About Us


The Minnesota Onsite Wastewater Association (MOWA) was founded in 1975 to represent those individuals and companies in Minnesota whose business is involved in designing, constructing, or providing maintenance and repair service for onsite sewage treatment systems, commonly known as septic systems.

MOWA has over 400 members across the state and is a non-profit business association whose primary objective is the betterment of public health through sound principles and procedures.  MOWA provides opportunities for professionals to network and build their business.  The annual convention is a large event that brings together suppliers and contractors to learn about new technologies in the industry.

MOWA is governed by a volunteer Board of Directors.  Members of this Board are elected each year at the MOWA Convention.  Consider becoming an active voice and join the Board!
