What design requirement is mandated for septic systems with a daily flow exceeding 750 gallons?

For septic systems with a daily flow exceeding 750 gallons, it is mandated to utilize a specialized dosing system for effluent discharge. This requirement is important because higher daily flows can exceed the absorption capacity of the soil and may create a risk of system failure if not properly managed. A dosing system helps to regulate the flow of effluent and distribute it evenly over a larger absorption area or drain field.

This method ensures that the effluent is released in controlled doses rather than continuously, allowing for adequate treatment and absorption in the soil, thereby minimizing the risk of groundwater contamination and system overload. Furthermore, a specialized dosing system can accommodate the unique needs of larger volumes, making it a crucial component for septic systems designed to handle significant waste production.
