About 1/4 of homes in North America use a septic tank to collect wastewater from the house. Septic tanks typically last about 20 to 30 years before they need to be replaced. Here’s what to expect during septic tank installation in Flowery Branch, GA.

Parts of a Septic System

The most important parts of your septic system are your tank and drainfield.

Your septic tank is the receptacle where waste from your house is stored. In the tank, the sludge and solid matter sinks to the bottom while scum floats to the top, while the relatively clean water in the middle is released into your drainfield.

Your drainfield is a large pit in your yard full of gravel and covered with soil and grass. It is set up to allow water to be released slowly into the soil. This process naturally filters impurities out of the water, so by the time it returns to the water table, it is free from contaminants.


The cost of your septic system installation will depend on the size of your tank and the size of your home. For a small house, expect to pay around $3,000-$4,000 for the installation. For larger houses or ones with more complicated septic systems, it may cost more than $10,000. If you can reuse parts of an old septic system, your installation can cost significantly less.

The Installation Process

The first step of installation is to get a permit for your new tank, as well as an inspection from the health department. These will tell you what type of tank you can have on your property. Next, you will work with a septic tank company to determine what size and style of tank works best for your house.
If you are replacing an old septic system, the next step is to remove the old tank and pipes. Or, if you’re having a new system installed, the installation team will dig 2 holes in your yard: one for the tank and a large one for the drainfield. They will also need to lay down pipes connecting your septic system. This process may also involve removing tree stumps and other obstacles.
Installing your tank typically takes several days to complete. Keep in mind that you will probably not be able to use the water or septic system in your house during this time.

Inspecting Your Tank

Once your tank has been installed, you will need a final inspection from the health department. This is to make sure that the tank measures up to all local regulations, keeping your home and neighborhood safe. They will usually inspect your tank within a few days of installation.
