A septic tank is an essential plumbing component of many homes, playing a critical role in treating wastewater and keeping a property safe and sanitary. All homeowners should understand how their septic systems operate so they can get the most dependable use out of their tanks and stay on top of any potential repair issues. To help you in this process, below are answers to common septic tank questions.

Answers to Common Septic Tank Questions

How does a septic tank work?

First, wastewater flows into the tank, where the watery elements, called effluent, fill the majority of the unit's volume. Bacteria break down the organic materials in the effluent, while the inorganic materials, called sludge, fall to the bottom of the tank. A layer of scum, typically comprised of fats and oils, rises to the top. The effluent then flows out to the drain field and into surrounding gravel, where bacteria break it down further, and the clean water seeps into the groundwater and aquifer.

Where should a septic tank be installed?

The proper placement is crucial for the safe, effective use of any septic system. The tank should be installed on level ground, in sandy soil where moisture absorption is naturally higher. Also, don't install the tank at the bottom of a hill, where it may be prone to flooding during heavy rain.

How often should I pump my septic tank?

The average septic tank should be professionally inspected and pumped at least every two to three years. During this process, a septic professional will assess liquid levels and pump solids from the tank. They will give you a report that details how your system is functioning and any repairs that may need to be done.

How long does a septic tank usually last?

A routine inspection and pumping schedule contributes to a long septic tank lifespan. A steel tank can last 15 years or more, while concrete can last 40 years and often much longer. With the right soil, drain fields can serve a septic tank well for several decades.
