What is a Septic Tank?

A septic tank is a large container that is buried underground. It is used to treat and dispose of waste from toilets, sinks, and showers in houses that are not connected to a city sewer system.

How Does It Work?

  1. Waste Arrival: When you flush the toilet or drain water, the waste flows into the septic tank.
  2. Separation: Inside the tank, the waste separates into three layers: solids sink to the bottom (called sludge), liquids stay in the middle, and lighter things (like grease) float on top (called scum).
  3. Bacteria Action: Bacteria in the tank help break down the solid waste into smaller pieces. This process is called decomposition.
  4. Filtering: The liquid waste then flows out of the tank through pipes into a drain field, where it gets filtered by the soil and eventually absorbs into the ground.

Why are Septic Tanks Important?

Septic tanks are important because they help keep our environment clean. They treat waste safely and prevent contamination of groundwater, which is the water we might drink!

Remember!

It’s important to take care of septic tanks by not flushing anything that can’t be broken down, like wipes or plastic. This helps the tank work properly for a long time!
