Aerobic septic systems, also known as aerobic treatment systems which employ natural means to treat wastewater. It uses an oxygen-rich environment to break down sewage inside the aerobic treatment unit. How does an aerobic septic system work exactly?

 

It involves four treatment processes. The first process is called the pre-treatment, a designed chamber that separates the liquid wastes from the solid ones. The second process is called the aeration chamber. Under this, the wastewater is supplied with air either by an air compressor or a blower. The air aids the growth of bacteria inside the chamber, leading to the digestion of the wastewater. 

 

The third process includes disinfection, which uses chlorine or ultraviolet light to treat the effluent discharged by the aerobic treatment unit. The last method is called the final treatment disposal, where the effluent is released into the drain field. A drain field can be an evapotranspiration bed, sand filter, or absorption field. 

 

So, why exactly are we discussing the treatment processes? Understanding how an anaerobic system works and its different types will help you know and list the possible cost for the maintenance, installation, service, operations, and materials needed. 

 

Aside from the treatment processes, there are other factors to consider before purchasing an aerobic septic system crucial in cost determination. On average, you can spend about $10 000 to $20 000. 

 

If you are planning on installing an aerobic septic system, this article is for you. Apart from what is mentioned above, here are also some things you need to consider when it comes to aerobic system cost:

 

  1. Types of Aerobic Septic System

 

There are different types of aerobic systems that you must know of before purchasing one. Choose not only what suits your personal preference but also practical and fits the area you will be installing it. You might as well consider the budget you have in your wallet. 

 

Here are the two types of aerobic system:

 

Composting toilet aerobic septic system

Composting toilet utilizes coconut coir, sawdust, and peat moss to eliminate odor as the air is vented outward. This process helps increase micro-organism production, which is beneficial for agricultural areas. 

 

The price starts at about $1 400 depending on your location and establishment. However, if you are handy enough to build your own, your expenses can be cut down from $1 400 to $50. The cost will cover your expenses on the materials such as composting bin, bucket, particleboard, medical toilet seat grade, etc.

 

Portable aerobic system

A portable aerobic septic system is also known as a retrofit septic system. This type is commonly used to remediate failing or failed anaerobic systems by retrofitting a system equipped with aerobic features. 

 

The process is called aerobic remediation. It involves the reduction of biochemical oxygen demand and the total suspended solids from the effluent. This procedure reverses the amount of bio-mat. A bio-mat is a slimy greyish layer with a foul odor. It forms on the drain field, bottom, and sides of the septic tank and trenches.  

 

The price rates can vary depending on your location and septic tank provider. It can also depend on the quality and type of material you choose to use. 

2. Maintaining an aerobic septic system.

Maintaining an aerobic septic system can give you a boatload of expenses. If you forget to schedule a regular inspection and care, you will end up spending more money. Worse, you might even resort to replacing it entirely. However, septic installments usually come with contracts that cover the maintenance, repairs, and replacements. 

 

The cost will depend on the procedures and levels of maintenance utilized. They can start at $5 to $700. This will cover minor concerns such as on-site inspections, maintenance, repairs, chlorine disinfectant maintenance, etc. 

 

The inspection can cost between $200 and $800 per year. Moreover, this contract can take care of the major concerns such as septic disinfectant, outlet effluent filter cartridge, electricity, and septic pumping. 

 

Under maintenance, consider the materials, service cost, and equipment that need to be replaced or changed. The price also depends on the amount of time required for the maintenance operations. 

 

Furthermore, if you want to save a little extra from maintenance, make sure to keep a record. This will help you determine the specific needs of your septic system, such as the dos and don’ts.

This is also needed to run the effluent pump, which releases the sludge and wastewater to its final destination, the drain field. The cost can range from $25 to $250 depending on the electricity rates of your location. 

 

To operate, the aerobic septic system will need materials such as the chlorine tablet solution and filters. They can cost about $200 to $300 in an annual purchase.

Over time, an aerobic system or some parts can become weary, get old and fail to work efficiently. A tank is always susceptible to leaks, damage, and cracks. A regular maintenance can improve the longevity of your septic tank, but everything has an end.
