Frequently asked in St. Louis

What is the purpose of a septic tank?

A septic tank is the primary component of an on-site wastewater treatment system. It receives all wastewater from your property, allowing solids to settle and form sludge. Bacteria then begin to break down this sludge, and the liquid effluent moves to a drain field for further purification in the soil.

What is the average cost of a septic tank?

How long do septic tanks usually last?

With regular maintenance, a septic tank system can last for 20 to 30 years or even longer. This includes periodic pumping and avoiding flushing harsh chemicals down the drain. Proper care is essential to prevent premature failure and expensive repairs in the St. Louis area.

How often do septic tanks need to be emptied?

Most septic tanks should be pumped every 3 to 5 years. This frequency can vary based on the number of people in your household and your water usage in St. Louis. If you notice slow drains or recurring backups, it's a strong indicator that your tank needs attention.
