Easy Care for Storm Drains and Catch Basins in Calgary

Storm drains and catch basins may not be top of mind, but they play a critical role in protecting your commercial property from flooding and costly water damage. In simple terms, storm drains collect rainwater and meltwater, while catch basins act as the first point of entry that filters debris before water flows into the underground drainage system.

For commercial property owners and managers, proper storm drain maintenance isn’t optional, it’s essential.

What Are Storm Drains and Catch Basins?

Storm drains and catch basins work together as part of your property’s stormwater drainage system.

• Storm drains carry water away from your property through underground pipes.

• Catch basins are the grated openings you see in parking lots or near curbs that collect runoff and trap debris before it enters the system.

How They Work Together

• Water flows across surfaces like parking lots and sidewalks

• It enters the catch basin, where heavier debris settles

• Cleaner water moves into the storm drain pipes

• Water is directed away from your property into municipal systems

For commercial properties, this system helps prevent pooling water, protects foundations, and supports safe access for customers and staff.

Why Storm Drain Maintenance Matters for Calgary Businesses

In Calgary, drainage systems face unique challenges that go from heavy rainfall to rapid snowmelt and freeze-thaw cycles. Without regular maintenance, even a well-designed system can fail.

Key Reasons Maintenance Is Critical

• Prevents flooding in parking lots and entrances

• Protects foundations and building structures

• Reduces liability from slips and accidents

• Supports environmental responsibility (untreated stormwater flows to natural waterways)

• Helps avoid unexpected shutdowns or business disruptions

Routine maintenance is one of the most effective ways to avoid costly repairs and operational downtime. Proactive cleaning removes debris buildup before it becomes a major blockage.  

What Are Common Causes of Clogged Storm Drains and Catch Basins

Storm drains rarely clog overnight. In most cases, issues build up over time. Common causes of clogged storm drains and catch basins include:

• leaves, dirt, and organic debris

• garbage and litter from surrounding areas

• sand and sediment from parking lots

• grease and runoff from commercial operations

• construction debris or renovation materials

• ice buildup during winter months

In high-traffic commercial spaces like hotels, restaurants, and medical facilities, debris accumulation happens faster, which increases the risk of drainage failure.

Signs Your Storm Drains or Catch Basins Need Cleaning

Early detection can prevent serious damage, so keeping an eye on the following signs is fundamental:

• Standing water around drains or catch basins

• Slow drainage after rain or snowmelt

• Unpleasant odours near drainage areas

• Overflowing water during storms

• Debris visibly blocking the grate

• Water pooling near building entrances or foundations

If you notice these issues, your system likely needs professional cleaning.

How Often Should You Clean Storm Drains and Catch Basins?

The frequency of commercial storm drain cleaning depends on your property type, usage, and environment. Here are general guidelines:

• At least twice per year (spring and fall)

• After major storms or heavy snowfall events

• More frequently for high-traffic properties

Routine inspections and cleanings are key to keeping drainage systems functioning properly and preventing emergency issues. 

What You Can Do to Help Keep Your Catch Basins Clean

While professional commercial catch basin cleaning is always recommended, there are simple steps property managers and staff can take to reduce buildup between service visits. Keeping surface areas clear helps support proper drainage and lowers the risk of blockages.

For day-to-day upkeep, small actions can make a noticeable difference:

• Clear leaves, branches, and litter away from around the drain using a rake

• Sweep up smaller debris like dirt, gravel, and trash with a broom

• Collect and dispose of all debris properly in designated waste bins

• Check nearby areas regularly, especially after storms or high winds

These basic steps help prevent debris from entering the system, but they won’t remove buildup already inside the catch basin or underground pipes. For a complete and reliable solution, routine professional maintenance using specialized equipment remains essential for protecting your commercial property.

What Happens During Professional Catch Basin Cleaning?

Professional catch basin cleaning goes beyond surface debris removal. It’s a structured process designed to restore proper drainage and prevent future blockages in commercial systems.

• Initial Inspection & Assessment

  Technicians begin by inspecting the catch basin and surrounding system to assess its condition. This includes checking for visible blockages, measuring sediment buildup, and identifying any issues affecting water flow.
  

• Vacuum Truck Debris Removal

  Vacuum trucks are used to remove sludge, sand, and debris collected at the bottom of the basin. This step eliminates heavy buildup that can restrict flow and lead to recurring clogs.
  

• High-pressure Cleaning (Hydro Jetting)

  High-pressure water is then used to break down stubborn residue inside the system. This helps clear grease, sediment, and buildup along pipe walls, restoring proper flow capacity.
  

• Drain Line Flushing

  The system is flushed to ensure water flows freely through the pipes. This step removes any remaining debris and confirms the drainage system is functioning correctly.
  

• Optional Video Inspection

  A video inspection may be performed to check the interior of the pipes. This helps identify hidden issues like cracks, root intrusion, or deeper blockages.
