Problems With Underground Septic Tanks

Septic tanks contain millions of microorganisms breaking down the wastes into a liquid organic matter. Through time, the digested wastewater ultimately flows out from the septic tank and ends up into the drain fields. In severe cases of overflow, the bacterial waste process produces some gas that escape in the plumbing vents. Not only this lead to a foul smell all over the house, it also potentially harms your health. Below is a list of problems with underground septic tanks.

Overfilled Tank

As mentioned earlier, septic tanks will eventually overflow in time. By design, the septic system is a host for a healthy microbial ecosystem that will process the seepage. However, even with a well-functioning drain field, sludge and scum layers will eventually overflow. Thus, at least once every three to five years, septic tanks of a typical household must be pumped out and emptied. Septic service professionals know where and how to dispose the wastewater.

Worn Out Tanks and Lids

Believe it or not, some septic tanks can be over 100 years old. Even septic tanks that are not that old will tend to be worn out and may have damaged lids or seals. If your septic tank is already worn out and lids are not properly sealing the tanks anymore, chances are, serious septic problems will occur. In this case, a septic service professional might suggest replacing your old septic tanks into modern ones.

Blocked Septic Tanks

Another problem with underground septic is blockage. Sometimes, the septic vents become damaged, thereby blocking the septic tank. Ventilation is crucial due to the gases being produced by organic matter present in the underground septic tank. Methane gas, when being held for a long time without proper ventilation can lead to a deadly explosion. Even without explosion, a leaking septic tank with methane gas also becomes asphyxiate and can kill any individual just seconds after inhalation. In some cases, underground septic tank also collapses. Blocked septic tanks, therefore, have life-threatening dangers and must be serviced immediately.

Changed Ground Conditions

Underground septic tanks can also be problematic when ground conditions change. When an underground septic tank is installed, a percolation test is carried out to check if the ground condition is appropriate for a septic tank. However, over the years, the ground condition might change and the drainage system installed may become saturated with groundwater. In this case, the decomposition process will not occur properly.

The ultimate problem with underground septic tanks is that problems are not so noticeable. The only way that you'll be able to avoid these problems is to implement regular maintenance. In any case that you might think that one of these problems occurs, it is best to call for septic tank repair service immediately.
