What is not included in a standard disposal system?

In the context of a standard disposal system for On-Site Sewage Facilities (OSSF), gravel-less pipes are considered innovative alternatives rather than a standard component. A conventional leach field typically comprises gravel trenches designed to distribute effluent into the soil, while a septic tank is crucial for the primary treatment of sewage. A distribution box is also a standard element, facilitating the even distribution of effluent from the septic tank to the leach field.

Gravel-less pipes can be used effectively in some modern systems, but they do not constitute a standard element in traditional OSSF designs. As a result, while they serve specific purposes and may be applied in some installations, they are excluded from the conventional definition of a standard disposal system. Understanding this distinction is essential for anyone working with OSSFs, as it emphasizes the traditional components critical for system functionality and compliance.
