In Upstate South Carolina, we’re no stranger to extreme weather conditions and heavy rains. Whether it’s the ice storm that just hit us a few weeks ago or Hurricane Helene which is still painfully fresh in many of our memories. Thankfully the latest storms were not as extreme as was predicted, but that may still leave you wondering… can these heavy rains affect my septic system? The simple answer? Yes. But let’s dive in a little deeper below!
What Happens When Your Yard Floods
If your yard gets soaked after heavy rain, your septic system might stop working for a while. Flooded drainfields can’t treat wastewater properly, so you should wait to use your plumbing until the water level drops below the septic tank and drainfield. Using your plumbing too soon can cause backups and contamination.
Heavy rain can soak the ground around your drainfield and make it hard for the system to filter and spread out wastewater. Septic tanks are designed to handle only your household’s wastewater, not extra rainwater. If rainwater gets into the tank or drainfield, it can overload the system and cause backups, slow drains, or even wastewater surfacing in your yard.
Clogs and Contamination Risks
Even though septic tanks are buried underground, floods can still let in dirt, silt, and debris. Yard waste, storm runoff, and cleanup materials might get into the system, raising the risk of clogs and contamination. To help prevent this, keep the area around your system clear during storms and clean up soon after.
Protecting Your Septic System During Cleanup
Cleaning up after a storm can sometimes harm your septic system by accident. Driving heavy vehicles or equipment over wet ground can damage drainfields, tanks, or distribution boxes. Avoid driving over your septic system after heavy rain. If you notice signs of trouble like bad smells, wet spots, or slow drains, call a licensed professional for an inspection and repairs. Sometimes, you may also need to let your local health department know.
Additional Things To Keep an Eye On
• Rainwater from roofs, driveways, and packed soil can flow toward your drainfield and make it even wetter. Point downspouts and surface water away from your septic area to help keep it dry.
• Tree roots can get into septic lines, especially when the ground is loose or soaked. Check your system for signs of root problems after storms.
• Regular septic maintenance, like pumping every 3 to 5 years, can help prevent your system from getting overloaded during bad weather.
