If you live in an area with lots of rain it is imp to understand how septic system heavy rainfall can cause problems. Heavy rainwater can seriously affect your septic system’s function and lead to the costly repairs. In this blog, we will explain how heavy rainfall affects your septic system, what problems it causes and how to protect your system during the wet weather.

What is a Septic System?

A septic system is a home wastewater treatment system used when there is no connection to city sewer lines. Wastewater from your home flows into an underground septic tank. The tank separates the solids and liquids. The liquids then drain safely into the soil through a drain field.

How Does Heavy Rainfall Affect A Septic System?

Heavy rain can cause water from rain to enter the area close to your septic system. Having extra water in the soil brings several problems.

1. Flooding Of the Septic Tank

Septic systems may have their water table around the tank prompted to rise after heavy rainfall. If the ground becomes soaked, the septic tank can hold groundwater. This stops the tank from working properly because solids mix with liquids and may clog the drain field.

2. Saturated Drain Field

The drain field serves to take wastewater into the ground or soil. But when it rains heavily, the soil holds all the water it can, stopping more from sinking in. The result is that wastewater flows into your house or out to your lawn.

3. Soil Erosion and Damage

Wet weather can strip away the soil that hides your septic pipes or can badly affect the drain field. Leakage can occur and the system may run less efficiently because of this.

Common Problems From Septic System Rainfall

Flooding and health problems are two main results of septic tanks being affected by heavy rainfall.

• Slow or blocked drains due to a waterlogged drain field
• A backup of sewage inside your house
• Smelly air emanating from around the septic tank or drain field
• If your yard is wet, soggy or flooded around the drain field, it’s a bad sign.

Any of these symptoms seen after heavy rain mean you should have your septic system examined right away. Learn more about septic system warning signs and when to call a professional.

How To Protect Your Septic System From Heavy Rainfall

There are tips you can follow to stop issues caused by septic tanks during heavy rain.

1. Regular Maintenance and Pumping

Regular checks and cleanings of your septic tank prevent waste from backing up during heavy rains. Solids are removed during pumping because they become a problem when water levels rise. Learn more about septic system maintenance signs and when to call a professional.

2. Manage Surface Water Drainage

Move rain away from the location of your septic system. Guide all water flows from your yard’s downspouts and gutters so they do not end up at your septic tank and drain field. French drains can be set up to ensure water is diverted away from your home. For better water management, consider installing French drains around your property.

3. Avoid Heavy Loads on The Drain Field

Never drive or park anything over the drain field area. Compacted soil will stop much of the water from getting in and put your system at risk in heavy rains.

4. Plant Grass, Not Trees

Grass catches rain and keeps soil from running off. Keep trees from growing near the drain field to stop their roots from messing with the system’s pipes.

5. Reduce Water Use During Rainstorms

Water your plants as little as possible when it rains heavily. Avoid running your washing machine, dishwasher and spend as little time showering as possible to protect your septic system.

What to Do if Your Septic System Is Affected By Heavy Rainfall

If you find your septic system is flooding or has a blockage after a storm:

• Stop using water until the system is checked
• If your tank requires pumping, hire a professional to look at and clean it out.
• Repair the damaged pipes or drainage issues as soon as possible

Ignoring these signs can cause the serious damage and health risks. Get immediate emergency septic service to prevent health risks and costly damage.

Final Thoughts

Understanding how septic system heavy rainfall affects your home’s septic system is key to preventing the damage and the costly repairs. Heavy rain can flood your septic tank and drain field, causing backups, odors and yard flooding. But with proper maintenance, water management and careful use during wet weather you can keep your septic system running smoothly.

Pay attention, organize regular checks and keep water flowing away from your house to avoid damaging your septic system in the heavy rain. That way your home and the septic system are safe and healthy—even in heavy rain.
