Concrete vs. Plastic Septic Tanks: Which One Should You Install?

If you're building a new home or replacing an aging septic system, choosing the right septic tank is a decision that shouldn't be taken lightly. Among the most common options available are concrete and plastic septic tanks, both of which have distinct advantages and disadvantages. Your choice will impact not only the performance of your system but also its longevity, maintenance needs, and overall cost. A reliable septic system is crucial for keeping your household running smoothly and your property safe and sanitary.

In this blog post, our professionals from Metro Septic Pumping will talk about the pros and cons of concrete and plastic septic tanks to help you decide which option is the best fit for your home and your long-term needs.

Durability and Longevity

When it comes to strength and lifespan, concrete septic tanks tend to lead the way. Made from reinforced concrete, these tanks are highly durable and can last for several decades when properly maintained. Their weight helps prevent them from shifting in the ground, even in areas with high groundwater levels or loose soil. Concrete is resistant to external pressure, which reduces the risk of collapse or damage from heavy vehicles driving over the area.

Plastic septic tanks, while lighter and easier to install, don’t always offer the same level of durability. They can be more susceptible to damage during installation or if the ground shifts. In some cases, plastic tanks can float or become dislodged if groundwater levels are especially high and the tank isn't properly anchored. However, advancements in plastic manufacturing have improved their strength, making them a viable option in certain environments when installed by a qualified septic company.

Ease of Installation

If you're looking for a quicker and less expensive installation process, plastic septic tanks may be the better option. Their lightweight material makes them easier to transport and position, requiring less labor and heavy machinery compared to concrete tanks. This often results in a lower initial cost for homeowners, especially when working with a septic service that specializes in fast and efficient installations.

Concrete tanks, on the other hand, are heavy and require special equipment to move and set in place. This can lead to higher installation costs and longer setup times. However, the extra effort may be worth it if your property conditions favor the stability and strength of concrete. The best septic company will evaluate your site to recommend the most appropriate tank for your situation.

Maintenance and Septic Service Requirements

No matter which type of tank you choose, regular septic pumping and cleaning in Atlanta, GA are necessary to keep your system working efficiently. Concrete tanks generally require less frequent attention when it comes to structural issues, but they can develop cracks over time, especially if the surrounding soil settles or tree roots encroach. If a crack forms, it can allow wastewater to leak out or groundwater to seep in, leading to performance problems and potential environmental contamination.

Plastic tanks don’t crack in the same way, but they are prone to warping or punctures if exposed to external stress. They also require vigilant monitoring to make sure that the tank remains properly anchored in the ground. Routine inspections and septic service appointments are essential for both tank types to ensure early detection of any issues and to prevent expensive repairs down the line.

Cost Considerations

In terms of upfront cost, plastic septic tanks are generally more affordable. The lower material and transportation costs, coupled with the simpler installation process, make them attractive to budget-conscious homeowners. However, long-term costs can add up if the tank requires more frequent maintenance or repairs.

Concrete tanks may come with a higher initial price tag, but their durability can offer savings over time. Less frequent structural issues and better resistance to environmental stress can mean fewer service calls and less worry about major repairs. That said, every property is different, and a trusted septic company can help you calculate the true cost of ownership for both tank options.
