Distribution Phase 1
Phase I Water Distribution System Improvements
Water distribution system leaks
Distribution system piping System
consists of 15 miles of water lines 12 miles of Asbestos Cement pipe 3 miles a mix of PVC and other pipe Oldest located (so far) is from 1926 Most was installed in the 1950s and 1960s
6
Distribution system pump stations
pump stations, necessary due to terrain Portions of system less than 20 psi No capacity to allow additional connections to some of the pump stations No fire flow in higher elevation areas Age of pump stations causing maintenance problems (parts availability, reliability etc.)
Types of System Failures
Phase 2 Reservoir Expansion
Water Supply Status
2010 Situation Critical Shortage of Raw Water Supply Alternatives to Expand Source
N. Fork Reservoir Expansion New (additional) North Fork Reservoir Garrison Lake Do Nothing
Water Loss (Yr 2009 52% - Yr 2010 @ 57%) Less Than Average Year – Requires Conservation

Water Supply Status
2010 Situation Critical Shortage of Raw Water Supply Distribution System is Failing Continue Leak Detection and Repair Water Loss (Yr 2010 @ 57%) PER/EA – Evaluation of Expanding Source
Replacing Distribution System Expansion of N. Fork Reservoir
Funding Applications
Water Consumption Practices
Recommendations
Reduce Water Losses to Less than 10%
Replace Distribution System
Implement Conservation During Drought (15% Reduction in Water Usage) Expand Existing Impoundment 59 acre-feet (19.4 Million Gallons) 38 foot Dam Height
Release Minimum Stream Flow - 0.14 cfs

Payment and interest calculations $4,000,000 loan amount, 3.5% interest, 40 years $6,000,000 loan amount, 1% interest, 30 years Rate based payback Payment is 419,797.81 per year, or approximately $52.45 per customer per month. Total water (only) bill for this scenario is $94.45 Property Tax based payback General Obligation, 100,000,000 assessed value $4.1980 per thousand of assessed value
Payment based on $6M General Obligation bond and $4M Revenue Bond General Obligation bond $2.3249 per thousand of assessed value. Revenue Bond requires rate increase of $23.40 per month per customer.
COUNCIL DECISION REQUIRED: If the vote for either the general obligation bond fails, or the revenue bond fails, the project cannot be completed. Both MUST pass in order for the funding package to be viable.
