Help with Sizing a Septic Tank

Septic tanks are an important part of life outside of city limits. If you are not hooked up to your local city’s sewage system, you must have a septic tank to filter out the sewage waste from your home. Choosing the perfect size of septic tank for your home is a somewhat complicated process, because there are many variables

Local regulations: Always read all local regulations before making any important decisions regarding your sewage tank system. Different cities and states have different guidelines for the best sized tank for your home. The size tank that you need can also vary depending on if you are adding to an existing home or building a home from the ground up. Your local regulations will help you choose the correct size for any home or commercial property.

Bedrooms: One method used for helping to determine general tank size is calculated by the number of bedrooms in your home. This data is generalized based on the average amount of water used in homes with a certain number of bedrooms. In general, the larger the house, the larger the tank will be. 1-2 bedroom homes can have a tank of 750 gallons, 3-4 bedroom homes can have a tank size between 1000 and 1200 gallons, and homes with 5 or more bedrooms require a tank size of at least 1500 gallons. Keep in mind any potential additions that you may add on to your home at a future date as well when determining tank size.

Water flow: The amount of water flow from your house is a good measurement for existing homes. The higher the water flow, the larger the tank. If you use 500 gallons a day, a 900 gallon tank is enough. But, if you use over 4000 gallons of water a day, you will need a tank size around 6000 gallons.
