Construction is rolling on major parts of Sioux Center’s new wastewater treatment plant.
“We are on schedule moving toward the 2020 completion date to meet the new, more stringent DNR standards,” said Utilities Manager Murray Hulstein.
In early June, a crew poured 1,000 yards of concrete to create the floor of the plant’s aeration basins. Now workers are forming up the aeration basin walls. These basins are a new element for the community’s treatment plant. They are part of the phosphorus and nitrogen removal process, which was not previously part of Sioux Center’s system.
“This process is part of meeting the new DNR standards,” said Zeke Ellis, Sioux Center Wastewater Department head. “This plant is designed to handle what our community needs today and for the next several decades.”
In addition, the concrete for the primary clarifiers have been poured. These clarifiers will help remove floating and settled solids from the wastewater.
The concrete basement of the operations building is poured. Work has also begun on the pretreatment building walls and the biosolids building, which will hold 2 million gallons.
The new plant is being built just west of the existing plant, near the intersection of 13th Avenue and 20th Street SE. Plans call for the plant to be operational by mid-2020.
“This plant is designed to serve Sioux Center in a stewardly manner, improving our environmental impact today and with continued growth in our community,” Hulstein said.
The City of Sioux Center’s sanitary sewer system collects and treats wastewater produced by more than 2,000 residential, commercial and industrial customers and is paid for with user fees from these customers.
