If you live in a rural area where there are no sewers then you know that you need a septic system. Septic systems have been pretty much the same sort of idea for decades.
The Septic Tank
When you flush a toilet or have a shower or wash vegetables in the kitchen sink the waste water goes down the drain, it then travels through a pipe outside of your home in a large holding tank that is under the ground.
This holding tank is called a septic tank; it collects the waste and waste water from your entire home. The waste water flows out the tank through another pipe into a septic bed. Today’s septic tanks have two chambers, first one fills and then the other. The solids remain in the septic tank while the waste water flows out the exhaust pipe into the septic bed.
The solids that stay in the septic tank break down over time because of the high bacteria content in the septic tank. A properly working septic tank will break down wastes and solids at a steady enough rate allowing years between the need to have it pumped out and emptied.
The septic bed
From the septic tank the waste water flows out through piping to a septic bed. A Septic bed is basically a bunch of perforated piping encased in a layer of sand. The waste water flows down the piping and gradually leaks into the sand that is surrounding the perforated piping. The sand acts as a filter cleaning the waste water. By the time the water is through the sand the organic plants usually absorb it cleaning it again for a final time.
Septic systems work on time, everything takes time to travel through the system, by the time the waste water travels through the entire system it comes ready to be re-consumed.
There are many different types and variations on the septic system model but this at the root of it is the basic one that has been around for decades.
