Comparing Aerobic vs. Anaerobic Septic System Costs

August 17, 2021 8:28 pm Published by Writing Staff

If you own a home in a small town or a rural area, chances are you’re familiar with the concept of a septic tank. A septic tank system treats all the wastewater you use in your home and eventually returns the water to the ground after harmful chemicals are filtered out of it.
If you know the difference between aerobic and anaerobic exercise, then you’re close to understanding the differences between an aerobic septic system and an anaerobic septic system.
In an anaerobic system, oxygen is not used to treat the wastewater. Oxygen, is used to purify the septic system’s wastewater. Here’s how the two systems stack up when it comes to costs.
Anaerobic septic systems
These types of septic systems are more common and simpler than aerobic septic systems. They also require fewer components than aerobic septic systems because there’s no need for aeration of the bacteria.
There are several factors that will affect the cost of your anaerobic septic system, including location, the size of the tank and the condition of the soil. Here are some rough numbers outlining how much anaerobic septic systems cost:
Permit: $250 to $1,000: You’ll need to secure a permit before you start building your septic system, and the price will vary by area.
System: Start around $7500.00: This is the price of the system as a whole, and includes labor. Though they’re significantly cheaper than aerobic septic systems, your price will depend on the Engineer’s design and the size of the system.
Aerobic septic systems
Aerobic septic systems are expensive. Here are some rough cost outlines for aerobic septic systems:
Permit: $200 to $400: You’ll need to have the site of your future septic tank evaluated, in addition to securing a permit.
System: $10,000 to $20,000: As you can see, the total average cost of an anaerobic septic system is significantly more than that of an aerobic septic system.
Motor replacements: $500 to $600: An aerobic septic system uses a motor, and you’ll likely have to replace it at some point.
Timer replacement: $100: You’ll also have to eventually replace the timer on your aerobic septic system.

Labor costs
Regardless of which type of septic system you choose, the cost to install it will likely run you between $7500 and $15000. This is something to keep in mind when comparing quotes from different companies.
