UPDATE: IOWWA has been in negotiations with the National Environmental Health Association (NEHA) to purchase the Certified Installer of Onsite Wastewater Treatment Systems (CIOWTS) credentialing test. As of Wednesday March 23, 2018, that goal has been reached. IOWWA is now the holding and ownership agent for the CIOWTS credentialing test. We are working to finalize the test procedures however the program will basically remain the same.
We are working to finalize a test date to be held in early June 2018 in Iowa Falls. As in the past, we will offer the Installation Overview course prior to the test however that will remain an optional choice for anyone submitting a test application. A test date will also be scheduled for Fall 2018 in Iowa County.
Please let us know if you have questions concerning this change in the CIOWTS test ownership. We are compiling a list of names for those who would like to sign up for the test so please forward your contact information to IOWWA (including email if possible) to firstname.lastname@example.org and we will contact you as soon as the June 2018 date is established.
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.
