Septic systems play an integral role in every home, and often, homeowners know very little about how they work. Understanding septic system function is an important part of septic tank care. Familiarizing yourself with the process will ensure you avoid common pitfalls and stay on top of maintenance. Below, you’ll find all the basics of home septic system operation.

How Home Septic Systems Work

Down the Drain

The septic system is actually part of your plumbing. Whenever something is flushed down a toilet or drain, it travels through your piping to reach the septic system. This is why it’s so important to be mindful of what you flush. Items like grease, hygiene products, paint, and non-soluble chemicals and oils can damage piping, leading to costly repairs.

Into the Septic Tank

Once the wastewater reaches the septic tank, it will be treated by bacteria. Wastewater, referred to as “effluent,” fills the tank. Countless anaerobic bacteria live in your septic tank, and they’re responsible for breaking down the effluent.

Waste that’s heavier than water will sink to the bottom of the tank. Anything lighter, such as fats and oils, will rise to the top, forming a scum layer. Once treated by bacteria, the wastewater will flow into the drain field. Filters are added to the outlet pipe to prevent solid waste from passing.

Into the Drain Field

Unless your septic system is connected to a municipal sewer, waste will be ejected into a drain field. This area is an often-overlooked part of septic tank care. The drain field, located on your lawn, will absorb the water and filter it.

It will then be reused and return to the water table. When chemicals are flushed, they can be ejected into the drain field and create problems with the soil. Parking or building over the drain field may compress the soil. You should also avoid planting over it so you don’t create problems.
