<br />Feasibility Report for Improvement ofPaonia's Water Supply System'
<br />Town of Paonia
<br />April 21, 2000
<br />
<br />EXECUTIVE SUMMARY
<br />
<br />GEl Consultants, Inc, (GEl) in association with WestWater Engineering (WestWater) and BBC
<br />Research and Consulting (BBC) was retained by the Town of Paonia in 1999 to perform a
<br />feasibility report for the improvement ofPaonia's water supply system.
<br />
<br />The Town's water supply system includes 14 spring collection units with a total .water right of
<br />9,9 cfs, approximately 20 miles of raw water supply pipelines, Todd Reservoir,t,Wo small water
<br />treatment plants and three treated water storage tanks,:;-.:':it. ,{; 7

<br />WestWater estimated the firm yield of the Town's water supplisystern:i'\t approximately 203
<br />million gallons (623 acre-feet), This is a 2-yearl;lverage..based on the)989-1990 drought event

<br />A comparison of the average annual fi!ffi' yield and 1999 pianiinflows indicates that the Town
<br />currently has a tap deficit of about 1 Q9iaps and. th~e could be severe water shortages during dry
