5 Common Signs Your Storm Drain System Needs Repair in San Diego
Storm drain systems play an essential role in protecting your property from water damage—especially in a place like San Diego, where sudden seasonal rains can create serious flooding issues. When a storm drain begins to fail, the warning signs usually appear early, and addressing them quickly can prevent expensive structural damage.
Below are five common signs your storm drain system may need repair.
1. Water Pooling Around Your Property
If you notice water consistently pooling in your yard, driveway, or near your building after rain, it’s one of the most obvious signs of storm drain trouble.
Why water pooling happens
Blocked storm drain pipes
Debris buildup (leaves, sediment, trash)
Collapsed or broken pipes underground
Why it’s dangerous
Standing water may seem harmless, but over time it can:
Weaken your soil
Cause erosion
Damage your foundation
Increase the risk of flooding inside your home or business
If water isn’t draining properly, it’s time to have your storm drain inspected.
2. Slow Drainage After Rain
After a normal rainfall, stormwater should drain quickly. If it takes noticeably longer than usual, that means something is restricting flow.
How to identify slow drainage
Gutters or drains overflowing
Water lingering in parking lots or around landscaping
Surface drains backing up
What this means
Slow drainage often indicates:
Partial blockages
Sediment buildup
Pipe narrowing
Early-stage pipe damage
If ignored, these minor issues usually turn into complete blockages.
3. Unpleasant Odors Coming from Drains
If you smell foul or musty odors coming from outdoor drains, near your yard, or even inside the building after rain, this is a warning sign that something is wrong.
Common causes
Stagnant water trapped in the system
Sewage infiltration
Organic material buildup
Blocked or broken drainage lines
When odors get worse
After rainfall
During warm weather
When storm drains haven’t been cleaned in a while
This is usually a sign of bacterial growth or sewage leaks—both requiring professional repair.
4. Visible Cracks or Sinkholes in Your Yard
Cracks, depressions, or small sinkholes forming near pathways, lawns, or driveways can point to a serious underground issue.
Why this happens
A broken storm drain pipe leaks water into the soil
Erosion begins beneath the surface
Soil starts to collapse
Why you shouldn’t ignore it
Sinkholes can expand quickly
Concrete and paving can break or cave in
It becomes a major safety risk
If you see ground movement or cracks forming, it’s important to act immediately.
5. Frequent Backups or Overflows
Backups during heavy rain are a sign that your storm drain system is struggling to keep up—or is damaged.
What frequent backups indicate
Severe blockages
Tree root intrusion
Crushed or misaligned pipes
Structural pipe failure
When to call a professional
If backups happen more than once, it is almost always a sign of a deeper problem that needs expert attention.
When Should You Call a Storm Drain Specialist?
You should contact a professional if:
Water is pooling after rain
Drains overflow regularly
Odors appear around your property
You notice cracks or ground sinking
Storm drainage seems slower than normal
Early intervention prevents thousands of dollars in damage—and keeps your property safe during storms.
