Wastewater pond project wrapping up
Things are continuing to move along out at Perham’s wastewater treatment facility, with work on the expansion project still expected to wrap up this month.
In an email to the Focus last week, City Manager Kelcey Klemm said the facility’s new 20-acre holding pond had passed the tests needed to be put to use, allowing workers to pump materials into it from one of the older holding ponds.
This transfer of wastewater and sludge is likely to cause some odor problems through the rest of this week, Klemm said.
Other ongoing work at the site includes the addition of air lines and diffusers into one of the pre-aeration ponds.
Jeremy Anderson, vice president of Design Tree Engineering and Land Surveying, told city councilors at a meeting Monday that the list of things left to do at the site keeps getting shorter.
The Minnesota Pollution Control Agency has been at the facility to conduct its inspections, he said, and one of the last pieces of the process, water balance testing, should wrap up by early November.
“Things seem to be going well out there, and everything seems to be working well,” he said.
The vast majority of the work should still be complete by the original Oct. 31 date.
Despite some earlier hiccups that delayed the project this past spring and contributed to a serious odor problem, Klemm said the contractors were now mostly on schedule and “should be substantially complete” by the deadline.
The major expansion project will increase the facility’s storage capacity by 83 million gallons per day, an amount that is expected to meet the city’s needs for years into the future.
Crews with Magney Construction have been working on the project since November.
