Septic Tank Pumping and Cleaning

  • A septic tank requires frequent cleaning

    • Typically, this will fall between every 24-36 months for most users

    • Lower use or low additions of organic materials may decrease the amount of maintenance needed

    • High use will increase the amount of maintenance needed

    • Healthy septic tank will have three (3) layers

      • Scum layer – Stuff that floats on water: Fats, oils, and greases

      • Clear Effluent Layer – The middle layer or pretreated waste water. Should be the only layer leaving the tank after a minimum of 24 hours of retention time.

      • Sludge Layer – The bottom layer which is the decomposed solids and organics.

    • Should be thoroughly pumped and cleaned if

      • Scum + Sludge > 25-33% of tank depth at inlet or

      • Scum > 3”

      • or Sludge > 12”

  • Whenever the tank is pumped, it should be inspected.

    • Inspection includes determining that the tank and its components are watertight, that the baffles are in place, that the tank and baffles are not crumbling and breaking, and that the overall tank operations are properly functioning.


  • With Butlers, your septic tank will be thoroughly pumped and cleaned:
