You need to know the size of your house before answering the question: how much do septic tanks cost? For sure, a bigger house will require larger septic tanks. Bigger house has more toilets, sinks, and other wastewater sources. All of this will flow down and end in the septic tank.

You can count how many bedrooms you have to predict the size of a septic tank. Commonly, each bedroom requires a 500-gallon tank. This type costs around $720, excluding the labor cost.

Meanwhile, a five-room house needs at least a 1,500-gallon tank, which costs around $2,250.

Factor 2: The Cost of Labor

Installing a septic tank requires professional work. This is because you’ll need to come up with good water system plans. You also have to excavate and hook the plumbing pipes.

Because of this, usually, labor costs take the biggest portion of the septic tank installation. The range of the cost is $1,500 to $4,000. It all depends on the complexity of the system and how big the septic tank is.

Factor 3: Septic Tank System

If you question how much do septic tanks cost, you need to also consider what type of septic tanks you will get. Commonly, people use either an anaerobic or aerobic septic system. Here are the differences between anaerobic and aerobic systems.

For an anaerobic system, the pipe will be connected from your home to the septic tank. Meanwhile, another pipe will be installed from the tank to the leach.

An anaerobic septic tank can crush the waste with bacteria, where the bacteria do not require oxygen to live. Hence, this system is called anaerobic.

Although this system is cheaper, an anaerobic septic tank requires a large drain field. If you have a minimalist house, this system is not recommended.

Unlike the anaerobic system which costs only around $2,000 to $6,000; the aerobic system cost is tripled, from $10,000 – $18,000.

This type of septic tank is more expensive due to its complexity of installation, as it also involves moving parts. As the name states, the aerobic system applies an aeration process and oxygen-feeding bacteria to decompose the waste.

For this system, you will need a septic tank, pipes, electrical hookups, a pump tank, and an aerator. For small houses, it will be best to have this system installed since they do not require large water drainage.

Another good thing about the aerobic system is it works more efficiently with the bacteria’s assistance. Hope this article helps to answer your curiosity about how much do septic tanks cost.
