Let’s look at the differences between septic and sewer systems.

What Is A Septic System And How Does It Work?

A septic system is an on-site wastewater treatment system that is used to treat and dispose of wastewater. It consists of a septic tank and a drainfield, which is an area of soil that is used to filter and treat the wastewater. When wastewater flows from a house into the septic tank, the solid waste settles to the bottom of the tank and is broken down by bacteria. The liquid wastewater then flows out of the tank and into the drainfield, where it is further treated by the soil before being absorbed into the groundwater. A septic system can be more cost-effective than a sewer system, particularly in rural areas.

What Is A Sewer System And How Does It Work?

A sewer system is a network of pipes that carry wastewater from multiple homes and businesses in an area. The wastewater flows from homes and businesses through pipes and into larger sewer lines, which transport the wastewater to a treatment plant. At the treatment plant, the wastewater is treated and disinfected before being released into a river or other body of water. A sewer system provides a centralized approach to wastewater treatment; hence, it’s suitable for densely populated areas.

What Are the Differences Between Septic and Sewer Systems?

A septic system is owned, operated, and maintained by the individual property owner, while a sewer system is owned and operated by a municipal or regional authority. When it comes to wastewater treatment, a septic system enables property owners to treat wastewater on-site within the septic tank and drainfield. In a sewer system, wastewater is treated at a centralized treatment plant. In terms of capacity, a septic system is designed to handle the wastewater of a single household or commercial property, while a sewer system is designed to handle the wastewater output of an entire area.
