Stop first if

  • Sewage or water touches live electrical parts.Keep clear. Shut off power only from a remote point, and only if it can be done without risk. Call a licensed electrician.
  • Anyone is about to enter a tank or treatment unit.Stop. Nobody goes in. Call emergency services if someone is inside or down.
  • Effluent is on the surface.Keep people away and treat it as sewage. Call the service provider or health department.

  2. Is an alarm on, or has it been switched off?
  3. Do you have a service contract and recent inspection records?
  4. Was there a power outage, cold snap or vacancy?
  5. Has any chemical or unusual waste gone down the drain?
  6. When was the unit last pumped?
