What is the required septic tank capacity for each bedroom?

The required septic tank capacity for each bedroom is determined by guidelines established for proper wastewater management and to ensure the tank can adequately handle the volume of sewage generated by the household. In North Carolina, the standard requirement is a minimum of 120 gallons of septic tank capacity per bedroom.

This capacity ensures that there is sufficient space to accommodate the daily wastewater produced by each person residing in the home, allowing for adequate settling of solids and effective treatment of the effluent before it enters the drain field. Ensuring the proper capacity is essential for maintaining system functionality, preventing overflow, and protecting the environment by avoiding contamination of groundwater.

By setting the requirement at 120 gallons per bedroom, it accounts for variability in water usage and provides a buffer to ensure that even during peak usage times, the septic system can perform effectively.
