What type of work is classified as a repair on an onsite wastewater system?

The classification of a repair on an onsite wastewater system typically involves restoring functionality or efficiency to a system that has failed or is malfunctioning. Enhancements that are aimed at improving the overall performance of the system fall under this category because they usually involve modifications or solutions that address specific issues related to the operation of the system.

Routine cleaning of the system generally refers to maintenance practices designed to prevent failure or keep the system operating correctly, rather than repairing an issue that already exists. Replacing soil around the system might be a part of maintenance or a necessary action due to environmental concerns but does not equate to actual repair work on the system's functionality. Upgrading to a more complex system suggests a significant change or improvement beyond mere repair, often involving new installations rather than fixing existing problems.

Thus, enhancing system performance fits the definition of repair, reflecting necessary actions to ensure the onsite wastewater system operates as intended after experiencing issues.
