Gravity Flow Sewage Treatment

At least three feet of permeable soil must be present in order for a gravity fed system to be the appropriate choice.


How Does Gravity Flow Septic System Work?

Just as you might suspect, a Gravity Flow Septic System relies on gravity to carry wastewater from the house to the septic tank.

  1. Wastewater and sewage flow through an inlet baffle and into the underground Septic Tank.
  2. Bacteria inside of the septic tank begin the organic treatment process by eating harmful pathogens.
  3. Solids sink to the bottom of the septic tank and form a Sludge Layer
  4. Grease, oils and light material float to the top of the septic tank where a Scum Layer is formed.
  5. Liquids form an Effluent Layer in the middle of the septic tank where it is allowed to flow out through an outlet baffle.
  6. An Outlet Baffle Filter provides a good barrier to keep solids from traveling out and possibly clogging up the outlet baffle.
  7. A Distribution Box is typically used to distribute the liquid waste into pipes located in the drainfield.
  8. The Drainfield contains pipes with small holes where liquids can drain into a gravel trench.
  9. Partially treated wastewater seeps into the Soil Treatment Area for the final stage of treatment before reaching groundwater.
  10. Oxygen loving Bacteria living in the soil, remove harmful pathogens.
