Is it legal for my home's aerator system to discharge to a road ditch?
No. Although, if you have that type of system and it existed before January 1, 1996, it is exempt from inspection. You may not have to repair it unless there is a complaint from a neighbor or other affected person. However, your system could pose a threat to the health of your family and community, and to the environment. You should consider upgrading your sewage system if it discharges on the ground surface.
