KEOTA – The city of Keota could be nearing an overhaul of their water treatment system.

The city announced in a social media post that the Iowa Department of Natural Resources (DNR) has required the city to address chloride levels associated with its wastewater discharge. City officials say that chloride is difficult to remove once it enters the wastewater system, so it is necessary to look at where the chloride is coming from: one major source is the ion-exchange water softening used by the city, which requires approximately 8,000 pounds of salt every month.

Keota mayor Ryan Carr said that the city is currently working with engineers to evaluate their options, which include the construction of a new water treatment system, continuing to operate their current system with necessary improvements, and converting Keota to a rural water system.

Preliminary estimates indicate that the total cost of addressing the water system could reach $5 million. Construction would likely begin sometime in 2027 or 2028.

No official decisions have been made regarding the potential water treatment system overhaul, but Carr says that funding sources could include some combination of water rates, property taxes, grants, and low-interest financing.

Carr added that as engineering studies and cost estimates become more complete, the city intends to share that information with the public and provide opportunities for residents to ask questions and learn about alternative options.
