The answer to 'septic tank or septic tank' is that a septic tank and a septic tank are the same thing. A septic tank is an underground wastewater treatment system used in areas without access to a municipal sewer system. It is a crucial component of an onsite sewage facility that collects, treats, and disposes of household wastewater and sewage.
Septic tanks come in various sizes and materials, such as concrete, plastic, or fiberglass, and are typically installed underground on the homeowner's property. They work by allowing solids to settle and decompose, while the liquid effluent is then dispersed into a drain field or leach field, where it is further treated and filtered into the soil.
