Heavy Rain Causing Septic Trouble? Here’s What NJ Homeowners Need to Know (And Do Now)

After weeks of heavy rain across Central New Jersey, many homeowners are suddenly dealing with problems they've never seen before, such as slow drains, standing water in the yard, strange smells, or worse.

If this sounds familiar, your septic system could be overwhelmed, and waiting it out may only worsen things.

We specialize in professional septic system installation and replacement at Long Hill Contracting. Here's what you need to know about how heavy rainfall affects your system and how we can help you protect your home before minor issues become major headaches.

Why Rain Impacts Your Septic System

Your septic system and drain field rely on dry, absorbent soil to function correctly. However, when the ground becomes saturated with rainwater, it can no longer effectively absorb wastewater. This causes water and sometimes sewage to back into your home or pool in your yard.

Even a healthy system can become stressed during extreme weather. But if your system is old, undersized, or poorly installed, problems will appear much faster.

Warning Signs to Watch For

If you've experienced any of the following after the recent storms, it's time to take action:

  • Slow drains or toilets that struggle to flush
  • Gurgling sounds in your pipes or sinks
  • Sewage smells near your tank or in your yard
  • Standing water or soggy patches near your drain field
  • Water pooling above the septic tank

These are signs that your septic system may be failing or oversaturated, and continued water use could worsen things.

What You Should (and Shouldn't) Do Right Now

If your septic system seems affected by the rain, follow these steps to prevent further damage:

DO:

  • Call a licensed septic professional immediately
  • Limit your water use as much as possible (showers, laundry, dishwasher, etc.)
  • Keep people, pets, and vehicles off soggy areas near the tank or drain field
  • Take notes or photos of symptoms for your contractor

DON'T:

  • Don't assume it will fix itself when the rain stops
  • Don't pump your tank without inspecting it could collapse the system if the ground is too saturated
  • Don't use chemical additives or DIY treatments, they won't fix structural issues
  • Don't wait to get professional help, septic issues escalate fast
