Willmar's new sewer line done three months early

WILLMAR -- Officials say the five-mile-long sewer line that will carry municipal waste to the new wastewater treatment plant located west of Willmar is substantially completed -- three months ahead of schedule.

Sewer line contractor S.R. Weidema of Maple Grove notified the city that the 29,145-foot-long interceptor sewer line is ready for its intended use of carrying municipal waste to the new treatment plant. The sewer line is part of the city's $86.2 million wastewater project.

Representatives of project consultant Donohue and Associates and the city inspected the work and recommended Weidema be granted substantial completion of its contract.

Weidema was awarded the contract on Aug. 18, 2008, with substantial completion to be achieved by Sept. 8, 2010. However, substantial completion was achieved on June 14.

Substantial completion allows the owner, which is the city, to take beneficial occupancy and ownership of the built facilities and it starts the one-year warranty period of materials and workmanship on the job, explained John Bryant, lead resident project representative in Donohue's Willmar office.

Bryant reported Weidema's progress to the City Council's Public Works/Safety Committee on Tuesday afternoon, and the committee voted to recommend the council grant Weidema substantial completion of its contract. The council will receive the recommendation Tuesday.

The committee also granted Weidema substantial completion on the westerly portion of the forcemain sewer line that will carry industrial waste from Jennie-O Turkey Store's two turkey processing plants. Substantial completion was granted to the portion that runs between the new treatment plant and County Road 15.

Substantial completion of the remainder of the forcemain between County Road 15 and the pump station next to Jennie-O's Benson Avenue plant is expected in July, according to Bryant.

The Benson Avenue pump station and a pump station serving Jennie-O's Willmar Avenue plant are slated for substantial completion the second week in July, said Bryant.

The new treatment plant is expected to be substantially completed on Aug. 17. After that date, municipal wastewater will gradually be diverted from the old plant to the new plant. By the third week of September, the entire wastewater flow will be directed to the new plant, according to Bryant.

Plans call for the old plant, located just east of the Kandi Mall, to be decommissioned.
