How a Hurricane Can Affect Septic Tanks and Systems

Dec 20, 2024

While most people think about flooding, fallen trees, and power outages during a hurricane, septic tanks, and systems are other essential system that often gets overlooked.  Septic Blue of Raleigh explores how hurricanes affect septic tanks and systems and what steps you can take to protect them, such as septic pumping.

Heavy Rainfall and Flooding

Heavy rainfall and flooding are the biggest threats to septic systems during a hurricane. Septic tanks are designed to handle a specific amount of water from your household. However, when large amounts of rain soak into the ground, the soil around your septic system can become saturated. This makes it harder for wastewater to drain properly.

The tank might even float or shift out of place in extreme cases. Regular septic pumping and inspections are crucial before hurricane season to prevent such issues.

Power Outages

Many septic systems, especially those that use pumps or advanced treatment units, rely on electricity to function properly. During a hurricane, power outages are common and can last for days. It’s also a good idea to schedule septic cleaning beforehand to ensure your system is as empty as possible in case of a storm.

Soil Erosion

Hurricanes often bring strong winds and heavy rains that can cause soil erosion. When the top layer of soil is washed away, the system’s ability to function correctly can be compromised.

This problem can worsen if your septic system is located near a slope or in an area prone to runoff. In these cases, working with a septic company in Apex, NC to reinforce the area around your system can help prevent erosion.

Contamination Risks

Floodwaters are not just water—they often contain harmful bacteria, chemicals, and other pollutants. When a hurricane floods your yard, this contaminated water can seep into your septic system, causing it to malfunction or overflow.

If your septic system has been exposed to floodwaters, you’ll need a professional service to thoroughly clean and inspect the system.

Backups in the Home

A sewage backup in your home is one of the most noticeable and unpleasant problems caused by a hurricane. When a septic system is overwhelmed by too much water, it can’t handle the usual flow of waste.

Regular septic cleaning and maintenance can reduce the chances of a backup, even during heavy storms. Contact a septic company immediately if you notice any signs of trouble, like slow drains or foul odors.

Preparing Your Septic System for a Hurricane

There are several steps you can take to protect your septic system before a hurricane:

1. Schedule Regular Maintenance
   Before hurricane season begins, schedule septic pumping and cleaning to ensure your system is ready to handle extra stress. A well-maintained system is less likely to fail during a storm.
2. Inspect the System
   Have a professional septic service inspect your tank, pipes, and drain field for any signs of wear or damage. Fixing minor issues now can prevent big problems later.
3. Protect the Drain Field
   Avoid parking vehicles or placing heavy objects on the drain field. This area must stay intact to work correctly, especially during heavy rain.
4. Seal the Tank Lid
   Ensure your septic tank lid is secure and sealed to prevent floodwater from entering.
5. Plan for Power Outages
   If your system relies on electricity, invest in a generator to keep it running during a power outage.

What to Do After a Hurricane

If your home and yard have been affected by a hurricane, it’s essential to assess the condition of your septic system as soon as it’s safe to do so. Here are some steps to follow:

1. Check for Visible Damage
   Look for signs of flooding, erosion, or physical damage to your tank or drain field. Contact a septic company for a professional inspection if you notice anything unusual.
2. Avoid Using the System Immediately
   If your yard is flooded, avoid flushing toilets or using water excessively until the system has been checked. Overloading the system can make problems worse.
3. Schedule Septic Service
   Even if there are no apparent signs of damage, it’s a good idea to have your system cleaned and inspected by a professional. Flooding can cause hidden problems that might not show up right away.
