What is a Septic Tank System?

If you live in a city or town you probably take your local municipal sewer system for granted. If you are moving out of said city or town to a more rural setting chances are you will need to have a septic tank system. In simple terms this means that all your waste water and sewage waste is treated right on your property instead of flowing down to the local waste water treatment plant. While this may not sound very sanitary there is nothing to worry about because septic tanks have been in use for many years. In fact nearly 25% of all homes in the U.S. use septic tank systems.

A septic tank system is a very simple structure, but for all its simplicity it is very efficient at what it does. The tank itself can be anywhere from one thousand gallons or higher and is usually placed a good distance away from the house. The main sewer pipe from the house is attached to one end of the septic tank while another pipe exits the far side and is buried in what is called the leech field.

The liquid and solid waste enters the first chamber in septic tank through the pipe connected to your house. The solids are trapped in this first chamber and are broken down by anaerobic bacteria. This reduces the amount of solid waste in the septic system allowing the liquid wastes to flow into the second chamber which then flows out the end pipe and into the leech or septic field. In most cases this is all accomplished with the help of gravity as we all know that poop flow downhill. In some cases the septic tank cannot be placed downhill from the house so a pump will need to be used in order for the system to work properly.

The liquid waste that flows into the leech field is relatively benign and will create a nutrient rich growing area. Any plants growing over it will thrive and many septic fields can be located just by finding the patch of land that is greener then the surrounding area.

As efficient as a septic tank system is there will always be solid waste that is not fully decomposed. This will eventually fill up the septic tank and require that you contact a septic tank cleaning service to pump out your system. Worst case would be to have this done every year but most systems can go up to two years before needing to be cleaned out. Properly taken care of a septic tank system will do its job efficiently with few problems to worry about.
