About This Show
AI-drafted summaryThe IOWWA Annual Conference is the flagship educational and trade event of the Iowa Onsite Waste Water Association (IOWWA), a nonprofit dedicated to advancing the onsite (septic) wastewater industry across Iowa. The 2027 edition marks the association's 28th Annual Conference, combining a multi-track technical program with a trade show floor showcasing the latest equipment and treatment technology.
The conference draws septic system installers, service providers, pumpers, designers, soil evaluators, precast concrete and tank manufacturers, regulators, and county sanitarians. Sessions deliver continuing education relevant to Iowa's CIOWTS (Certified Installer of Onsite Wastewater Treatment Systems) program, along with regulatory updates from the Iowa DNR and Iowa One Call.
Attendees come for practical, field-focused learning on site evaluation, soil suitability, tank technology, pump sizing, control panels, trench safety, and Time of Transfer inspections. The event pairs classroom education with a hands-on exhibit hall, the popular Roe-D-Hoe excavator contest, a President's Reception, an auction, and strong networking among Iowa's onsite wastewater professionals and suppliers.
