Septic systems can vary in price depending on the size of the tank, and whether or not you already have a leach field installed. Generally, you can expect to pay around $3,000 for a new septic system installation.

Septic system installation cost varies based on a number of factors: the size of the tank, the distance from the tank to the house, type of soil, and local permits and regulations. Generally speaking, you can expect to pay around $3,000-5,000 for a septic system installation. Homeowners should also be aware that they are responsible for maintaining their own septic system, which includes regular inspections and pumping of the tank as needed. Pumping a septic tank costs around $75-125 per visit.
