3 Things To Consider When Installing A New Septic Tank

Posted on

Nothing is meant to last forever and this theory applies to various parts of your home and everyday life. Your septic system, for example, has a lifespan of between 25 and 30 years, so there will come a time when you need to replace yours even if it is properly maintained. Thankfully, help is available when you are ready to replace your septic tank. Here are a few things to consider when preparing for the installation of a new tank.

Tank Type

Before you can start the installation process, you need to choose what type of septic tank you will be installing. There are many size options to consider and the right size will depend on a few factors, including your home's size, layout, and the number of bathrooms and people in your household.

Obviously, if you have a larger home and larger family, you will want a larger septic tank to ensure it can handle the volume and stress. You also want to select a septic tank size that will work with the rest of the septic system's components. Or, you may need to upgrade other elements of the system including pipes and drains. If you have a pump, you may need to upgrade this, as well.


The installation of a septic tank or septic system is invasive and somewhat overwhelming. Because of the large and extensive process, contacting your city or county officials is recommended to determine if permits must be pulled.

In addition, consider reaching out to neighbors and your HOA if you have one of these organizations. Pulling permits and receiving approval from the city/county officials and your neighborhood organization will ensure the project is completed in an effective, efficient, and proper manner without legal ramifications.


Even if you are replacing an existing tank with the same size or shape of tank, you need to make sure the layout and surrounding landscape can accommodate the new tank and connecting components.

When first installed, shrubs and trees, for example, may not have affected the septic system. Over time, though, the roots from these plants and trees most likely grew and spread throughout the ground, potentially coming near or making actual contact with your tank and septic lines.

Before the new septic system installation, removing these shrubs and trees may be necessary to reduce the risk of root damage. This can prevent leaks, septic failure, and costly repairs in the future.
