Water Treatment System Registration Update:

On April 21st 2022, the Governor of Iowa, Kim Reynolds, signed an Act (Senate File 2232) relating to the sale, lease or rental of water treatment systems in the state of Iowa.  You can see this bill in its entirety here.  Beginning on January 1st 2023, state registration will no longer be required to sell a water treatment system in the state.   Any water treatment systems currently being sold in Iowa still require registration between now and December 31, 2022.  Any manufacturers wanting to sell new water treatment systems in Iowa between now and December 31, 2022, will need to submit a new registration application for each device to be sold in Iowa.
