What’s Clogging Up the Works?

Stormwater drains are pretty good at doing their job, taking the runoff from impervious surfaces and directing them to systems that can clean the water and regulate deposits into local waterways.

Block Storm Drain - Organic DebrisHowever, these drains can occasionally become blocked, backing up water in places where it shouldn’t be. Here are the usual suspects:

  • Natural Debris: Leaves, grass clippings, and natural sediment love to gather in your drains, blocking water flow. This is especially true in leafy areas or during fall.
  • Non-Biodegradable Waste: Tossing non-biodegradable stuff like plastic bags, bottles, and even grease down the drain can lead to serious clogs. These items can build up and cause blockages that are hard to remove.
  • Roots: Tree roots have a knack for infiltrating drainage systems. They grow and expand, destroying the stormwater system and causing significant blockages.
  • Heavy Precipitation: Heavy rainfall can overwhelm your drainage system, leading to immediate clogs. Sudden downpours can wash debris into drains faster than they can handle, causing blockages.

How to Know if Your Stormwater Drain Is Blocked

Spotting a blocked stormwater drain early can save you from serious trouble. It’s important to take a quick look at your storm drain before and directly after a major rainfall event.

However, if after a minor or major rainfall event, you see these warning signs, it’s time to investigate the issue.

  • Pooling Water: If you see water pooling around drains or in parking lots after a rain event, it’s a clear sign something’s up.
  • Slow Drainage: Water that takes its sweet time to drain is usually a sign of a partial blockage and it’s a good time to ensure it’s not a part of a more serious issue.
  • Nasty Odors: Foul smells coming from your drains often indicate trapped, decomposing debris.
  • Overflowing Gutters: Gutters and downspouts overflowing during a rainstorm mean the water isn’t flowing freely through the system.

The Hazards of Avoiding The Warnings Signs of a Block Stormwater Drain

Ignoring blocked stormwater drains can lead to a cascade of issues:

Excess water can cause flooding, damaging your property and infrastructure. Floodwater can seep into buildings, ruining interiors and electrical systems.

Building occupants don’t want to have to tread through standing stormwater on their way in and out of a building. While is inconvenience may not seem serious, property/facility managers know that this issue can change how people feel about the property management of their workplace, home, or other places they frequent.

Blocked drains can worsen erosion, undermining foundations and landscapes. This can lead to expensive structural repairs, sinkholes, and lost landscaping among other things.

Health Hazards
Standing water attracts pests and breeds mold, posing serious health risks. Mosquitoes, for example, thrive in stagnant water, bringing potential diseases.

Legal Trouble
Failing to comply with local stormwater regulations can land you with fines and penalties. Municipalities have strict guidelines to prevent environmental damage from poor stormwater management.

Incredible stormwater management service. The owner John consulted on a property I manage and ended up saving us thousands of dollars in environmental fees from the government.
