What is a conventional septic system?

A conventional septic system is defined as a method for treating wastewater that primarily relies on gravity to move effluent through pipes to a drain field. This design takes advantage of natural gravitational forces to facilitate the flow from the septic tank to the leach field where the effluent can naturally infiltrate and undergo treatment through soil filtration and microbial action.

In a conventional septic system, waste from the property enters a septic tank, where solids settle to the bottom and liquids flow out into perforated pipes. These pipes are typically laid in trenches within a gravel-filled drain field which allows for further treatment before the wastewater reaches the groundwater. This gravity-based operation is simple and effective for residential and some light commercial applications, making it the standard design for many septic systems.

Other options do not accurately describe conventional septic systems. For instance, systems that rely on pumps are generally classified as innovative or alternative septic systems, which are not conventional by definition. Systems specifically designed for commercial use are a separate category and may utilize advanced technology that differs from conventional designs. Similarly, while monitoring systems are important for many wastewater treatment processes, conventional systems do not require constant monitoring, as they generally function without the need for additional mechanical or electrical components. By understanding these distinctions, one can recognize why gravity-based
