Septic System Failure and Emergencies

During a flooding event, water can enter your system and force solid materials into the drain field or create a sewage back-up. 

During a flood:

• Stop using your toilets, sinks, showers, and any appliances that drain water.
• Do not send any floodwater into the septic system and drain field.
• Shut off any portion of the system with electrical components.
• Avoid working around the drain field with heavy machinery while the soil is wet.

After a Flood

• Test your well water.
• Look for sewage backups or pooling.
• Clean and disinfect areas exposed to sewage.
• Avoid driving or digging in the drain field until soil has dried.

When Soil Has Dried

• Have a licensed professional inspect the system and drain field.
• Inspect electrical components for damage and ensure they are dry.
• Test the system to confirm it is functioning properly.
• Conduct any repairs if needed. 

Wildfires can weaken or damage septic system components. 

After a fire:

• Observe whether piping, risers/covers, cleanouts, vent pipes, and drain field inspection ports are melted or charred.
• Look for evidence of vehicle traffic near the septic system, especially the drain field.
• Look for damage where the septic pipe enters the home.
• If you suspect septic system damage, test your well water and contact a septic professional for an inspection and any needed repairs.

Power outages can affect your system if it relies on pumps, electrical timers, or other electrical components. Gravity systems typically continue to function during an outage, but systems with pumps will stop moving wastewater. During this time, wastewater will collect in the tank and must be safely dispersed once power is restored. 

During the outage: 

• Reduce water use:
  • Take short showers
  • Limit laundry and dishwashing
  • Turn off the tap while brushing teeth, shaving, or rinsing dishes
  • Avoid flushing every time for liquid waste
• Turn off the pump at the control panel. This will keep the pump from automatically turning back on once the power is back.

After Power is Restored: 

• Inspect your system and call a professional if you see any damage, exposed wiring, unusual odors, or signs of sewage backup.
• Follow the instructions for your specific system type to safely disperse wastewater that built up during the outage.
• Continue to reduce water use until the system is operating normally.
