What Type of Septic System Do I Have?: Dry Well Septic

  • Do I have a drywell septic?Wastewater flows from the home or business into a septic tank.
  • Solids settle on the bottom of the tank, while less dense materials, such as grease, oils and soap, float to the top.
  • The liquid in the middle of the tank (“wastewater”) flows under baffles that prevent soap and grease from entering the septic drywell.
  • The wastewater flows via a pipe into the drywell, usually a tall concrete cylinder that has holes in the sides and an open bottom, covered in soil.
  • The wastewater then seeps out into the surrounding soil, which filters the effluent.
