Sioux City asks for study of wastewater, proposed changes


Chances are you used a sink, or flushed a toilet today, but it's something we don't always think about.

That used water is considered wastewater and gets special treatment before its released back into the environment.

Sioux City's Public Works Director Jade Dundas said the state of Iowa is taking a further look at regulating things that may be harmful to the environment making their way into wastewater.

And, because of the state's initiative, Sioux City hired their own consultant to do a study assessing the cost and what it would take to implement the removal of harmful elements in our water system.

The city said they are already ahead of the game at the Wastewater Treatment Plant in Sioux City because during their last upgrade, they added nitrogen removal.

But, Dundas said it's important to go forward with this study for several reasons.

"It's important for us to just be environmentally conscious. Everything we do in Sioux City impacts the water quality downstream. Others are using that water for recreation, maybe even a source of drinking water," Dundas said.

Those who work down at the Wastewater Treatment Plant said more regulations creating cleaner water are a good step for the state and the current study will help them be ready whenever they get the go-ahead to add phosphorous removal.

"We know the regulations are coming. If we get in there and look at this now and determine what our costs are going to be, we can prepare taxpayers, council, and also it gives us the information, we can sit down and possibly negotiate with DNR for relaxed standards, which saves everyone more money in the long run," Wastewater Treatment Plant Superintendent Jay Niday said.

Plant superintendent Jay Niday said other communities in Iowa have gone through similar studies. He said these areas are using their data to negotiate with the DNR.

Niday said there is space for the upgrades at their current plant.

Dundas said the study could take up to 6 months.
