What does maintenance of an OSSF typically exclude?

Maintenance of an On-Site Sewage Facility (OSSF) generally focuses on the upkeep and operational efficiency of the system, which includes routine checks, cleaning, and inspection to ensure everything is functioning correctly and remains compliant with regulations. Routine sediment removal is also a crucial part of maintenance, as it helps prevent blockages and maintains the system's efficiency.

Alterations to the existing system are excluded from routine maintenance. While it is possible that modifications may be necessary over time due to changes in use or the expansion of a property, such alterations require more extensive planning, potential engineering assessments, and regulatory approvals. These activities go beyond standard maintenance tasks and include significant changes to the system's design or layout, which is why they are not considered part of regular maintenance.
