Excessive rain can mean trouble!

Flooded Backyard

It’s Raining…It’s Pouring… What does that mean for your home’s health and longevity?

Excessive rain, which we often see in the springtime, can affect different areas and systems within our homes. Most homeowners don’t like to think about their septic system too often, but it is one of the most important parts of your home – especially when it is not functioning properly.

Risks to your septic system

Heavy rain can oversaturate the soil around your septic tank and cause flooding which can lead to serious and potentially disastrous results. When rainwater infiltrates the system, causing the tank to take in more liquid than it can handle, water cannot flow out of the septic system properly. With nowhere else to go, water can flow out of the septic tank and pool in your yard. Worse yet, it can back up into the drains and toilets of your home.

Minimize flooding risks before heavy rains

Regular maintenance of your septic system and proper prevention can minimize your risk of flooding from heavy rain and help prevent backup.


  • Be mindful of what goes down the drain. Only flush septic safe, biodegradable material.
  • Direct gutters and any runoff water so that it moves away from your drain field.
  • Conserve water during rainstorms by avoiding heavy water use, such as long showers, baths and laundry.
  • Keep up with regular maintenance of the septic system to ensure it is working efficiently throughout the year. 
  • Do not drive heavy equipment or other vehicles over the drain field which could compact the soil.

What should you do if flooding occurs?

If you do experience a flooded septic system, it is important to know that pumping the tank is not the best solution, in fact, it can actually cause damage if the soil is still saturated. The best course of action is to reduce the amount of water use in your home and give the drain field time to dry. Additionally, adding any kind of chemicals or other material will only aggravate the problem. Be sure to schedule an appointment with a septic system or home damage specialist to assess any potential damage and solutions.
