This blog includes two different septic tank size tables to determine the required size or capacity you need for your septic tank.
How big does your septic tank need to be?
Typically the septic tank volume for a conventional tank and drainfield is estimated at a minimum of 1000 gallons or 1.5 x average total daily wastewater flow.
Also important to know is what the smallest recommended septic tank sizes can be based on building occupancy or wastewater volume.
How big does our septic tank need to be based on the number of bedrooms in the home?
Some jurisdictions use the number of bedrooms rather than number of occupants or estimated daily wastewater flow to guide homeowners and septic installers in choosing a septic tank size.
