Typical Septic Tank System

A septic tank system collects wastewater from a building and separates it into three layers:

Scum Layer: Oils, grease, and floating waste rise to the top.

Effluent: The middle liquid layer flows to the drainfield for natural soil filtration.

Sludge Layer: Heavy solids settle at the bottom and require periodic pumping.

Key Components:

Inlet Pipe: Carries wastewater into the tank.

Baffle: Controls flow and prevents scum from leaving the tank.

Outlet Pipe: Transfers treated effluent to the drainfield.

Drainfield: Filters and safely disperses wastewater into the soil.

A properly maintained septic system protects groundwater, prevents pollution, and ensures efficient wastewater treatment.
