Pump Your Septic Tanks Regularly

One of the most important things you can do to keep the system functioning properly is to have the septic tanks pumped regularly. If you don't pump regularly, scum and sludge could build up and be carried to the drainfield. This will clog the drainfield and not allow wastewater to be treated, and wastewater could form a pond in the yard or back up into the house! At this point, you would be facing costly repairs or replacement, instead of minimal maintenance expenses. 

Follow these guidelines:

  • Have your septic tank pumped by a licensed pumper every 3 to 5 years.
  • Know the location of your septic tank lid(s) or riser(s). 
    • If you aren't sure where your septic system is located, check our OnBase system, which has previous site plans and well, septic, building inspection, and soil erosion permits. For best results, only enter the street # and search: www.washtenaw.org/permitrecords 
  • With a 2-tank system or 2-compartment tank, pump the first tank or compartment every 3 to 5 years, and pump the second tank or compartment every other time.
  • Keep the cover(s) easily accessible to the pumper. A marker may help you identify the area.
  • Have the pumper inspect the outlet device each time the tanks are pumped.
  • Do not wash or disinfect the septic tank after it has been pumped.
