Several issues can contaminate a water supply with septic waste backflow. Homeowners concerned about this problem should understand how it happens, so they know when to schedule a well inspection. Here are some of the causes of backflow.

3 Reasons for Septic Backflow

1. Clogged Septic Filter

Septic tank filters reside inside the outlet area of the tank to prevent solid waste from entering the pipes to the leach field. These tubes move treated liquid waste to the soil, where it percolates to the surface.

Without an intact filter, the leach field outflow can clog, forcing waste inside the home, causing it to bubble up through the drains or break through the pipes and pool in the yard. These problems can be hazardous to human and pet health because sewage can carry E. Coli, salmonella, hepatitis A, and other diseases. Homeowners should contact a septic specialist to remove the filter and wash it, mitigating untreated solids like grease and fats. 

2. Tree Root Infiltration

As trees expand, their roots reach for water, and they may break through clay or concrete septic pipes to gain hydration. Broken pipes can flood the yard and drain field with sewage, potentially contaminating the underground water source.

If you have waste puddling on the property, get a well inspection immediately to ensure your water is still safe to ingest. If not, the technician can provide recommendations on how to treat the problem to make the liquid drinkable. 

Prevent tree root problems by planting trees over 50 feet from septic and water lines. Get regular pipe camera inspections to look for roots starting to break into the pipes. It’s easier to replace plumbing when there is a small leak, and you can lower the risk of waste entering the water supply.

3. Incorrect Pumping Timing

Septic tank manufacturers provide a recommended pumping and cleaning timeline based on the container size. Follow this information for your home to avoid the tank overflowing and causing backflow into the house or yard. Many systems require pumping and cleaning every three to five years, with more frequent services for homes with a lot of people and appliances that create wastewater.
