Code of Ethics for IOWWA Certified Installers

A long time goal of the Iowa Onsite Waste Water Association (IOWWA) has been to promote and offer certification to members. The primary purpose of the certification is to set a standard of practice and create a baseline of knowledge for onsite wastewater system installations. Counties throughout the state of Iowa are encouraged to adopt regulations providing for licensing of installers and to require certification through IOWWA. Obtaining the CIOWTS and IOWWA certification is a significant personal accomplishment and it also can give the applicant an edge over the competition by showing a commitment to maintaining a higher standard of professionalism.

IOWWA has entered into an agreement with the National Environmental Health Association (NEHA) to use its Certified Installer of Onsite Wastewater Treatment Systems (CIOWTS) exam as a base for offering IOWWA installer certification to its members.

Persons desiring to take the exam must apply to NEHA. IOWWA will sponsor the exam at its annual conference or at other times as the need arises. There are two levels of certification that can be achieved - basic and advanced. Applicants must achieve a minimum test score of 70%.

* Exam fees are payable to NEHA at time of application for exam. (For the exam member rate you must be a member of NEHA or NOWRA. All IOWWA members are members of NOWRA)

Upon successful completion of the exam applicants may apply to IOWWA for certification as an installer of onsite wastewater treatment systems by submitting the application and code of ethics forms posted above. In order to maintain their IOWWA certification, applicants must complete of a minimum of 18 contact hours (clock time) of continuing education. This education must be provided by or approved by IOWWA.
