Septic Tank Questions, Answered

What is the purpose of a septic tank?

A septic tank is an underground wastewater treatment structure. Its primary purpose is to receive wastewater from a building, separate solids from liquids, and allow for partial decomposition of the solids. This process removes a significant portion of pollutants and solids from the wastewater before it flows to a drain field for further treatment and dispersal into the soil.

How long do septic tanks usually last?

Septic tanks are designed for longevity. With proper maintenance, including regular pumping and avoiding system damage, a septic tank can last anywhere from 20 to 50 years. The lifespan is influenced by factors such as the tank's material, the soil conditions, usage patterns, and the quality of the initial installation. Regular inspections can help identify potential issues early.

How often do septic tanks need to be emptied?

Septic tanks typically need to be emptied, or pumped, every 3 to 5 years.
