Georgia Septic Installer Practice Test

When calculating the reserve volume for dosing tanks, what measurement is taken from the top of the invert inlet?

1. To the bottom of the tank

2. To the top of the alarm system

3. To the water level

4. To the outlet pipe

The correct answer is: To the top of the alarm system

The reserve volume for dosing tanks is crucial to ensure that there is sufficient capacity for proper function and to prevent system failure. When considering the reserve volume, the measurement taken from the top of the invert inlet to the top of the alarm system is particularly important. This is because the alarm system is designed to indicate when the tank is nearing its maximum capacity, providing a critical warning to prevent overflows and potential environmental contamination. This measurement helps in defining the emergency reserve capacity needed in the system. By ensuring the reserve volume calculation starts at the invert inlet and extends to the alarm system height, it accounts for both operational and safety parameters. If the level rises to the alarm point, maintenance or corrective action is needed, which is essential for the safe and effective operation of a septic system. This way, the system can be monitored for proper function and timely interventions can be made to address issues.
