Since inception in 1999, the Iowa Onsite Waste Water Association (IOWWA) works to educate its members and public about the benefits of quality onsite wastewater treatment. IOWWA is one of the largest state organizations in the country focused on the onsite wastewater industry. Our members number more than 400 and include regulators, installation contractors, maintenance contractors, soil scientists, engineers, manufacturers and educators. These people join to make IOWWA a diverse and well-balanced organization.

IOWWA's main goal is to expand on industry-wide education. The primary means is by supporting training workshops across the state. Workshops are held several times per year and cover subjects including site evaluation, system design, and system installation. IOWWA provides other educational opportunities by publishing our quarterly newsletter and by hosting an annual conference. The two-day annual conference features seminars by nationally recognized experts, peer discussions, networking opportunities, and exhibits featuring the latest technologies and services.

Membership in IOWWA supports the IOWWA Scholarship program.    Also, your paid dues include membership in NOWRA for the "Primary" IOWWA member.   The primary member will receive all the benefits of NOWRA including a subscription to the “Onsite Journal” and the quarterly NOWRA newsletter.  

IOWWA grows stronger with new and renewed memberships. You are invited to join IOWWA as we work to learn and share knowledge in our industry.   Please accept our invitation by completing the membership application form posted at this site. You can also contact Penny Andorf, Association Administrator at 515-225-1051 or by email,
