A septic tank is a crucial component of an on-site wastewater treatment system. Its primary purpose is to separate solids from liquids in household wastewater. Solids settle to the bottom as sludge, while lighter materials like grease float to the top as scum. The liquid effluent then flows to a drainfield for further treatment. It's the first line of defense in safely managing your home's wastewater. We ensure your tank functions effectively.
