downtown water line
replacement project    Phase 3 & 4
Recommendations
replace waterline
[
repair joints impractical
use ductile iron, rubber gasket joints
evaluate alternative routes
estimated $6.3 million
The conclusions of the April study recommended complete pipe replacement using state-of-the-art ductile iron pipes and rubber gasket joints.  Cast iron has been obsolete for over 40 years in the water industry and because the problematic joint sealant was used at every joint (approximately one joint every 18’, over 480 joints total in the water main) it is impractical to try to dig out and replace each joint.

As a result, the study recommended full pipe replacement at an estimated total cost of $6.3 million over 6 years in a 4 phase construction project.  In addition the study recommended relocating the water main out of the core business district to minimize construction impacts on traffic, business and residences.

This report provided an explanation of the new route selected for the water main replacement and corresponding construction schedules.
