If you already have a septic problem, there are several possible scenarios. First of all, it is possible that your septic system can't be fixed, due to a design flaw (i.e. the water table is too high) and/or lack of maintenance. However, in many cases they can. First of all, learn about how to use septic systems properly, and immediately cut back on any practices that may be damaging your system- such as overuse of water. In quite a few cases, a tune-up can fix your system and you can avoid the high costs of replacing the system. This tuneup includes properly pumping the tank, cleaning (jetting) the drainfield lines, and installing washing machine and effluent filters. If these measures are not sufficient, some failed systems can be rejuvenated by fracturing the soil. This process utilizes a hollow tube inserted into the soil, then a 300 pound blast or air is injected into the soil creating thousands of tiny fissures. These fissures allow the drainfield to drain, creating an oxygen atmosphere and the aerobic bacterial colonies to repopulate. Aerobic bacteria, which require oxygen, typically live in the top 26 inches of the drainfield and process waste much more quickly than anaerobic bacteria. This process can be performed in a matter of hours with no digging or damage to the yard.

Septic system failure is actually pretty easy to understand. When a system fails, the tank itself doesn't fail- the drainfield soil fails. In most cases the soil fails when it gets plugged up with solids and won't allow liquid to pass through it. For example, it can get plugged with solids from the tank if the tank hasn't been pumped, or with lint from a washing machine.
