Missouri Smallflows Organization provides quality onsite wastewater education in Missouri. Over 250 people are in attendance each year and it continues to grow.
Missouri Smallflows Organization is the largest professional onsite wastewater association in Missouri. Our members consist of installers of onsite wastewater systems (septic systems), inspectors, onsite soil evaluators, regulators, and engineers. Our organization is governed by a Board of Directors elected by the membership. We strive to bring quality educational opportunities to onsite wastewater professionals of Missouri. Annual Conference and Trade Show: We host an annual Conference and Trade Show every year in January. We host the annual Roe-D-Hoe® where the winner qualifies for the National Roe-D-Hoe® at the National Onsite Wastewater Recycling Association (NOWRA) Conference. The Conference not only brings in great regional speakers but a large Trade Show with over 35 Exhibitors from the onsite wastewater industry. Continuing Education: MSO provides continuing education classes throughout the state for professionals to keep their state issued licenses. These classes are approved by the Missouri Department of Health and Senior Services (Missouri DHSS). Our classes are held to the highest standard to provide quality, un-biased information about onsite wastewater treatment technologies. Membership: Our organization is supported by over 500 members. Our members take advantage of lower priced classes to keep their continuing education classes up and receive a quarterly newsletter. We are constantly researching new ideas to grow our member benefits. In addition, our members can have the opportunity for their son or daughter to apply for the annual Daryel Brock Memorial Scholarship. Join our organization and help us progress onsite wastewater technologies in Missouri. Thank you for your support!
