Flow equalization is a design and management concept that can help reduce stress on system performance due to high peak flows. In flow equalization; the peak flows are stored for a period of time to be delivered to downstream components, including the soil treatment unit, over a longer period of time.
Flow equalization systems are more commonly found in systems with advanced pretreatment and in facilities with variations in flows, which are found in many commercial systems. With commercial systems, the septic tanks are still sized based on the peak flow, but the downstream components can be sized based on the
