Georgia Septic Installer Practice Test

According to normal household waste composition, what percentage of the wastewater is liquid?

1. 90%

2. 99%

3. 99.9%

4. 100%

The correct answer is: 99.9%

The correct response indicates that approximately 99.9% of household wastewater is liquid. This high percentage reflects the nature of typical domestic waste, which primarily consists of water mixed with various soluble and suspended solids. In a standard household setting, most of the wastewater generated comes from sources such as sinks, showers, and toilets. While there are solid components in the waste, such as food particles or human waste, these constitute a very small fraction of the total volume. The overwhelming majority, therefore, is made up of liquid, which includes both the water used and any dissolved substances within it. The numbers represent common estimates in water quality and wastewater management practices. Recognizing that nearly all of the wastewater is liquid helps in understanding how septic systems and wastewater treatment facilities are designed to handle and process this predominant liquid component efficiently. This knowledge is crucial for anyone involved in septic system installation and management within Georgia, as understanding both the composition and volume of wastewater influences system size and type considerations.
