Sioux Center’s new wastewater treatment plant is getting closer to the day it will begin accepting wastewater.
Members of the Sioux Center City Council toured the facility on the southeastern edge of Sioux Center last week and heard progress updates.
“All the buildings are up, and now they’re doing finish work inside – electrical, HVAC, plumbing. They’re also doing outside site piping,” said Sioux Center Wastewater Department Head Zeke Ellis. “Construction is probably more than 60 percent done.”
The new plant is being built adjacent to Sioux Center’s existing wastewater plant, an aging facility that will not meet new, more stringent DNR standards.
“We have several new processes designed into the new plant which will allow us to meet those standards and release even cleaner water. This plant is designed to serve Sioux Center for a long time,” Ellis said.
Wastewater arriving at the new plant will first be pumped through a screening process. It will then flow to anoxic basins to be processed without oxygen for nitrogen and phosphorus removal. Next it will flow into the aeration basins, where oxygen is provided for microorganisms to break down organic compounds. Water then flows to the final clarifiers where solids settle out, then it is sent through ultraviolet (UV) treatment to remove any pathogens such as E. Coli before the treated water is released.
Plans call for the new plant to be operational by 2020, ahead of the deadline for the new DNR requirements.
“It’s an immense project,” Councilman Jamie Van Ravenswaay said after the tour. “This is a big step for Sioux Center. It will be good to see it running and ready to go in 2020.”
The Sioux Center Wastewater Department serves 2,536 customers, treating an average of 1.7 million gallons of wastewater daily at the existing wastewater treatment plant southeast of the community.
