What is a Septic Tank?
A septic tank is a crucial component of a decentralized wastewater treatment system, primarily used in rural and suburban areas where municipal sewage systems are unavailable. It is an underground chamber made of concrete, fiberglass, or plastic that collects and treats wastewater from a home. The tank operates on a simple principle: it separates solids from liquids, allowing the effluent to flow into a drain field for further treatment and absorption into the soil.
How Does a Septic Tank Work?
When wastewater from sinks, toilets, and showers enters the septic tank, it undergoes a natural process of separation. Heavier solids settle at the bottom, forming a sludge layer, while lighter materials, such as grease and oils, float to the top, creating a scum layer. The middle layer, which consists of liquid effluent, is what exits the tank and flows into the drain field. Here, the effluent is further treated by soil microorganisms, which break down harmful pathogens and nutrients before the water re-enters the groundwater system.
The efficiency of a septic system relies on proper maintenance, including regular pumping of the tank to remove accumulated sludge and scum. Homeowners must also be mindful of what goes down their drains, as certain substances can disrupt the delicate balance of bacteria needed for effective treatment.
