Concrete septic tanks have their advantages and disadvantages. Knowing the good and bad sides of this type of home sewage system is important if you plan to install one or troubleshoot an existing concrete tank. Also, getting the basics about septic tanks made from concrete can go a long way in preventing problems in your sewage line. Remember, to maximize the benefits of having a concrete septic tank, you need to learn how to properly maintain it.
Pros of Concrete Septic Tanks
1. Long Lasting
One of the main features that make this type of septic tank popular is its durability. Unlike other types of septic tanks, particularly the plastic variety, concrete tanks are made from a strong material that can last for decades, especially if properly maintained. Due to the heavy weight of this tank, you can be sure that it will not float or shift easily, a problem that is common with plastic or fiberglass varieties.
2. Hassle-free Permit Application
Another important benefit of using this type of septic tank is that you will not have any problem when applying for a construction permit. This type of septic tank is approved for use in most, if not all, cities and localities in the US.
3. Resistant to Damage from Heavy Machinery
As mentioned earlier, this tank is quite sturdy. You do not have to worry about damaging a concrete tank with heavy machinery while you are installing one. Furthermore, even if you bury this tank in a shallow hole, you can still be sure that most heavy equipment used in homes will not be able to easily puncture this type of tank.
4. Built to Contain Large Volumes of Wastes
If you have a big family or you are constructing a commercial establishment, a concrete tank is more preferable because it can store and contain bigger amounts of wastes.
Cons of Concrete Septic Tanks
1. Concrete can Crack Over Time
Although concrete septic tanks are strong and durable, they can be susceptible to cracking as years go on, especially if you used low quality concrete for your tank. The steel reinforcements in this type of tank are also prone to deterioration and rusting. It is also worth noting that the covers in older tanks may no longer fit properly. This can cause unbearable stench to emanate from concrete tanks that have been in use for many years. Fortunately, the quality of the new concrete tanks available in the market nowadays is much better than those built decades ago.
2. Higher Risk of Contamination
Since older concrete tanks are prone to cracking, the risk of waste water seeping out of such tanks can be high. Contamination can be prevented with proper maintenance and care of your concrete septic system.
3. More Expensive
A concrete tank is more expensive than other types of septic systems. Aside from the installation or construction, a concrete tank is also more costly to repair.
4. Involves Complicated Installation
The sheer weight of a precast concrete tank makes it harder to install. It would be impossible for one person to carry the tank and install it without using heavy equipment, such as lifts and hoists.
