Septic systems may not be the most glamorous aspect of home ownership, but they’re very much essential, especially across large parts of the United States of America where many municipal sewer lines are simply unable to reach homes. In many states, septic tanks are the unsung heroes of wastewater management, with the ability to serve millions of homes and businesses.
At Wholesale Septic Supply, we help thousands of customers every year across the U.S. keep their septic systems running with affordable, high-quality septic components and parts delivered efficiently, so you know you can count on us when you need us most. With this in mind, it begs the question: where in the United States are the highest concentrations of septic systems, and what does that mean for homeowners, contractors, and suppliers? We answer all of that, and more, in our latest post from our team of experts at Wholesale Septic Supply!
The prevalence of septic systems varies widely across the U.S. depending on:
Population density
Availability of public sewer infrastructure
Geographic and soil conditions
Local and state building codes
Age of housing stock
Rural areas will always dominate septic system usage, yet many suburban areas, and even urban fringe communities may rely on them too, depending on the area itself. Whether you’re managing an older property or installing a new septic system, Wholesale Septic Supply is your one-stop resource for septic parts, guidance, and fast shipping.
