What Size Septic Tank Do I Need?
If you are in the market for a new septic tank, you may be wondering what size you need. This can be a difficult question to answer, as it depends on a variety of factors.
In this guide, we will discuss some of the things that you need to consider when determining the size of your septic tank. We will also provide some tips on how to choose the right size for your needs.
What is a Septic Tank?
A septic tank is a watertight chamber made of concrete, fiberglass, or plastic. It is used to treat wastewater from toilets, showers, sinks, and washing machines. The septic tank filters the sewage and breaks down the solid waste.
The septic tank size will depend on the number of bedrooms in your home, the type of soil, and the amount of wastewater you produce.
How to Choose the Right Size Septic Tank?
The most important factor to consider when choosing a septic tank is the size of your home. The tank should be able to hold the wastewater from your home for at least 24 hours.
Here are some other factors to consider when choosing the right size septic tank:
The type of soil on your property
The type of soil on your property will play a role in the size of your septic tank. If you have sandy soil, you may need a smaller tank, as it has a high rate of percolation. If you have clay soil, you will need a larger tank, as it has a low rate of percolation.
Consider your water usage
When it comes time to select the size of your septic tank, you need to consider how much water your household will use on a daily basis. The average person uses 80-100 gallons of water each day, but if you have a large family or like taking long showers, your usage could be higher than that.
The amount of water you use will have a direct impact on the size of the septic tank you need. If your household uses more water, you’ll need a larger septic tank to accommodate the increased usage. Conversely, if your family is small or has low water usage, you can get away with a smaller septic tank.
The number of bedrooms in your home
The number of bedrooms in your home will help you determine the size of the septic tank you need. For one to two-bedroom homes, a 300-gallon tank should be sufficient.
If your home has three or more bedrooms, then you will need a 500-gallon tank. Keep in mind, these are just guidelines. Your specific needs may vary depending on the size of your home and the amount of wastewater it produces.
The age of your home
The age of your home can also play a role in the size of the septic tank you need. If your home is more than 20 years old, it may be time to replace your current system with a larger tank.
Features of your home to consider
There are some additional features of your home that you should consider when choosing the size of your septic tank. Here are some of them:
- Multiple dishwashers
- Two kitchens
- Low-flow appliances
- An indoor spa, hot tub, or swimming pool
- Waterfall showers
Consider house size
The square footage of your house is a good way to consider the right size septic tank for you. A 2000 square-foot house will need a different size tank than a 1000 square-foot home.
Why is Septic Tank Size Important?
The size of your septic tank is important because it needs to be able to accommodate the wastewater produced by your household. If you choose a tank that is too small, it will quickly become full and will need to be emptied more frequently.
If you choose a tank that is too large, you will be wasting money on an unnecessarily large tank. It is important to choose the right size septic tank for your needs.
The Main Types of Septic Tanks
There are three main types of septic tanks:
1
Concrete septic tanks
A concrete septic tank is a large, cylindrical tank made of non-corrosive materials. It is usually buried in the ground, and has an access cover for periodic maintenance.
2
Fiberglass septic tanks
A fiberglass septic tank is a newer type of septic tank that is made from fiberglass-reinforced plastic. It is lighter and easier to install than a concrete tank, but it may not be as durable.
3
Steel septic tanks
A steel septic tank is the most traditional type of septic tank. It is made of heavy-gauge steel and is buried in the ground. Steel septic tanks are very durable, but they may rust over time.
