Septic Tank Installation Considerations: Things To Know

Posted on: 25 May 2021

If you have decided to have a septic tank installed on your property, it's important that you understand the many additional decisions you'll have to make in order to actually get this project started. For those who have never dealt with septic system installation, you may not be aware of the considerations that go into choosing the tank itself. Here's a look at a few of the decisions that you'll have to discuss with your septic system installation technicians.

Tank Construction

One of the first things that you need to decide is what type of septic tank you want. There are two primary materials that septic tanks are crafted from. You can either choose a concrete tank or one made from reinforced plastic. 

Concrete septic tanks are stronger, but they can be more costly to install. The weight associated with a concrete septic tank usually means that you'll need to have the tank lowered into place by a crane, which is what will add to your installation costs. 

Reinforced plastic tanks are lighter, making them far easier to install. And modern reinforcements and construction make them almost as strong as concrete models. Your septic system installation technician can help you decide which material is the best fit for your needs and budget.

Soil Condition

Another important factor in the installation of your septic system is the condition of the soil on your property. Your septic system installation contractors will test the soil in various areas of your property to assess the soil content, drainage, and more. This is important because your soil's content and drainage capabilities will affect the style of the septic system your contractors will install.

Tank Size

When you're planning your septic tank installation, you'll also have to decide what size tank you want to have installed. Choosing your septic tank size requires careful consideration, and should only be done after discussions with your septic system installation contractor. 

There are a few different factors that go into choosing the size of your septic tank. First, the technician will consider the drainage capabilities of your property and of the system that will be installed. Then, you'll have to factor in how many people live in your home currently, because that's a direct reflection on average water consumption.

Additionally, you'll want to think about allowing for potential growth. After all, if you have a family reunion with guests for several weeks, or if your family expands, you'll want to be sure that your septic tank can handle the additional demand without significantly increasing your tank pumping frequency or risk of backups.
