Septic By The Numbers – American Septic Statistics

Chances are good that most of us have experienced a so-called “frequency illusion” at some point in our lives. We notice something for the first time—a car model, a fashion trend, or even a popular phrase—and then, out of nowhere, we seem to notice it again and again. Once we’re exposed to something new, we start to see it everywhere even if it’s not as common as we might think. 

Chances are equally good that those of us who live on municipal sewer lines fail to notice how popular septic systems truly are in America today. By contrast, homeowners with a septic system likely see other septic systems just about everywhere they go. 

This leads us to an interesting question: how common are septic systems in the United States? In what regions are they most used? And how do they compare in cost to municipal alternatives?  

Here’s a rundown of septic systems by the numbers.

Land of the Free

The versatility and efficiency of septic systems makes them a popular choice for many Americans who live outside of large metropolitan areas. But the number of American households relying on septic systems today may surprise you.

According to a 2013 sewage review by water resource website Growing Blue, nearly 25% of America’s households rely on septic systems. That means that roughly 26 million households and 60 million people trust septic systems to treat their waste and wastewater every day. This trend continues in new developments as well with roughly 33% of all new nationwide developments relying on decentralized water treatment technology. 

Septic usage is not equally distributed throughout the United States, however. Regionality plays a large part in septic reliance.

Region By Region

Despite its popularity as a supposed “rural alternative” to municipal sewer lines, septic systems are common in both densely populated and sparsely populated areas. Like the number of septic households in America, the regional breakdown of septic usage is surprising and flies in the face of many common myths about septic prevalence.

According to Circle of Blue, an online outlet for water news, the highest concentration of septic systems can be found in the New England region where over 51% of new homes are built with septic systems. By contrast, in the East South Central region (comprising Alabama, Mississippi, Tennessee, and Kentucky) nearly 36% of new homes built after 1990 came equipped with septic systems. 

The Mountain region (made up of states between Texas and California) is the least reliant on septic systems with only 6% of new homes being constructed beyond a municipal sewer line. If nothing else, this regional breakdown of septic usage contradicts the common myth that only rural homes require alternative waste management systems.

Waste is Money

For many Americans, the usual monthly expenses include a water or sewage bill. Septic owners, meanwhile, can anticipate pumping their tank every 3-5 years. But beyond the monthly sewer bill and occasional pumping, how do costs stack up between sewer and septic?

When buying a home with a septic system, most of the work has already been done. While new septic systems can cost anywhere from $3,000-$10,000, this figure is usually included in the cost of a new home. The cost of pumping every 3-5 years usually runs in the area of $275 to just under $600 depending on tank size. 

Monthly sewer and water bills depend largely on where you live. But on average in 2021, American households can expect to pay:

  • For water: between $17 and $68 a month ($204-$816 annually)
  • For sewer: between $14 and $135 a month ($168-$1,620 annually)
  • For water over 3 years: $2,448
  • For sewer over 3 years: $4,860
  • Combined over 3 years:  $7,308

It should be noted, however, that these figures are an average estimate of costs when living on a well-operated, municipal sewer and water system. Repairs, breakages, and poor municipal spending can all drastically increase these costs without warning. 

In fact, water bills have been steadily rising since 2019, and as of February, 2020, Corpus Christi, TX, residents have the highest utility bills in the nation with sewer and water adding up to $215 a month, $2,580 annually, and  $7,740 over a 3-year period. 

While septic owners can expect to pay for pumping every few years and other repair costs as they arise, septic is clearly the more affordable of the two.

By the Numbers

Septic systems are more common, popular, and affordable than many of us previously thought. Given their simplicity, ruggedness, and reliance on natural bacteria and soil science, septic systems are truly a marvel of modern waste management engineering (despite being invented in the 1860s).
