Frequently asked in St. Louis

What is the purpose of a septic tank?

A septic tank is the primary component of an on-site sewage treatment system. Its main function is to collect all wastewater from a home, separating solids, liquids, and scum. Solids settle to the bottom as sludge, while lighter materials like grease rise to the top. Bacteria in the tank help to break down some of these organic solids. The liquid effluent then moves to a drain field for further treatment.

The cost of a septic tank system in St. Louis can vary significantly based on factors like tank size, material, and the complexity of installation. Site preparation, including excavation and soil type, also plays a major role in the overall expense. For an accurate estimate tailored to your specific needs and property, getting a quote from a local professional is recommended.

How long do septic tanks usually last?

A properly maintained septic tank system can typically last for 20 to 30 years, and sometimes even longer. Regular pumping every 3 to 5 years is crucial for its longevity, along with avoiding the disposal of harmful chemicals and non-biodegradable items.
