What is the hydraulic loading rate for Soil Type 2?

The hydraulic loading rate refers to the amount of water that can be applied to a specific type of soil without causing saturation or runoff. For Soil Type 2, which typically includes soils such as sandy loam or similar textures, the hydraulic loading rate is determined based on its ability to absorb and filter wastewater effectively.

A rate of 1.0 (the answer provided) is optimal for Soil Type 2 as it balances the soil’s capacity to accommodate water while ensuring good drainage and treatment of septic effluent. This rate reflects the soil's ability to promote soil filtration, reduce pollutant loads, and maintain adequate moisture levels to support microbial processes essential for wastewater treatment.

Understanding hydraulic loading rates is crucial for designing effective septic systems that protect both public health and environmental integrity by minimizing the risk of groundwater contamination.
