Septic Tank Installation

I grew up in a house that had a septic tank, and I was always surprised at how many of my friends had no idea what this type of sewage system even was. For people who have always lived in areas with public sewage systems, septic tanks can be a bit of mystery. In reality they're quite simple and they're the only solution for people who live out of reach of the public pipes.

What is a Septic Tank?

Septic tanks are basically individual systems used for treating and disposing of the sewage waste from a single house. They are installed in the ground, and they process all of the sewage exiting the house. Septic tanks convert your sewage into three byproducts: gas, sludge, and liquid waste.

Getting rid of sewage is obviously a problem, and septic tanks do it in three different ways. The gases that are separated from the sewage are usually released into the air, since they are non-toxic (but usually quite smelly, which is why the pipes are often at the top of your house). The liquid waste (also non-toxic and relatively safe for the environment) is absorbed into the ground at the base of the septic tank. The sludge is the most dangerous byproduct, and this has to be professionally removed from the septic tank every few years.

It would be nice if septic tanks could last as long as your house, but in most situations this simply isn't the case. Many old houses have septic tanks that need to be replaced, and this is something that people often do when they sell the house (in many areas it is actually required by law). The good thing is that modern septic tanks are far more durable than those built in the old days, so if you're installing a new septic tank you probably won't have to worry about it for a long time to come.
