5 Symptoms of Broken and Failing Septic Tanks

Maintaining a well-functioning septic system is not just a responsibility but a necessity to ensure the safety of your property and the surrounding environment. Septic systems handle waste in a way that prevents contamination and protects water sources, but when they fail, the consequences can extend beyond your property. Recognising the early signs of septic system issues is crucial to preventing costly repairs, avoiding serious health risks and mitigating environmental damage. Here are five signs to watch for that signal your septic system needs immediate attention.

One of the most noticeable signs of a failing septic tank is the presence of unpleasant odours around your property. If you detect a strong, foul smell, especially near the drain field or the tank itself, it could indicate a problem with your septic system.

These odours are often a sign that sewage is seeping out, releasing harmful gases that smell bad and can pose health risks if inhaled over prolonged periods. The presence of these gases typically suggests that the septic tank is overloaded or that there is a blockage preventing proper waste treatment.

If you notice that sinks, toilets or showers are draining more slowly than usual, it might be a sign of a blockage or a failing septic tank. This issue can result from a full septic tank, clogged pipes or problems with the drain field, such as soil compaction or root intrusion.

When wastewater cannot flow smoothly from your property to the septic tank, it causes slow drainage. This can lead to backups, where wastewater returns to the plumbing fixtures. These backups can cause damage to your property and pose health risks due to exposure to untreated sewage.

While a green lawn might seem like a sign of healthy grass, it can sometimes indicate a failing septic system. If you notice that certain areas of your yard are significantly greener and more vibrant than others, it could be due to leaking sewage from your septic tank. The wastewater acts as a fertiliser, causing the grass in the affected area to grow more quickly and appear greener than the surrounding lawn.

This is a clear indication that untreated waste is seeping into your yard. This leakage usually occurs because of cracks in the septic tank or issues with the drain field, such as clogging or improper soil absorption. These leaks can lead to significant environmental contamination, affecting your yard and potentially nearby water sources.

Pooling water or damp spots in your yard, especially around the septic tank or drain field, is an indicator of septic system failure. These wet areas can emerge even during dry weather, suggesting that wastewater is not being properly absorbed or treated. This issue often arises when the drain field is overloaded or the septic tank is leaking, preventing wastewater from being effectively processed and absorbed into the soil.

When a septic tank overflows, it releases untreated or partially treated sewage into the surrounding area. This creates unsanitary conditions and can also lead to soil erosion and further system failure.

Gurgling sounds typically suggest that air is trapped in the pipes due to a blockage or improper drainage. This trapped air can create pressure differences in the plumbing system, leading to unusual sounds.

The gurgling is often more noticeable in fixtures like sinks, toilets and bathtubs. If these noises persist, it suggests that there is a significant issue within the septic system that needs to be addressed.
