Years ago, the only choice you would have for a new septic tank during replacement would've been a steel tank version, but sewage and septic processes have evolved greatly over the years, and there are now many choices. Perhaps one of the more modern choices, however, is a fiberglass septic tank. Fiberglass septic tanks, much like any other type, have their pros and cons, so it is important to get to know them before opting for this particular type. Here is a quick look at the good, bad, and beautiful of fiberglass septic tanks.
Good: Fiberglass septic tanks are lightweight.
Because of the lightweight design, fiberglass tanks are easy to maneuver and set into place. Usually, you don't even have to hire heavy equipment to install the tank on your property. On the other hand, if you go for a concrete septic tank, the installation process could require a small lift crane just to set the unit in place.
Bad: Lightweight can mean the tank will shift easier during periods of heavy ground saturation.
Bonus: Because the fiberglass tank is so easy to maneuver, installation costs are pretty minimal.
Good: Fiberglass is incredibly resilient to pressure.
Concerns that would be present with other septic tank types where above-ground weight distribution is concerned will not be an issue for the most part with a fiberglass tank. You will not have to worry about causing damage to the tank by parking something heavy directly over it and cracks caused by changes in ground temperature won't be a concern.
Bad: Unfortunately, tree roots will still be a concern with a fiberglass tank even though the tank itself is fairly resilient. The growing roots can push the tank out of place with growth because it is less hefty.
Bonus: Fiberglass is a highly resilient material, which usually means a lengthy lifespan for your new septic tank.
Good: Corrosion is never an issue with fiberglass septic tanks.
If you install a steel septic tank, corrosion is a big concern. If you go with a concrete septic tank, you still have to worry about the material breaking down with age. However, fiberglass is not prone to corrosion, erosion, or rust. The likelihood of seeing a fiberglass septic tank leak due to age is slim.
Bad: Fiberglass septic tanks may break down faster and see their lifespan compromised if the ground where you live is highly acidic.
Bonus: Fiberglass tanks are easy to patch with a fiberglass repair kit if they do develop a leak.
