Define design flow in septic system terms.

Design flow is the estimated amount of wastewater produced each day that a building will generate and is used to size the septic system and its components. This daily volume determines how big the septic tank, the distribution network, and the leach field need to be to handle the loads without backing up or failing. It reflects typical daily discharge from fixtures and occupants, often estimated from occupancy or fixture counts per code. It’s different from how much the pump can move at once (pump capacity), from the tank’s interior volume (which relates to storage inside the tank), and from annual water usage (which averages across the year and doesn’t capture daily loading).
