​Average area of drainfield of individual septic systems

The typically recommended drainfield area per person is about 40 to 70 square meters. This varies from state to state in the United States. For a household with 2.5 people, a drainfield area of 100 square meters is generally recommended. Users can modify the area based on the number of people in a household. The parameters area and cap may be modified appropriately to study the effects of a larger population size using septic systems.
