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.

Joining IOWWA now will establish your membership until the end of 2018.   The IOWWA membership structure is designed to accommodate companies and government entities of any size.   If one person is active then the “One Primary Active Staff Person” membership at $100.00 is the best choice.     Companies with numerous active individuals will benefit from the "Multiple Active Staff Persons" membership.   For this membership, there is one (1) primary person ($130.00)  That person will receive the newsletter and NOWRA membership.  An unlimited number of additional staff can join for $60.00/each.   All association activities have both member and non-member fees.

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.

IOWWA can help you address issues and answer questions specific to onsite wastewater treatment in our state. IOWWA is also connected to the National Onsite Wastewater Recycling Association (NOWRA), the premier national organization focused on the onsite wastewater industry.    Membership in IOWWA includes 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”, the quarterly NOWRA newsletter.   Membership dues in IOWWA also support the IOWWA Scholarship  program.

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.
