Having your yard flood may not be much of a concern as a homeowner, but since there is a large septic tank buried in your yard, it's a reason to be more concerned. Flooding can cause a septic tank to become damaged, which is why it's important to know what can happen.
Weakened Septic Tank
A septic tank is constructed with strong concrete, which can still become damaged by exposure to flooding. If the water flooding your yard is salt water, which affects people living in areas along the coast, the salt can actually penetrate the surface of a concrete tank and cause it to become weak. The concrete also has a steel frame within it, which can rust from exposure to salt water.
If your septic tank becomes weak, this can cause a major problem. The tank can collapse while underground, causing a big mess for your plumbing system and becoming a huge safety risk.
Every drain in your home uses the septic tank, which includes sinks, toilets, showers, and appliances that use water. Solid waste will sink when it reaches the septic tank, and liquid waste will flow out and go into the soil, otherwise known as the drain field. Your drain field is responsible for filtering out the bacteria before the wastewater goes into the ground and reaches the groundwater.
When the drain field is saturated with water due to flooding, liquids will be unable to move into your septic tank's drain field. You should take steps to minimize water use until the drain field has started to dry, which means not using water unless it is necessary. Be aware that the drain field can become damaged and must be replaced in some situations, which can be quite costly.
One risk of flooding is that water will find its way into your home through the septic tank. This happens when there is so much water that wastewater has nowhere to go, so it finds a way into a home through a drain. You most likely have a drain in your basement, which will be the first one affected when wastewater starts backing up into your home.
