Which Septic Tank is Right for Your Site?

If you're looking to install a septic tank, there are several factors that you need to consider. It's important to evaluate the soil conditions, site topography, and water table level. All of these factors can have a significant impact on the functionality of the septic system. That's why it's always advisable to hire a professional septic company for septic tank installation. It's not a good idea to install a septic tank yourself because you're more likely to make costly mistakes.

Here at Septic Blue of Charlotte, we specialize in installing different types of septic tanks. Let's look at some of the factors to consider when installing a septic tank to help you determine the right one for your site.

  • Soil Conditions

The type of soil on your property determines how well it absorbs treated wastewater from the tank. Sandy or loamy soils with good drainage are ideal. A septic professional will conduct a soil test to determine suitability.

  • Topography

The slope and layout of your land are important considerations when it comes to septic tank installation. Ideally, your property should have a gentle downward slope from the house towards the drainfield location to avoid the need to install a lift station. Moreover, the septic tank should be positioned strategically so that it allows for a gravity-fed inflow pipe. A septic professional will assess your site's topography and advise you accordingly.

  • Water Table Level

This is one of the most important considerations when you're installing a septic tank. If your site has a high water table, it could hinder proper drainage from the drainfield and cause water source contamination. 

  • Local Regulations

The local regulations will also determine the type of septic tank you can install on your property. Each locality has regulations governing septic system installations. These regulations dictate factors like tank size, drainfield design, and minimum distances to wells and property lines. It's important to adhere to all local requirements to ensure a compliant and functional septic system.

Common septic tank materials

  • Concrete

Concrete is one of the most popular materials used to construct septic tanks. If you look around your neighborhood, you'll notice that a significant number of septic tanks are made from concrete material. Many homeowners prefer concrete due to its exceptional strength and durability.

  • Fiberglass

Fiberglass is an ideal material for those looking for a lighter option. Fiberglass septic tanks are not only easy to install, but they are also resistant to corrosion.

  • Steel

Steel is incredibly strong and can withstand significant weight and pressure from the surrounding soil. However, steel septic tanks are susceptible to rust over time, especially if the protective coatings are compromised. If you have a steel septic tank, it's important to keep a close eye on the condition of the protective coatings and take the necessary action. It's also important to schedule regular septic tank pumping and septic tank cleaning.

  • Plastic

Septic tanks made from plastic are relatively affordable and easy to install, but they may not be as durable. Besides, they can be susceptible to damage from external pressure or environmental factors.

Each one of the materials we've highlighted comes with its advantages and downsides. The right septic tank for your site will depend on the factors we've already highlighted and the recommendations from septic professionals. When it's time to install or replace a septic tank, let trusted septic technicians perform a comprehensive site evaluation to determine the right septic tank for your property.
