Georgia Septic Installer Practice Test

What percentage of the total interior volume of the absorption lines does the volume of the dosing tank need to be?

1. 40-50%

2. 50-60%

3. 60-75%

4. 75-85%

The correct answer is: 60-75%

The answer pertaining to the required percentage of the total interior volume of the absorption lines that the volume of the dosing tank needs to be is based on the principles of effective septic system design. For optimal performance, the volume of the dosing tank should be 60-75% of the total interior volume of the absorption lines. This range ensures that there is sufficient capacity in the dosing tank to adequately manage and control the flow of effluent into the absorption lines. It allows for effective dosing, which is crucial for proper distribution and prevents potential issues such as overloading the absorption area, which can lead to system failure. By adhering to this percentage, the design facilitates adequate absorption of effluent, promoting proper treatment and minimizing the risk of contamination or system backups. When considering other ranges, such as 40-50% or 50-60%, these might not provide enough volume in the dosing tank to effectively manage the flow, while percentages higher than 75% could create an imbalance in the septic system design, potentially leading to issues with adequate effluent dispersal.
