WILLMAR -- Willmar City Council's Public Works/Safety Committee will request council authorization next month to advertise for bids from companies to construct the western interceptor sewer line.
The 2.46-mile western interceptor is proposed to be constructed along the city's western border and will serve the new industrial park and west and northwest Willmar where the current sanitary sewer system is at capacity, according to city officials.
Joshua Halvorson, program manager in the Willmar office of Donohue and Associates, the city's project consultant, said plans and specifications have been completed.
He told the committee this week that the project has been reviewed for conformance with regulations and is authorized by the Minnesota Pollution Control Agency and the Minnesota Public Facilities Authority, which finances municipal infrastructure projects. The committee voted to request council authorization May 7 to advertise and open bids June 5 and award a contract June 18. Completion would be Nov. 1, 2013.
But before the project can proceed, the city needs the Federal Aviation Administration to release the old airport property to the city. A portion of the western interceptor sewer will cross the old airport property where the city wants to develop an industrial park and the city can't construct the sewer line or anything else there until FAA releases the land, according to officials.
City Public Works Director Holly Wilson said bid specifications have a 90-day waiting period to try to ensure the city would have the land release before awarding the contract.
The city has submitted documentation to FAA for the first phase of the land release and is preparing documentation for the second phase of the land release. The second phase is where the sewer line would be built.
Wilson hopes the land releases will be approved by the end of June. The last date that the contract could be awarded this year is the end of August, she said.
The western interceptor will connect at 30th Street and 30th Avenue Southwest just south of I & M Landscaping Nursery with the southern interceptor, which carries all municipal waste to the new treatment plant west of the city.
The western interceptor will proceed north along 30th Streetto 19th Avenue Southwest, cross 19th Avenue, proceed north along the west side of County Road 5 to the old airport, then proceed west along the route of the proposed Trott Avenue extension to the power line easement, then proceed north to U.S. Highway 12 just west of Plumbing and Heating of Willmar, cross Highway 12 and connect with the existing sewer system in the Voss Park neighborhood.
