Review the layout
Compare the approved field location with buildings, paving, wells and additions. Missing records may require locating work.
Look for warning signs
Persistent wet spots, sewage odors and recurring slow drains deserve evaluation. Healthy grass alone does not prove failure.
Check the rest of the system
A blocked outlet or failed dosing pump can mimic a field problem. Review the tank and delivery components too.
Understand the limits
A condition inspection cannot guarantee future drainage through every season. Additional testing or access may be needed.
Use the findings
Choose monitoring, a targeted repair or a replacement design based on the cause and the required approvals.
