Can septic tanks cause flooding

If the area that surrounds the septic tank or your home experiences a flood, there are high chances that your septic system will become waterlogged. It can result from a leak developing in the lid, rising groundwater entering into the outlet or inlet, or a saturated Drain Field that is not able to drain. Every property owner should take the issues of a flooded septic system with the seriousness that it deserves.

A flooding septic system can make the sewage back up in your home depending on your septic system’s elevation in comparison to the lowest drains or toilets. You should dispose of this hazardous wastewater properly so that you are safe in case there is a flooded septic system.  If you have a flooding septic system, you need to contact the right professionals to help clear the mess. If not, you will be exposing yourself to life-threatening diseases among other health hazards.

Septic System Dangers During Flooding

With proper installation, septic tanks will not be affected by floods. However, because they are located underground, leaks that allow the penetration of floodwaters will also allow debris and silt into the system. This may damage the other components of your septic system. Flooded septic tanks can experience leakages through any openings like the tank cover, outlet or inlet pipes, and the manhole cover.

The leaks can allow silt and soil to get into the septic system hence coursing the clogging of your Drainfield.  When there is an influx of water in the septic system, it will raise a layer of floating solids and plug the outlet and inlet pipes. Water that comes from flooding drain fields can also flow back to the tank.  Combining all these issues will make your drain stop running or run very slowly. It can also prevent the toilet from working or make wastewater to back up in the home.

Remedy for Septic System Flooding

The best way forward during such instances is to reduce the water usage within your property. With a flooding septic system, you will not be able to flush your sink or toilet. It means that you need to evacuate until the rainwater recedes. Therefore, you should conserve as much water as you can during a flood. You also need to contact professionals to make sure that there is proper functioning of your system.

Don’t pump the septic tank when the high groundwater is still prevailing. If you pump under such conditions, old tanks can collapse and those that were installed recently may float on the surface. You should also not try to drive heavy machinery in the area in order to compact the soil over the Drainfield area. The saturated water will interfere with the functioning of your septic system and even lead to failure.

Once the flooding water recedes, continue conserving the use of water as much that you can. The system goes through so much stress before it can function properly after the flooding conditions. Limit the number of times you flush the toilet, reduce the number of baths and showers every day, only run the dishwasher when full, and do laundry off-site.
