JUSTIFICATION: (Attach additional pages if needed)
The City is in need of a water main liner to be pulled inside an existing water main with several
bends. The City has identified only one supplier that can provide a PVC and Kevlar liner that
can be pulled inside the existing water mains with several bends and still maintain full water
system pressure of 60-150 PSI without excavating across Eagle Road. For this reason, Primus
Liner has been integrated into the plans and specifications of the Eagle Road Water Crossing
project.
The liner is manufactured by Radlinger Primus Line in Germany. Primus Liner may only be
purchased through their lone authorized US reseller xxx. The City is issuing this sole source per
Idaho Code 67-2808 (a)(v) and (viii) below.

Additional benefits while using Primus Liner:
The 12-inch water mains running east to west across Eagle Road (State Hiway 55) at 3 separate
locations, and interstate 84. Each location does not have existing casings around the water
main. To prevent massive damage to the state highway and possible blockage and public
access along one mile for a matter of days, or a week, the mains need casings or liners
installed. If a water main breaks again, additional public property may be damaged since the
last water main incident.
The Primus Liner can be pulled inside an existing PVC water main from an excavated pit (where
a section of the main has been removed) on one side of the road, under the active road into a
receiving pit on the other side. The liner is then inflated, pressure tested and then mechanically
fastened to each end of the water main. When using Primus Liner, the flow rate of the water in
the main will not be reduced to below optimal operating pressure.
Once the liner is installed, If a leak in the liner occurs, the ends can be excavated, liner pulled
out and replaced without affecting the driving public or damaging adjacent property.
