If your home does not have access to a municipal sewage system, you must rely on a septic tank. Although most septic tanks do not depend on oxygen to process your sewage, an aerobic system may be a better choice, depending on your property. Before you decide on your septic system, do some research on the advantages of this type of system.

Soil Composition

A standard septic system requires an adequate drain field. Although the solid wastes are separated and settle on the bottom of the tank, the fluids are eventually released into the soil. As a result, the composition of your backyard plays an important part in cleaning the sewage. If the soil on your property is either too rocky or full of clay, it cannot serve this purpose. As a result, you may need to invest in the aerobic system where most of the treatment takes place inside the tank and only a small drain field is needed.


Aerobic systems also have some environmental advantages. The gray water that they release into the ground is cleaner, so fewer pollutants will make it into the water table, a serious problem for both people and wildlife. Too many lakes and streams already have high levels of waste in them. Also, if you depend on well water, having an aerobic tank means you are less likely to pollute your own drinking water. Less sewage in the ground is better for everyone.


These tanks clearly offer advantages over the standard systems, so you may wonder why more people do not have them. They are more sophisticated, and, as a result, more expensive. You can have a system installed for approximately $6,000 to $15,000, while a traditional, or anaerobic, system usually costs between $3,000 and $12,000. Aerobic systems may also require slightly more maintenance because they clog more often. Also, they use electricity, so you may notice higher energy bills as a result. As with most technology, aerobic septic tanks have advantages and disadvantages.

Before you install a septic tank, consider which type will work best for you. A standard system works well if you have the space for it and the right soil type. If you do not, an aerobic system may be your only real choice. However, even if you don't have to install one, you may prefer one for the benefits it offers.
