Georgia Septic Installer Practice Test

How many gallons should be added to the dosing tank for each linear foot of absorption lines?

1. 1/4 gallon

2. 1/2 gallon

3. 1 gallon

4. 2 gallons

The correct answer is: 1/2 gallon

The correct amount to be added to the dosing tank is 1/2 gallon for each linear foot of absorption lines. This measurement is critical because it helps ensure that the septic system operates efficiently and that the effluent is evenly distributed across the absorption area. Proper dosing is essential for maintaining the functionality of the absorption field by preventing over-saturation and promoting healthy soil conditions for biological treatment processes. If too little effluent is added, it can lead to poor absorption and insufficient treatment of wastewater. Conversely, adding too much can cause flooding and fail the system. The established guideline of 1/2 gallon per linear foot strikes a balance that supports effective treatment while minimizing risks associated with both under-dosing and over-dosing. Each septic system may have slightly different requirements based on design and field specifications, but adhering to this standard ensures optimal performance in the majority of installations. Understanding this principle helps in designing a septic system that is functional, reliable, and longer-lasting.
