What is the hydraulic loading rate for Soil Type 6?

The hydraulic loading rate for Soil Type 6 is 0.2, which reflects the percolation capacity of very coarse soils such as sands and gravel. This value is critical as it helps determine how much water can be safely applied per unit area without causing saturation or oversaturation, which can lead to failure of the septic system.

In lower permeability soils, like Soil Type 6, the introduced water can pass through the soil matrix at a slower rate. Knowing the hydraulic loading rate allows for the correct sizing of the system to promote proper wastewater treatment and prevent environmental contamination. The rate of 0.2 is established based on hydraulic conductivity and is vital when assessing effluent disposal methods, ensuring that the groundwater is protected and the septic system functions efficiently. Understanding this aids septic pumper professionals in making informed decisions regarding system design and maintenance practices.
