What Happens to Your Septic System in a Flood

• Contamination Risks

Floodwaters can carry contaminants such as oil, gasoline, bacteria, and raw sewage. If your septic system is compromised during a flood, these contaminants can enter the groundwater or surrounding areas, posing a serious health risk to your family and neighbors.

• System Overload

Excess rainwater entering the septic tank from leaks, broken seals, or improperly connected gutters can cause the tank to overflow. This may lead to untreated sewage spilling into your yard or nearby bodies of water.

What To Do Before a Flood

Preparation is the best defense. If you live in an area prone to heavy rains or flooding, take proactive steps to safeguard your septic system.

• Schedule Regular Septic Tank Pumping: A full tank is more vulnerable during a flood. Routine septic tank pumping in Atlanta, GA reduces the risk of overflow and back-up.
• Inspect and Maintain Your System: Have your system checked annually for cracks, leaks, or signs of failure. Proper maintenance includes regular septic tank cleaning and monitoring of the drain field.
• Install Backflow Preventers: These valves can help prevent sewage from re-entering your home through drains.
• Avoid Heavy Equipment Near the Tank: Before a flood, avoid driving over or placing heavy objects near the septic system, as saturated soil can easily collapse.

What To Do After a Flood

Once floodwaters recede, it’s important to assess the condition of your septic system immediately.

• Don’t Use the System Right Away: Even if things seem dry, the soil may still be saturated, which can prevent proper drainage. Wait until the ground has dried out before resuming normal use.
• Schedule a Professional Inspection: Have a licensed septic professional inspect the tank and drain field. You may need septic tank pumping or even a full septic tank cleaning to remove any debris or sludge that entered during the flood.
• Check for Structural Damage: If the tank has floated or shifted, it may require repair or a new septic tank installation.
• Avoid Well Contamination: If you have a private well, have the water tested to ensure that floodwaters didn’t contaminate your drinking supply.

Protecting Your Septic System Long-Term

Flooding is unpredictable, but a well-maintained system is your best protection.
