The size of septic tank required in a home depends on factors that include the number of people in the household and the amount of waste generated in a day. Septic tanks are the most common sewage treatment systems for people living far from communal sewage systems.
Size is one of the most essential pointers when planning for septic tanks and field lines. In many areas in the United States, the minimum size of septic tank required for a home is 1,000 gallons. A homeowner can also use the number of bedrooms in the home to calculate the size of septic tank needed.
