Septic Systems During a Disaster

Flood conditions can cause a number of potential problems for users of private sewage treatment (septic) systems. This Web page contains links to information that can help you prevent - or resolve - flood related sewage problems.

Quick Tip

Stop using your sewage system if:
    • your septic tank or drainfield becomes flooded;
    • you can see any raw sewage or "grey water" on the surface of the ground, as a result of waste water leaking from your system; or
    • wastewater begins to enter your home through drains or plumbing fixtures.
