You may have heard the myth that septic tanks are not common. However, septic tank systems are more popular than you might think, especially in Middle Tennessee and other parts of the South. More than 21 million American households use a septic system. That’s about 20% of homes in the United States that have a septic system instead of a public sewer to trap and filter toilet waste.

If your house has a septic tank, you may be wondering how a septic tank system works, when you should have it serviced, and how often. 

According to the U.S. Environmental Protection Agency (EPA), four major factors influence the frequency of septic pumping: 

  • Household size
  • Total wastewater generated
  • The volume of solids in wastewater
  • The size of your septic tank

How Often Should I Have My Tank Inspected?

The EPA advises that the average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years. The EPA also states that alternative systems with electrical float switches, pumps, or mechanical components should be inspected more often, generally once a year. 

When you have a professional septic service company inspect your tank, they check for safety, deterioration, holes, cracks, correct water levels, and overall condition. However, the University of Minnesota has a great Septic Tank Pumping Frequency Guidelines chart you can fill out ahead of time to get an idea of how often you should have your tank inspected and pumped before you call a septic service provider.
