Frequently asked in St. Louis

What is the purpose of a septic tank?

The primary purpose of a septic tank is to serve as a pre-treatment facility for wastewater from homes not connected to a city sewer system. It separates solid waste from liquid wastewater, allowing the solids to decompose and the liquids to flow to a drain field for further treatment and absorption into the soil.

What is the average cost of a septic tank?

How long do septic tanks usually last?

A properly maintained septic tank can last for many years, typically between 20 to 30 years. Regular pumping and avoiding the disposal of grease or harsh chemicals down the drain are crucial for extending its life. In St. Louis, consistent care is key to preventing premature failure.

How often do septic tanks need to be emptied?

Generally, septic tanks require pumping every 3 to 5 years. However, this can vary based on household size and water usage. For many homes in the St. Louis area, this recommended frequency helps prevent solids from accumulating and causing system blockages.

How much does it cost to have a septic tank pumped?

How often should a septic tank be pumped?

Most septic tanks need to be pumped every 3 to 5 years to function correctly. If your household in St. Louis has more than four members or uses a lot of water, you might need more frequent pumping. This preventative measure helps avoid costly repairs and backups.
