how does a septic tank work?

How Does A Septic Tank Work?

A septic tank system is an alternative to the mains sewage system whereby the wastewater is treated underground and is able to last for many generations. They’re mostly found in rural setting where there’s a lack of centralized sewer systems due to the difficulty in installing and managing them. These type of systems make use of the perfect blend of natural resources and advanced technology to treat wastewater produced from household plumbing. These includes the kitchen drain, bathroom, laundry room and more which all runs to the septic tank. When it gets to the septic tank, the organic matter will be digested and floatable matter alongside the solids are separated.

In this article, we’re going to give you a better understanding of how a modern septic tank works. Let’s take a look!

✓ All water stemming from your household goes straight into the main drainage pipe that lead directly to the septic tank.

✓ Meanwhile, the septic tank, which is usually underground and happens to be a water tight container, retains the waste water for a period long enough to enable the solid materials sit at bottom and start to dissolve. In the process, both oil and grease will float to the top as a layer of scum.

✓ Any wastewater that’s liquid will then leaves through the drainfield out of the septic tank.

✓ The drainfield, on the other hand, is a shallow excavation that’s made of unsaturated soil. The treated water is transported via the piping onto a porous surface which enable the filtration of the wastewater into the surrounding soil. The soil, in turn, treats and disperses the wastewater.

✓ Finally, the wastewater percolates into the soil for the removal of harmful bacteria alongside other contaminants.

Septic tank systems that includes a soil absorption system or a drain field is the most affordable way that you can treat your household’s waste water.

✓ Three bedroom homes of less than 2500 square feet will require a 1000 gallon septic tank.

✓ Four bedroom homes of less than 3500 square feet will require a 1250 gallon septic tank.

how deep is a septic tank buried?

How Deep Is A Septic Tank Buried?

Septic tanks may be an unknown concept to a lot of individuals in town and cities, but to those in the rural areas where certain things are unavailable, septic tanks are a necessity. After all, modern amenities such as appropriate plumbing is something we all need to live a comfortable and conveniently lifestyle.

If you’re more particular about locating where your septic tank is built in, there are a few easy ways to find out. Firstly, you can let your sewer pipes lead you in. Generally, the tank as well as drain field are normally fitted parallel to the sewer line which extends from your home. Secondly, you can also look for visual clues to check if there’s either septic tank risers or clean out ports that is coming out from the ground. This way, you’ll able to tell right away where the septic tank system is located underground. However, if there are no visual clues then you can make some intelligent guesses. Simply take a look at your building’s piping and conditions of the property to have a good idea of where the tank is buried.
