The Sioux Center Water Department provides quality water to 2,536 customers drawn from local aquifers and treated to exceed all federal and state standards.


The Water Department is responsible for operating the collection, treatment and distribution facilities that provide water to the community. Specific duties include:

  • Cleaning, disinfecting and repairing the 16 wells that provide raw water
  • Operating the water treatment plant
  • Overseeing installation of water infrastructure in new subdivisions
  • Performing routine maintenance and repairing valves and hydrants on the distribution system

Sioux Center has two primary sources for its water - a shallow alluvial aquifer and a buried channel aquifer. Wells located in each of the aquifers pump raw water to the treatment plant, where iron and manganese are removed and chloramine disinfection occurs. Sioux Center Municipal Utilities switched to chloramine disinfection in 2022. More information on chloramine disinfection.

The water treatment plant is capable of treating 1,600 gallons per minute. The water utility serves 2,536 customers.
