- Sealing a crack in a tank lid;
- Repairing or replacing a tank baffle or access manhole riser;
- Repairing or replacing a pump or electrical switch;
- Leveling a distribution box;

Repair does not include:
- Replacement, reconstruction or modification of a tank or soil absorption system;
- Extension or enlargement of a soil absorption component and system;
- Replacement of a distribution pipe; or
- Repair or replacement of a metal or concrete block tank.
Repairs and maintenance can be performed on an onsite wastewater treatment system that functions properly without being subject to the registration and design requirements of Title 124 if:
- The repair is to fix a minor structural defect of the existing system such as: to seal a crack in a tank lid; level a distribution box; or to repair or replace a manhole riser, inspection pipe, tank baffle, building sewer pipe, or a pipe between the septic tank and soil absorption system; or
- The repair is to fix a mechanical device, such as repair or replacement of a pump, blower, or electrical equipment.
Only a certified professional, a professional engineer, a registered environmental health specialist, or a person under their direct supervision, may engage in the repair of an onsite wastewater treatment system. “Direct supervision” means the person overseeing the work is physically present on the site where the work is being done and has control over, responsibility for, and professional knowledge of the work being done.
