5 Signs You Need a New Septic System (And Why Installation by Thor Construction Matters)

At Thor Construction, we understand that your septic system isn’t something you think about often—until there’s a problem. When it fails, the situation can quickly escalate from a small issue to a major mess. Whether you’re in Kawartha, Collingwood, or surrounding areas, recognizing early signs of septic system failure can save you thousands in repairs and protect your property.

Here are five warning signs that you may need a new septic system—and why homeowners across Ontario trust Thor Construction for expert installation and long-term peace of mind.

Slow Drains and Gurgling Sounds

If your sinks, tubs, or toilets are draining slowly—or if you hear strange gurgling noises—it’s likely more than a simple clog. These are early signs that your septic system is struggling to process wastewater properly.

Why it matters: Ignoring this can lead to backups, pipe damage, and a compromised septic tank. Our experienced team at Thor Construction can assess your system and recommend the best course of action before the issue worsens.

Sewage Backups or Foul Odours

Seeing raw sewage back up into your toilet or smelling strong odours in your yard is more than a nuisance—it’s a health hazard. These signs often indicate your septic system is either overloaded or has reached the end of its lifespan.

Our solution: We provide full system replacements that meet all local regulations and protect your home’s environment. Thor Construction will handle everything, from tank removal to new installation.

Standing Water Around the Drain Field

If your drain field is soggy or has standing water, especially in dry weather, your system may not be dispersing wastewater effectively. The soil may be clogged, or your system could be failing.

Why call us: A saturated drain field requires expert diagnosis and likely replacement. Our team specializes in septic system installations that work with your property’s unique layout and soil conditions.

Unusually Lush Grass Over the Tank Area

Bright green, fast-growing grass above your septic tank or drain field might look nice, but it’s often a red flag. It suggests excess waste is leaking into the soil and acting like fertilizer.

What Thor Construction does: We inspect your current system, identify leaks or overflows, and design a replacement that prevents future damage.

System Age: 25+ Years Old

Even with good maintenance, most septic systems are only built to last 20–30 years. If yours is nearing or past this age, it’s wise to plan a replacement before you experience failure.

How we help: At Thor Construction, we replace aging systems with high-quality, code-compliant installations that last decades and require less maintenance.
