It can be concerning if you notice a septic smell outside your home. There could be several reasons, such as septic leaks, broken pipes, clogging due to using toilet paper, gas buildup, and many others. 


Additionally, issues in the leach field may spread unpleasant odors to the surrounding areas, posing serious health hazards to your family, pets, and the environment.  


That’s why performing a regular or scheduled maintenance inspection is essential. A well-maintained septic system is necessary for breathing in a positive environment.

Here are some common causes of septic tank odors from outside the house, such as in the yard, garden, or other places. 


  • Clogged Drains Or Blocked Pipes:  When drain pipes get clogged with debris, smelly gases waft upward and create an unpleasant odor in the yard or outside the house. Clearing these blockages helps reduce the smells. 


  • Damaged Or Unsecured Manhole Lids:  A damaged concrete lid missing its rubber seal may allow septic smells to escape. Make sure to have a secure lid with a cover so that weather stripping can help keep the odors inside, not outside. 


  • Buildup Of Noxious Gases: Over time, toxic gasses like sewage and smelly gasses naturally build up in your septic system. If it’s not pumped after a long period. Such gases are exposed after a time, which causes odors. To prevent this, these gases require a carbon filter or regular upkeep. 


  • Faulty Ventilation: Check your ventilation system in the tank. If the plumbing vent is too small, it will not allow windows to disperse odors effectively. To prevent it, ensure that adding a carbon filter and extending the vent pipe can enhance its effectiveness and reduce the smell. 


  • Leaking Sump Pumps or Temporary Repairs: A leaking sump pump or temporary seal that hasn’t been appropriately replaced allows odors to escape. To maintain smooth functioning, perform a routine inspection.
