attached in Appendix C) was to lower the pumping units in Wells A-I and A-2 along

with replacing the pumping unit in Well A-3. The pumping unit in A-3 was out of

service and had to be replaced in any regard. Additionally, the age and wear of the

other two pumping units indicated that they would need replacement in 1995 or 1996

also, which suggested that this short term solution was not viable. The solution

chosen (Alternative 3 below) was to replace the pumping units with larger units at

deeper settings to allow the production of 1500 gpm from the three wells combined.

Alternatives Considered:
Alternative Cost Estimate Flow
(gpm)
1 Repair pump unit in Well A-3 $166,638 500 Completed
Continue to use A-I and A-2 $150,000? 600 minimum
(Will need repair in 1995 or 1996) replacement
Add 2 Denver aquifer wells $700,000 500
Total $1,016,638 1600
2 Repair pump unit in Well A-3 $166,638 500 Completed
Continue to use A-I and A-2 $150,000? 600 minimum
(Will need repair in 1995 or 1996) replacement
Drill additional Arapahoe Well $750,000 500
Total $1,066,638 1600
3 Repair pump unit in Well A-3 $166,638 500 Completed
Replace pumping units in A-I, A-2 $394,485 1000
Total $561,123 1500

Preliminary Deshm and Layout

The project has been designed in two separate Phases, relating to the proposed
