Also known as perc rate. It is the average amount of time in minutes that the soil takes to absorb 1″ of water from a percolation hole (6 holes approx. 6″ in dia. are used for the testing and their results are averaged). This number combined with your daily water usage (gallons per day) are the two primary factors that decide the minimum size (in square feet) requirements.
