What Is A Septic Tank, And How It Works

If your home isn’t connected to a municipal sewer system, chances are you rely on a septic tank—a critical part of your property’s wastewater management. But what exactly is a septic tank, and how does it function?

A septic tank is an underground chamber made of concrete, fiberglass, or plastic that collects and treats wastewater from your household plumbing. When water flows from your sinks, showers, toilets, and washing machines, it travels through pipes and into the tank.

Here’s how it works:

  1. Separation: Once inside the tank, solids settle to the bottom and form a layer of sludge, while oils and grease float to the top as scum. The middle layer contains relatively clear water called effluent.
  2. Breakdown: Naturally occurring bacteria in the tank break down solid waste, helping reduce buildup and allowing more space for new wastewater.
  3. Drainfield Distribution: The liquid effluent flows out of the tank into a drain field (or leach field), where it is filtered through soil, removing harmful bacteria and nutrients before it returns to the groundwater.

For a septic system to work efficiently, it needs proper maintenance. Over time, sludge and scum build up and must be pumped out. Additionally, the bacteria inside your tank are essential to waste breakdown—this is where septic additives can play a helpful role in supporting healthy function.
