Our professional Environmental Public Health Specialist (EPHS) administers on-site sewage ordinances in Phelps and Maries County.
County ordinances adopt Missouri's state laws and minimum construction standards (Chapter 701.025 through 701.059 RSMo and 19 CSR 20-3.060 through 19 CSR 20-3.080) by reference, and regulate the installation and major repair of on-site sewer systems in the area.
The department also investigates complaints regarding the improper operation of on-site sewer systems.
Property owners must submit an application and obtain a construction permit from the department prior to constructing a new on-site sewer system or making major modifications to an existing system. Some exemptions to the laws and standards exist for residential applications, depending on acreage. Also, certain sewer systems are regulated by the Missouri Department of Natural Resources pursuant to the Missouri Clean Water Law.
The application needs to contain detailed design and component specifications for the proposed sewer system as well as a soil morphology report or percolation test results for the site. A soil morphology report provides the most comprehensive information regarding soil properties and overall site suitability. Once a construction permit is issued, the sewer system must be installed or repaired to all applicable county and state construction standards by either the property owner or a state-registered installer. The Missouri Department of Health and Senior Services (DHSS) conducts installer training and certification classes.
