Failing Septic Systems

How can I prevent a septic system failure?

  • Regular maintenance is the best method to prevent a septic system failure. Septic maintenance includes inspecting the entire system every 1 to 3 years and pumping the tank every 3 to 5 years. The frequency for pumping the septic tank depends on the tank size, number of people in the household, the water habits and use, if a garbage disposal is used, and the amount of solids accumulated in the tank. A rule of thumb is to pump the tank when the solids are two-thirds of the volume in the tank. Routine maintenance is the responsibility of the home or property owner. If you rent a home, you have responsibility for the proper use and operation of the system.
  • In general, you can avoid a septic system failure by:
    • Inspecting your system every 1 to 3 years
    • Pumping the tank every 3 to 5 years or as needed
    • Avoiding excess water use (e.g. spreading out laundry use over the week)
    • Flushing only human waste and toilet paper down the toilet.

What are common signs of a failing septic system?

  • Water and sewage from toilets, drains, and sinks backing up into the home’s plumbing
  • Bathtubs, showers, and sinks draining very slowly
  • Gurgling sounds in the plumbing system
  • Standing water or damp spots near or over the septic tank or drainfield
  • Sewage odors around the septic tank or drainfield
  • Bright green, spongy lush grass over the septic tank or drainfield, even during dry weather
  • Straight pipe discharging untreated wastewater to the ground surface
  • Algae blooms in nearby lakes or waterbodies
  • High levels of nitrates or coliform bacteria in surface waters or drinking water wells
