How Do Septic Tanks Work?

A septic tank is an underground wastewater treatment system that homeowners in areas without established sewer systems rely on to treat wastewater from their homes. It combines the power of nature and proven water treatment technologies to ensure that wastewater coming from bathrooms, laundry, and kitchens is safely released back to the environment. To keep your septic tank operating efficiently, you need to understand how it works and ensure that it is regularly inspected and emptied by a professional septic tank expert such as Septic Tanks North West.

Components of a Septic System

Typically, a septic system is comprised of three main parts: a pipe carrying wastewater from the house, an underground septic tank, and a leach field, also known as a drain field. The wastewater flow relies on the force of gravity, while the digestion of the organic matter in the tank depends on the activity of anaerobic bacteria.

How a Septic Tank Works

As mentioned earlier, a septic system is basically meant to treat wastewater from a household. The process involves three basic steps, as explained below.

Step 1: Waste Water Flows into the Septic Tank

All wastewater from a house is directed to a pipe leading it to the septic tank. The flow of wastewater from the house to the septic tank relies on gravity.

Step 2: Activities in the Septic Tanks

The septic tank is a watertight tank buried underground. It is usually made of fibreglass, polyethene, or concrete. When the wastewater gets into the septic tanks, anaerobic bacteria start breaking down the organic matter in the wastewater. The tank has to hold the wastewater long enough for the solids to settle at the bottom to form sludge. On the other hand, less dense matter such as oils, greases, and fats rises to the top to form scum. The liquid wastewater then joins an exit pipe with the filter in the tank preventing solids from leaving. The solid waste can then be removed by a licensed septic tank company, such as Septic Tanks North West.

Step 3: Activities in the Drain Field

The wastewater from the septic tank flows into a drain field. In the drain field, the remaining organic matter is broken down by aerobic bacteria. The relatively clean wastewater then drains into the ground to replenish groundwater reserves. As the wastewater percolates into the ground, any harmful pathogens are naturally removed.

The Takeaway

As you can see, septic tanks are not as intimidating as they sound. Although they can cost homeowners a little more compared to the public sewerage systems, they help people in areas without central sewage treatment facilities to discharge their homes’ wastewater in the safest way possible.
