Water Main Rehabilitation Projects

MISSOULA, Mont., July 23, 2012 /PRNewswire/ -- Mountain Water Company is preparing to rehabilitate old mains in three locations. This includes approximately 750 feet in Russell Street near the S 14^th Street W and Mount Street intersection, 585 feet in the alley between Cherry and Locust Streets from Monroe to Van Buren, and 105 feet along Main Street under Higgins Avenue. These projects will cost a total of $447,000.  

Mountain Water will be using a trenchless technology called cured in place pipe (CIPP) lining. The process involves digging access pits along the project, pulling a liner through the existing pipe, curing the liner with hot water, and finally disinfecting and testing the newly lined water main.  Upon completion of the pipe lining, customer service lines are planned to be re-instated from inside the main with a robotic device. A temporary water system will be installed during the lining operation to provide service to affected customers. 

"The CIPP technique allows us to rehabilitate the old water main with less disruption, less surface restoration, and less overall cost than conventional open-cut methods would have required," commented Logan McInnis, Mountain Water's Chief Engineer.

The Main Street project is scheduled to start on Tuesday, July 24^th and be completed by Monday, July 30^th (testing will be completed by Thursday August 2^nd). Northbound traffic on Higgins Avenue will be diverted into a single lane during the project. 

The Russell Street project is scheduled to start on Wednesday, July 25^th and be completed by Monday, August 6^th (temporary water will remain in place until testing is completed on Friday, August 10^th)  We have accelerated our schedule to eliminate any traffic disruptions during the Western Montana Fair, which starts August 7^th. Starting July 30^th, southbound traffic on Russell Street will be diverted into a single lane, and left turns will not be permitted from Russell Street northbound onto S 14^th Street W. 

The Cherry and Locust Alley project is scheduled to begin on Wednesday, August 1^st and be completed by Monday, August 13^th (temporary water will remain in place until testing is completed on Wednesday, August 15^th). The alley will be closed for the duration of the project.
