Subsurface sewage treatment system (SSTS) compliance inspections are conducted for:
- Newly installed or replacement systems — To determine if the design and installation meet code requirements, and if the system will protect public health and minimize effects on groundwater. Inspectors also look at whether the system is designed for longevity, ease of maintenance, and reliability.
- Existing systems — To determine whether the system is functioning properly to protect public health and groundwater. Existing system inspections do not check for system size, horizontal setbacks (i.e., property lines, wells, and buildings), estimated longevity, current usage, or past system abuse.
Individuals conducting compliance inspections must be certified by the MPCA and either operate under an SSTS inspection business license, or act as a qualified employee of a local government.
