The primary purpose of the certification credential is to set a standard of practice and create a baseline of knowledge for onsite wastewater system installations. Iowa counties are encouraged to adopt regulations providing for licensing of installers and to require CIOWTS certification. Counties currently requiring the CIOWTS credential are Benton, Black Hawk, Bremer, Buchanan, Butler, Chickasaw, Dallas, Delaware, Floyd, Grundy, Jasper, Jones, Linn, Marion, Scott, Story, Warren, Washington, and Winneshiek. Please check with your county sanitarian for specific requirements. Iowa County will require the credential as of Jan. 1, 2019.
The CIOWTS credential runs on a two-year cycle. During each two year cycle, the credential holder must have a minimum of 12.0 hours of continuing education earned in the onsite wastewater industry. IOWWA has events scheduled throughout the year that provide continuing education approved for the CIOWTS credential. For those taking the Installation Overview course prior to a scheduled test, the 12.5 CE hours earned will be applied to the first two-year cycle.
