What is in your septic tank?

Your septic tank contains all the waste that is produced by your household. All of the pipes from your kitchen, bathroom, and other rooms that contain pipes all meet at one pipe that goes to the septic tank. Your septic tank contains 3 layers based on weight. The bottom layer is the heaviest and is called sludge. The top layer contains fats, oils, and proteins that float on top, this layer is called scum. The middle is made up of a liquid layer called gray water. The septic tank has a drain field to drain out the gray water. The gray water has a lot of nutrients in it which makes it good for soil, which is why the grass above the tank is more green than the rest of your lawn. Over time the top layer and the bottom layer will need to be pumped and that is when you can have a septic tank plumbing and cleaning company come out to pump your tank.

The Proper Cleaning Process

Septic tank plumbing and cleaning is required to be done periodically; this is not just your usual bathroom plumbing. The top layer and the bottom layer build up over time and once the top layer is within 6 inches of the draining pipe and the bottom layer is within 12 inches of the drainage pipe is when you should get your tank emptied to avoid the contents from getting into the draining field. Since it can be difficult to tell when your seepage gets to the correct levels for a draining, it is recommended to get your septic tank system checked every year. There are certain products that you can put into your septic tank that will prolong the need for a pumping. However; there are consequences for using chemicals on your seepage. If you don’t get your septic tank pumping when necessary, it can lead to overflow into the draining field and sometimes it could come back into the house. If this happens it can lead to damages in the house, in your yard and if the tank overflows enough it can leak into nearby bodies of water or even taint underground water.

Disposing of your Septage

When it is time for your septic tank to be pumped, there are many companies that specialize in septic tank cleaning. One of these companies comes to your house with a truck with a big tank and a pumping hose. Once the tank is pumped, the tank is empty and ready to be filled again. The company then takes the septage to a dump site to be buried underground. There are a few different uses for the septage if it is not dumped. It can be used as fertilizer to grow food and it can be treated in cesspools to be broken down into effluent. A more common use for the septage is to generate electricity because of the methane it contains.
