Septic systems manage wastewater for homes that aren’t connected to a city sewer line. It includes two key components that work together to treat and dispose of household wastewater efficiently.

The Septic Tank: First Stop for Wastewater

The first component is the septic tank. This watertight container receives everything from your home’s toilets, sinks, and drains. Once inside the tank, solids settle at the bottom to form sludge. Oils and grease float to the top, creating a layer of scum. Between these layers, the liquid effluent remains and flows out of the tank for further treatment.

The Drainfield: Natural Filtration at Work

The second part of the system is the drainfield, also called a leach field or disposal field. Effluent from the septic tank travels through underground pipes set in gravel or sand-filled trenches. The soil naturally filters the water as it percolates through. This step removes harmful bacteria and contaminants before returning the treated water to the groundwater.

Why Septic System Knowledge Matters

Knowing how your septic system works is the first step to keeping it in good shape. Routine inspections and timely pumping can prevent costly repairs, protect your property, and keep your home running smoothly.
