In towns and cities, the local sewage treatment plant handles wastewater filtration and disposal. In rural settings, on the other hand, homeowners need their own individual wastewater treatment plants in the form of a septic system. Rural property owners often find themselves asking, “How much does a septic tank cost, and why is it so expensive?”

Your septic tank installation cost depends on many factors, such as the system’s site, size, and style. In addition to recurring costs for maintenance and repairs, these variables determine the overall price.

Tank Site

It is critical to first consider the site itself when planning a septic system installation. When you factor in the costs of site preparation and construction permits, tank location becomes a key determiner in the total expenses. Additionally, plumbing to and from the site can significantly the overall septic system cost, as every 100 feet of PVC pipe for septic systems costs an average of $65 to $80.

Tank Size

The treatment method you want to use and the size of the tank you need are the next points to consider. Aerobic wastewater treatment methods are more effective and significantly more expensive, while aerobic septic treatment systems need a larger leaching field. Increases in tank size also significantly increase your septic tank installation cost. The most common septic sizes for septic tanks are between 1,000 gallons and 1,500 gallons.

Tank Style

Tank materials make a big difference in cost. Most septic tanks are made of plastic, concrete, or fiberglass, although polyethylene tanks are prohibited in some states. The last factor to consider is the tank design itself. Repairs from a flawed design cost more over time than hiring a professional septic system designer. Have a professional engineer design your system; even if it adds cost, the money is well spent.

If you’ve ever wondered, “How much does a septic system cost?” You’ll know there are many other factors that can affect prices for septic tanks and septic systems. These are simply the main factors with the greatest impact on the cost of septic systems. Once you have a good idea of the site, size, and style you need, you’ll be able to answer the question.
