Wet and Soggy Grass? It Could Be a Blocked Drain – Here’s How to Find Out
If you’ve noticed wet, soggy, or even smelly patches of grass in your yard, it’s not just an eyesore—it could be a sign of a more serious plumbing issue underground. One of the most common culprits is a blocked drain, but it might also be a blocked stormwater system or even a leaking pipe.
Knowing how to tell the difference can save you from major water damage, landscaping headaches, and costly repairs. In this article, we’ll break down what causes soggy grass, how to diagnose the issue, and why calling a local licensed plumber like Get Unblocked is the smartest move.
What Causes Wet and Soggy Grass?
A perpetually soggy lawn, especially when there hasn’t been much rain, usually points to an issue below the surface. Here are the three main causes:
-
Blocked Drain (Most Common)
-
Blocked Stormwater Drain
-
Leaking Pipe (Water or Sewer)
Each has different warning signs, and the repair process varies depending on the cause.
1. Blocked Drain: The Usual Suspect
Blocked drains are one of the leading causes of soggy lawns. When your property’s drainage system is blocked—whether it’s the sewer line or an overflow pipe—water has nowhere to go. It builds up underground and starts to soak the surrounding soil, eventually reaching the surface.
Signs of a Blocked Drain:
-
Constantly soggy patch in the same area
-
Gurgling sounds in toilets or sinks
-
Bad odours from outside or indoor drains
-
Water pooling near outdoor drains or inspection points
If these signs are familiar, you’re likely dealing with a blocked drain—and it’s time to act fast.
2. Blocked Stormwater Drain: When Rain Has Nowhere to Go
A blocked stormwater drain is another common reason for soggy grass, especially after heavy rain. These drains are designed to carry rainwater away from your roof and yard, and if they’re blocked, water can back up into your garden or lawn.
Warning Signs:
-
Flooding near downpipes or gutters
-
Overflowing stormwater pits or grates
-
Wet patches that appear right after rain and linger for days
Stormwater systems are completely separate from sewer drains, so it’s crucial to call someone who understands both—like Get Unblocked, your local drain experts.
3. Leaking Pipe: Water or Sewer Leaks
If neither a blocked drain nor a stormwater issue is the cause, it could be a leaking pipe underground. Over time, older or damaged pipes can crack and slowly release water into the soil, causing saturation.
Look for:
-
A sudden increase in your water bill
-
A wet area near where your water or sewer lines run
-
Sections of unusually green grass (from nutrient-rich wastewater)
How to Find the Source of the Problem
The tricky part? All these issues can look the same on the surface. That’s why proper diagnosis is key. Here’s how to figure it out:
Step 1: Visual Inspection
Walk around your yard and note where the grass is soggy. Check near stormwater grates, downpipes, and your sewer inspection point. Look for signs like bubbling or overflow.
Step 2: Smell Test
Does the area smell like rotten eggs or sewage? That could indicate a blocked sewer drain. If there’s no smell, you may be dealing with a stormwater or freshwater leak.
Step 3: Use a Hose Test
Run a hose into your stormwater drain. If it backs up or fills slowly, there’s a blockage. Don’t do this too long though—it can make the problem worse.
Step 4: Call a Licensed Plumber
Diagnosing a blocked drain properly requires professional equipment like CCTV drain cameras and pipe locators. That’s where Get Unblocked comes in.
