Abstract
Water flow is a critical aspect of onsite wastewater treatment systems. Understanding its behavior is essential for effective system design, operation, and maintenance. This presentation covers a range of engineering principles associated with water flow in, around, and over onsite wastewater systems.  The discussion encompasses foundational elements of hydraulic engineering such as flow in pipes, water pressure, septic tank function, flow in soil pores and dispersal media, and vegetated and unvegetated open channel and overland flow. The presentation delves into the fundamental principles underlying each flow mechanism and investigates their interactions within the context of onsite wastewater treatment systems through case studies. The insights gained from this discussion can aid in understanding the mechanics of onsite wastewater treatment systems, leading to improved construction, operation, and maintenance for industry practitioners.
