The septic system is an essential part of the residential sewage systems. These septic tanks are mostly constructed from concrete and collect wastewater and sewage from the house.

Why is it important to clean out the septic system?

One of the main reasons for cleaning out the septic tank regularly is to avoid overload. Pumping out the septic system is crucial due to the tank’s primary purpose. These septic tanks are designed in a way that heavy substances settle at the bottom, which over time, can form a slush layer. If the slush builds up and form more layers than it should, more solid substances will make their way into the soil absorption system.

As the absorption system pipes become clogged, it prevents liquids from flowing through and out of the pipes to be absorbed into the nearby soil. In the end, the unsanitary water will make its way back to the surface since the septic system is overloaded. But how will you know that it is time to clean out the sewage system?
