Purdue Residential Onsite Wastewater Disposal:  Septic system information to protect your family and the environment
 

Maintaining Your System

There are several things you must do to maintain your septic system: 
  • Have a professional pump out your septic tank every three to five years.

  • Get a professional!
     
     

  • Take notice when the system begins to back up. Possible causes of septic system failure include:
    • Tank needs pumped
    • Tree roots have grown into trenches
    • Pipe has burst
    • Trenches are too wet due to large amounts of rainfall

    Take notice when the system backs up!
     
     

  • Reduce the amount of water used. This can be done in many ways such as using low-flow devices, detecting and repairing leaky faucets and toilets, washing larger loads of laundry instead of many small loads, and eliminating other wasteful water use habits.

  • Do larger loads of laundry
     
     

If you do not maintain your septic system, it is likely to fail. A failed septic system can pollute drinking water, both yours and the entire community. Once the drinking water supply is polluted, it is very hard to clean up.
