Cost to Install Septic System



Not all homes have a septic system systems but those who do have them because there is no connection to the main sewage pipes that the government manages. This could be because you are way out in the country or you are a private corporation. If you are looking into purchasing a new home, it’s important to know if you have a septic tank or not. They can be very expensive to fix and manage since the local government doesn’t provide any funds for your private septic system.

Factors of Cost

There is a very wide price range for replacing a septic system due to the multiple models, sizes, and type of septic system you have in your home. Older and smaller models start from no less than $2,000 but the more expensive, larger septic systems could go as high as $20,000 not including installation.

A major role in the cost of installation is your location. Different contractors will charge different installation fees that vary by thousands. In a less populated state such as Montana, the installation cost between $3,000 and $6,000 but a more expensive state such as California could cost more than double that.

There are more expensive systems which include peat filters or aerobic systems which are more on the pricey side costing as much as $15,000. That is why it is important to know what type you currently have so you can budget for a replacement one if it breaks.


Many states have information for their residence that include pricing for various septic systems offered in the area. States like Rhode Island state that the average system will cost between $10,000 and $20,000. Texas has a broader range between $4,000 and $15,000.

Additional Costs

If you don’t already have a septic tank on your property but you are looking into having one built, your county will need to provide you with a permit. Building permits are only a fraction of the cost of the entire project, averaging around $250.

Installing a septic system can be a messy process, ruining surrounding landscaping and plants. The cleanup will not be included in the cost and will be up to the property owner to cover. The cost of plants and damaged property will vary depending on the damage done.

An after care cost of owning a septic system is crucial to prolong the life of your system. Every three years a cleaning is recommended which could cost around $100 per cleaning. Besides just the cleaning, there are also various maintenance costs including filters and pumps.

Ways to Save Money

Taking care of your system in the short term will save hundreds of dollars in replacement parts in the future. Preventative care will lessen wear and tear over the years.

Installation of a septic system will cost thousands but there are ways to save some money. Splitting the costs of using the drain field or absorption system with your neighbors will save everyone some money. Since more than one house can be hooked up to the system, you should save yourself at least a third of the costs of installing and running the system.
