Georgia Septic Installer Practice Test

Which of the following statements about septic tank size is true?

1. Septic tanks can be any size as long as they fit the backyard

2. Septic tanks must be at least 1500 gallons

3. Septic tanks must be at least 1000 gallons, with a tolerance of +/- 4%

4. Septic tanks should be 2000 gallons for all properties

The correct answer is: Septic tanks must be at least 1000 gallons, with a tolerance of +/- 4%

The statement regarding septic tank size being a minimum of 1000 gallons, with a tolerance of +/- 4%, is accurate. This requirement is designed to ensure that septic systems can effectively handle the wastewater generated by a household. The minimum size of 1000 gallons provides adequate volume for separation of solids and liquids, which is crucial for proper treatment and to prevent overloading the system. The tolerance of +/- 4% allows for some flexibility in construction and installation, accommodating potential variances in design and manufacturing. This regulation is grounded in health and safety standards, ensuring that septic systems function efficiently and do not pose a risk of contamination or system failure. Understanding these specifications helps installers and homeowners maintain compliance with local regulations and achieve functional septic system design. The other options present incorrect information regarding septic tank requirements. Some suggest arbitrary sizes that do not align with established guidelines, while others imply a one-size-fits-all approach, which is not applicable as septic tank sizing must be tailored to the specific needs of the property and its anticipated wastewater volume.
