Call Now
It’s the middle of a New Jersey summer. The heat is relentless, the lawn’s drying out, and suddenly… your septic system starts acting up. Maybe it’s a foul odor in the yard. Maybe your sink is draining slower than usual. Either way, it’s not a coincidence.
Heatwaves can affect your septic system, especially in areas like Sussex County and North Jersey where sudden droughts and high usage are common. When temperatures soar, the components of your system are put under stress—and if you’re not prepared, that stress can turn into a much bigger issue.
Here’s what to look for, how to reduce the risk, and why Wilson Services is the team to call if things start going south.
Yes, Heatwaves Can Affect Your Septic System. Here’s How.
Increased Household Water Usage
When it’s hot, water usage goes up. That might include:
- Lawn irrigation
- Pool filling or topping off
- Extra laundry and showers if you’re hosting visitors or just trying to cool off
All of that adds more liquid to your system—sometimes more than your drain field can comfortably handle. Over time, that added strain can lead to backups or odors.
Dried Out or Cracked Soil in the Drain-Field
High heat pulls moisture from the soil, including the area around your drain field. When that soil becomes dry or compacted, wastewater can’t be absorbed properly. In extreme cases, it may even cause surface pooling or localized sewage smells.
If you notice parts of your lawn drying out or becoming oddly lush above the drain field, that’s worth paying attention to.
Evaporation and Bacterial Imbalance
Inside your tank, bacterial ecosystems do most of the work breaking down solids. But those bacteria are sensitive to temperature. During heatwaves, the balance can shift, which slows the decomposition process and can create buildup or odor issues.
Heat also increases evaporation, meaning your plumbing traps and vent stacks might dry out faster than usual, allowing gases to creep back into your home.
Tree Root Intrusion Accelerated
During dry spells, tree roots go searching for moisture. Your septic system, especially if it has small leaks or cracks, can become a prime target.
Once roots break in, they can block or damage pipes, leading to long-term problems that are expensive to fix. If you have trees or shrubs near your system, summer is when they’re most likely to start creeping in.
Wilson Services offers septic inspections that can catch this kind of damage early.
Signs Your Septic System Is Struggling in a Heatwave
Some common symptoms of a stressed-out system include:
- Sinks or tubs that drain slowly
- Gurgling sounds from toilets or drains
- Odors in the yard or inside your home
- Patches of grass that are unusually green or dry above the drain field
- Standing water in your yard even though it hasn’t rained
If you notice any of these signs, it’s a good idea to schedule a checkup. Wilson Services can help you get to the root of the issue.
What NJ Homeowners Can Do During Extreme Heat
Smart Water Management
- Spread out water-heavy tasks throughout the day
- Fix leaks in faucets or toilets to avoid wasting water
- Make sure sprinklers aren’t soaking your drain field
Reducing the daily water load helps your system process wastewater more efficiently.
Yard and Drain-Field Care
- Don’t drive or park over the drain field
- Avoid saturating the grass above septic components
- Trim roots and monitor trees growing near the system
What happens above ground can impact your septic health just as much as what’s happening underground.
Regular Maintenance Is Crucial
Prevention is key. Book regular pumping and maintenance to avoid problems before they start.
- Schedule septic pumping before peak summer use
- Book a septic inspection to check for signs of strain
- Explore septic maintenance plans that include vent upgrades and system monitoring
Already dealing with an issue? Emergency septic pumping is available if things can’t wait.
