What defines a Standard System in onsite wastewater management?

A Standard System in onsite wastewater management is defined as a system that typically uses perforated pipes and gravel for the treatment and dispersal of effluent. This configuration allows wastewater to be treated by the soil and microbial action as it passes through the gravel and surrounding soil layers. The perforated pipes distribute wastewater evenly, which helps in promoting efficient filtration and avoiding system overload.

This method is conventional in many residential settings because it effectively utilizes natural processes for wastewater treatment, ensuring proper absorption into the ground while minimizing environmental impact. By relying on the natural filtration capabilities of the soil combined with the structured layout of gravel and pipes, these systems can efficiently manage effluent in appropriate soil conditions.

In contrast, systems involving holding tanks, commercial wastewater processing, or bioswales utilize different methodologies and designs that do not align with the standard definition of a wastewater management system that employs perforated pipes and gravel.
