How Does A Septic Tank Work?

For people who live outside the municipal sewer system, there still needs to be a way to dispose of waste water safely. The most common way to do that is to use a septic system. 

How Does a Septic System Work?

A septic system is made up of a couple of parts. The first part is the tank. The tank itself is divided into two parts. The first part of the tank is where all the waste water goes. It is full of anaerobic bacteria that eat all the solids that end up in the tank.Those solids become sludge at the bottom of the first part of the tank. The liquids eventually go into the second part of the tank. That part of the tank exists just for the liquids. As that tank fills up, the liquid goes out into the second part of the septic system, the leech field. 

The leech field is underground. The water leaves the tank and then goes out to the field for further filtration. The gravel and the soil will eventually filter the fluids enough that it can go back into the ground water. However, it will take some time to happen, so leech fields should never be placed anywhere near wells. 

How Is a Septic System Maintained?

There are several things that need to be done to a septic system to make sure that it works well. The first thing is to make sure that not too much water gets run through the system. Too much water will flood the system and cause it to work inefficiently. Sludge or solids may get out of the first part of the tank and into the second part of the tank. The tank also has to be pumped out regularly. That's because the sludge will build up enough that not enough liquid will be able to make it into the first part of the tank so that it will start to back up drains in the house. The sludge can also keep the water from moving into the second part of the tank, which can cause the entire system to back up and overflow altogether. 

Septic systems are an efficient way to deal waste water for locations that are off the sewer system. As long as they are installed correctly by companies like Honest John's Septic Service Inc and cared for properly, a good septic system should be able to last for many years before it will have to be replaced.
