What is hydraulic loading?

Hydraulic loading refers specifically to the rate at which wastewater enters a septic system. It is a critical concept in septic system design and management because it affects how well the system can treat the sewage and wastewater generated by a household or facility.

An appropriate hydraulic loading rate ensures that the septic system can function effectively; if the inflow of wastewater is too high, it may overwhelm the system, leading to improper treatment and potential system failure. This measurement is essential for determining the required size of the septic tank and the drain field because it helps to ensure that the system can accommodate the volume of wastewater being produced. Therefore, understanding hydraulic loading is crucial for maintaining a reliable and efficient septic system.
