Septic Tank Size

How do people figure out how big or small their septic tank should be? What logic is applied to sizing a septic tank? One of the most important factors in determining how big of a septic tank should be installed in a septic system is water usage.


You can avoid septic tank problems by ensuring your tank is made from the right material. The majority of septic tanks are constructed out of concrete, fiberglass, polyethylene or coated steel. Typically, septic tanks with a capacity smaller than 6,000 gallons are pre-manufactured. Larger septic tanks are constructed in place or assembled on-site from pre-manufactured sections.
