The interaction among the factors discussed previously in the past articles on topography, color, texture, structure and consistence determines, in part, the loading rate for the onsite system. Loading rate is the quantity of effluent applied to the soil treatment area expressed as volume per area per unit time (e.g., gallons per square foot per day).
A site with finer texture, poor structure, poor consistence, horizons that restrict water movement, or shallow depth to a limiting condition should be assigned a lower loading rate. This will limit the amount of water that can be accepted into the soil, and thus a
