If the system is particularly difficult to access or requires repairs to internal components like baffles or filters, the labor time increases. We provide exact pricing confirmed free on the call.

About this service

When you need a new system, local experts handle the entire process from soil testing to permitting and final setup.

Frequently asked in St. Louis

What is the purpose of a septic tank?

A septic tank is an underground wastewater treatment system that handles sewage from homes not connected to a municipal sewer. It separates solids from liquids, allowing solids to settle as sludge. The liquid then flows to a drain field for further natural purification by the soil. This system is vital for sanitation and environmental health.

What is the average cost of a septic tank?

How long do septic tanks usually last?

With consistent maintenance, including regular pumping and avoiding flushing harmful substances, a septic tank system can last for 20 to 30 years, or even longer. The drain field's lifespan is also significant and depends on proper usage and installation. Regular check-ups are key to ensuring longevity in the St. Louis climate.

How often do septic tanks need to be emptied?

In the St. Louis area, it's generally recommended to pump your septic tank every 3 to 5 years. This frequency can change based on the tank's capacity and the number of people using the system. A professional can assess your household's usage and tank size to advise on the best pumping schedule.
