Ground Flooding

The drainfield purifies water and thus it is dispersed safely to the surrounding soil. The septic tank can hold a certain level of wastewater. However, significant rainfall can flood the surface around the drainfield.

The excess water gets mixed with the wastewater and overwhelms the tank. If the water does not find any way to go, it will come out and make a pool in the yard. Also, it may go back into drains and flood your home.

Clogged Drainfield

It is another potential problem related to the plumbing system. During the rainfall, the drainfield becomes saturated. Therefore, it won’t be able to absorb wastewater. As the water has nowhere to go, it will overflow the septic tank. Over time, it will cause plumbing issues such as foul odors and gurgling pipes.

Clogged drainfield also facilitates the flow of untreated sewage to the groundwater. As a result, it can mix with local streams leading to serious contamination.
