Cost to build a septic tank

The septic system is an underground tank that holds sewage and waste water. It is buried in the ground, where it filters and cleans the water before it flows into the ground. The septic system consists of a drain field (also called leach field) consisting of one or more laterals (or pipes) that carry wastewater from the house to the main tank.

The septic system cost depends on various factors like size of the house, soil types and terrain etc. The average price for a septic system costs $2,100.

A complete septic system includes all components like leach field and drain field along with a separate grease trap for each line, which means two lines will be needed for two bathrooms. However, there are some things that you can do to reduce your costs and make sure that you get value for money.

The type of system: There are three main types of septic systems—drywells, leach fields, or seepage beds—each with different costs associated in design, construction and maintenance.

Your contractor’s fees: Contractors generally charge between $1,500 and $2,000 per installation depending on the size of your home and whether they use their own equipment or subcontractors.

The average cost for a septic tank is $2,000 to $4,000. A larger tank costs more because it holds more waste, which must be pumped out every few years. Smaller tanks are less expensive because they don’t hold as much waste. They also require less maintenance and pumping services.


The cost of building a septic system varies from state to state and even county to county due to geographic differences in construction costs such as land prices and labor rates. For example, constructing a new septic system in Colorado may cost as much as $10,000 while installing one in California could be as little as $3,000 or less depending on whether you’re installing an above ground or underground system
