Many houses in the United States have septic tanks that hold the contents of waste and water that is pumped from the house. Generally, these tanks need little maintenance, but if you fail to do even the simplest maintenance, it could become an expensive problem. Here are some things you need to know about your septic tank.
What Is a Septic Tank?
A septic tank is a tank that lies below the ground. It usually has a single pipe that leads to the tank and this single pipe takes all of the water, waste, and any sewage that comes from the house. Then once it gets to the tank. It separates. The lighter contents float to the top, and the heavier contents soak to the bottom. Then as the tank is drained the things that can be used as fertilizer are used as so, and the other is kept in the tank. The contents that are safe to drain will drain into a drain field. This is a place that can safely take all of the water and fertilizer that is discharged from the tank.
What Happens to the Contents of the Tank That Can't Drain?
The heaviest layer is called the scum layer. This layer will naturally build up over time, and it won't be able to be drained into the field. It will need to be emptied manually by a septic tank cleaning company. Usually there is a certain level the scum can get to before it needs to be drained. You won't know when it is a problem until it is too later. For instance, if it starts backing up into your bathtub, you have waited much too long. This is why it is recommended that you have the tank checked annually. The cleaning company will be able to measure the level of the scum to see if it is getting to high and if it needs to be drained.
After the company has removed all of the scum from the tank, they will take the sewage and put it in an area that has been designated for such waste. These areas are usually off limits and kept far away from people. However, there have been inventions that have made it so that the sewage can be used for more environmentally friendly options, such as helping to power electrical pants.
