As a licensed full-service provider we install new systems, provide proper maintenance, service and repairs on existing conventional and aerobic septic systems.

Aerobic System Installations

Your septic system is one of the most important decisions you can make for your home or business. Think about it, once the system is buried it is practically permanent. Problems can be messy and expensive to resolve. That is why we take the time to help you understand the the entire installation process and make sure your system is designed to meet your needs now and in the future.

  • I had a contract with another company. They took our money but never did anything. A friend recommended Tri-County Septic. They actually show up and do what you pay for. The inspector alerted me to a potential problem. Tri-County sent a crew to repair the problem before it could cause a larger issue."

  • I called around and got pricing for the septic system at our new place. Tri-County Septic not only gave me a fair price, but took the time to explain the different types and manufacturers to help me decide what system would work best now and in the future. The process was smooth and we could not be happier in our new home.
