Recommended Improvements
-Water Storage Tank Repair
--Re-coating
--Foundation repair
--Extend tank ladder and overflow piping
--Remove altitude valve and repair valve vault
--Erect tank site fencing
--Improve access road
-Repairs will only last 15-20 years!
18
Recommended Improvements
-Water Storage Tank Replacement
--Install new glass-fused-to-steel storage tank (concrete
considered)
--COnnect inlet/outlet piping
--Erect tank site fencing
--Improve access road
-Replacement Tank will last for 40+ years (with routine
maintenance)
19
Recommended Improvements
-Distribution System
--Replace old cast iron pipe with 8-inch cement-lined
ductile iron pipe (D.I.P.) hydrants and valves
--Replace services from main to front of private property
-Tank Transmission Main
--Assess condition during design and replace with D.I.P. if
necessary

Project Cost Alternatives
-Project Alternative No. 1 - $2,464,000
--Water Supply and Treatment Repairs
--Water Storage Tank Repair
--Distribution System Improvements
-Project Alternative No. 2 - $2,706,000
--Water Supply and Treatment Repairs
--Water Storage Tank Replacement
--Distribution System Improvements
-Project Alternative No. 3 - $3,025,000
--Alternative No. 2 + New Transmission Main
22
Funding Programs
-Grants, low/no interest loans
--Drinking Water State Revolving Fund (DWSRF)
--USDA Rural Development (RD)
--GOvernor's Small Cities Grants (Community Development)
-State Legislature Member Item (help with planning and
administrative costs)

23
USDA Rural Development Loan
-Low interest loan financing - 38 years at 4.5% interest
-Can not count on financing tank repairs - will not last term
of loan
-Assume tank repairs under Alternative 1 to be financed
through bonding, 20 yrs @ 6%
-Estimated Debt service cost for typical household:
--Project Alternative No. 1 - $368/year
--Project Alternative No. 2 - $387/year
--Project Alternative No. 3 - $433/year
24
Current Water User Costs
-Current Water Rates - 90% Operation and Maintenance
(O&M) + 10% Payment on debt from 2001 W. Main St. Project (paid in 2009)
-Annual cost for household using 200gal/day = $250 +/-
-Debt will go away in 2009, but inflation will increase O&M
cost, so assume current rate is O&M cost for 2010

25
Total Post-Construction Annual Costs (Estimated for
Typical Household)
-Project Alternative No. 1 - $620/year
-Project Alternative No. 2 - $639/year
-Project Alternative No. 3 - $685/year
26
Total Post-Construction Annual Costs (Estimated for
Typical Household)
-Project Alternative No. 1 - $620/year [DARKED OUT]
-Project Alternative No. 2 - $639/year
-Project Alternative No. 3 - $685/year
-But wait... tank repairs will only last 20 years!
-Assuming tank replacement needed after 20 years:
$620/year => $700/year
27
Total Post-Construction Annual Costs
-Grant Funding can reduce costs
-Example: $500,000 grant
--Project Alternative No. 1 - $549/year [DARKED OUT]
--Project Alternative No. 2 - $568/year
--Project Alternative No. 3 - $613/year

Summary
-Issues throughout water system
-Address all issues in single project
-Replace 70+ year old mains
-Replaceing tank more cost-effective than repair
-Replace asbestos-cement tank transmission main?
-Low-interest RD loan financing available
-Grants can lower overall user cost impact
