Administrative Assistant
