Residential septic systems are alternatives to municipal sewers. Thus, it’s the responsibility of the homeowner to keep up with maintenance and repairs. To do so, it’s important to understand how a septic system works, as you’ll be better at diagnosing issues and discussing problems with a professional. Here’s what you need to know. 

Why Do Homeowners Install Septic Tanks?

A private septic system allows homeowners to treat wastewater in their backyard. The process is more cost-effective than using a centralized sewer system. This is because, in rural areas—where houses are often far apart from each other—a considerable amount of pipes and other sewer line materials would be needed to connect each household to a central treatment plant. As a result, residential systems are easier to install.

How Does a Septic System Work?

A septic system is made up of two primary components: a septic tank and a drain field. The former is responsible for digesting organic matter that goes down your household plumbing. This enables the separation of wastewater from solids and other matter. Bacteria in the tank and drain field break down the waste and allow clean water to enter the soil.

Water flows from your household into your septic tank via one main drainage pipe. The underground septic tank will hold the wastewater, and the bacteria will break down the organic material. Inorganic solids sink to the bottom to form sludge, while the grease and oil float to the top to form scum. The effluent, or partially purified wastewater, makes up the middle layer and will then leave the septic tank to travel into the drain field via a pipe. The drain field is a covered area where the water enters the ground.

The drain field is typically lined with coarse sand or gravel, and perforated pipes let effluent ooze into them. The presence of bacteria in gravel enables the waste to undergo natural decomposition. Clean water will then trickle into the aquifer and groundwater.
