What is a Septic Tank?
If you live on a septic system, you likely have a septic tank. Septic tanks are the first step in the treatment of wastewater. When you flush a toilet, water drains down the pipe and out of the house and into the tank. From the first time you’ve ever flushed, solids have been collecting in your septic tank. The solids settle in the tank and after a couple years, they need to be pumped out.
The purpose of a septic tank is to collect solids flushed down the drain. This prevents them from entering the soil absorption system, where they clog it up overtime and cause it to fail. Seeing solids building up in your septic tank over time is a GOOD sign. This means that your tank is trapping solids like it was designed to do. However, if you do not get the septic tank pumped every couple years, the tank will reach full capacity, and solids will start flowing into the drainfield.
It is actually when you DO NOT see solids building up in your septic tank over time that is a bad sign. This means the solids are collecting elsewhere in your system, where they are extremely harmful to your system.
So how does a septic tank collect solids?
A septic tank has septic baffles. These baffles work by trapping floating solids inside the tank, so that it may not enter the drainfield area, where it can cause major problems.
