A contract awarded by the Coon Rapids City Council for the city’s 2012 sanitary sewer lining project came in 14 percent under the engineer’s estimate.
From five bids submitted, the council approved the low bid from Insituform Technologies Inc. USA in the amount of $856,077.60.
The estimate for the project provided by the city’s consultant, SEH Inc., was $975,648.20.
Three of the five bids were under the estimate; the two highest bids both topped $1.2 million.
According to Steve Gatlin, city public services director, Insituform has done sanitary sewer and watermain lining for the city in the past and has done a good job.
This year’s sewer relining program will be in four areas of the city, two large segments and two small areas, including Ninth Avenue, the border street with the city of Anoka, which is reconstructing the street this summer.
Three of the areas are located in the western portion of the city and one in the south.
Sewer relining has been an ongoing project of the city for several years.
“Sections of our sanitary sewer system, generally in the older neighborhoods, have shown significant maintenance difficulties due to root intrusion and open joints,” Gatlin said.
Pipe material is generally clay pipe and was installed in the 1960s and 1970s, according to Gatlin.
The project will only include work on the main line sanitary sewer, Gatlin said.
“All segments to be relined have been televised,” he said.
“Where we have noticed apparent service problems with roots, the homeowners have been notified.
“It has been suggested that the homeowners have their service line cleaned prior to the beginning of the relining project.”
A decision was made by the council when the sewer relining program began, that the city would not be involved in work on private sanitary sewer lines, only the main line in the street, according to Gatlin.
“If homeowners have the desire to have their service reconstructed or relined, we will provide a list of reputable contractors who do this type of work,” Gatlin said.
Work will begin in the summer and be completed by the fall, he said.
The sanitary sewer utility fund has $1.25 million in its 2012 budget for this project, Gatlin said.
The fund derives its revenues from the quarterly utility bills paid by property owners.
