By how much is the septic tank capacity increased for each additional bedroom beyond four?

1. 100 gallons

2. 150 gallons

3. 200 gallons

4. 250 gallons

The correct answer is: 250 gallons

In Georgia, the regulations governing septic systems stipulate that for each additional bedroom beyond four, the septic tank capacity must be increased by a specific amount to ensure adequate treatment of wastewater generated by the additional occupants. This regulation is critical as it helps prevent system overload, which can lead to system failure and environmental contamination. The standard increase in capacity that is required for each additional bedroom beyond the fourth is 250 gallons. This figure is based on the average wastewater generation per person, allowing for proper functionality and maintenance of the septic system. It reflects the need for additional space to accommodate the increased volume of waste that will be handled due to the extra bedrooms. The other choices represent lower increments, which would not meet the state's requirements for septic tank capacity and could compromise the system's operation and longevity. Having a septic tank that is adequately sized is essential for both health and regulatory compliance.
