The department reviews wastewater construction permit applications to determine that plans and specifications for wastewater sewer systems and treatment facilities are complete with regard to the minimum requirements. The department also reviews the application to determine if the proposed construction is acceptable with regard to accepted design standards for wastewater systems to protect the public health and the environment.
Engineering Workshop
We will be hosting a Wastewater Engineering Workshop on Oct. 17, 2025. You may attend the event either in-person or virtually through video conference. This workshop is targeted to engineers designing wastewater treatment facilities. Don't miss this free opportunity to earn some PDHs, network with MoDNR staff and other engineers and expand your construction permitting knowledge.
