A typical residential septic tank is usually around 4.5 feet wide x 8.0 feet long x 6 feet tall, though this is just a jumping-off point, as many tanks exceed this size. The average tank clocks in at 30 to 40 square feet.
How Large Is a Septic Tank?
A septic tank is an essential part of any home or commercial property. It is an underground container that captures and contains wastewater from a building. Septic tanks are typically made of concrete, fiberglass, or plastic and come in a variety of sizes. The size of a septic tank is determined by the number of bedrooms in the home or commercial property it services.
In general, a septic tank needs to be large enough to contain the amount of wastewater generated from the building it is servicing. This means that the larger a building is, the larger the septic tank must be. For instance, a three-bedroom home will typically require a septic tank that can hold up to 1,000 gallons of wastewater. The size of the tank increases incrementally as the number of bedrooms in the home increases.
The size of a septic tank can also be impacted by the type of wastewater it needs to contain. For instance, a septic tank that needs to contain wastewater from a commercial property or an industrial operation will need to be larger than one that only services a residential property. This is because the wastewater from commercial and industrial operations tends to contain higher levels of pollutants and solids that must be contained.
