Question

Quizplus · Accepted Answer

Septic tanks are the most commonly used systems in rural and suburban areas to treat raw sewage on personal property. They are effective in breaking down organic matter and separating the liquids from the solids. The liquid wastewater then flows out to a drain field where it is absorbed into the soil, while the solids remain in the tank to be pumped out periodically. Other options such as living machines and compost toilets are less commonly used and may have limitations in terms of effectiveness or maintenance requirements. Primary and secondary sewage treatments are typically used in larger scale municipal systems rather than individual properties.
