Storm Drain Cleaning: Importance, Methods & Maintenance
Storm drain cleaning is the process of removing debris, sediment, leaves, trash, and buildup from stormwater drainage systems to prevent flooding and blockages. Proper maintenance ensures that storm drains function efficiently, reducing the risk of water damage, erosion, and environmental contamination.
Why Storm Drain Cleaning Is Important
✔ Prevents Flooding – Clogged storm drains can lead to street and property flooding.
✔ Reduces Pollution – Removes harmful debris that can enter rivers and lakes.
✔ Extends Drain Lifespan – Prevents pipe corrosion, blockages, and costly repairs.
✔ Complies with Local Regulations – Many municipalities require regular storm drain maintenance.
Common Causes of Storm Drain Clogs
- Leaves, branches, and dirt buildup
- Trash, plastic, and debris from streets
- Oil, grease, and chemical waste runoff
- Heavy rainfall and sediment accumulation
- Tree roots infiltrating drainage pipes
Storm Drain Cleaning Methods
Manual Cleaning (For Surface-Level Debris)
- Removes leaves, trash, and sediment using rakes, shovels, or vacuums.
- Suitable for small residential or commercial storm drains.
Hydrojetting (High-Pressure Water Jetting)
- Uses high-pressure water to blast away sediment, grease, and debris inside pipes.
- Effective for clearing blockages in underground stormwater pipes.
Vacuum Truck Cleaning (Vactor Trucks)
- Large industrial vacuum trucks suction out sludge, debris, and sediment.
- Common for municipal and commercial storm drain maintenance.
CCTV Camera Inspection (For Deep Blockages & Pipe Damage)
- A sewer camera is inserted into the drain to identify clogs, cracks, or root intrusion.
- Helps determine if repairs or replacements are needed.
Root Cutting & Removal (For Tree Root Intrusion)
- Mechanical root cutting or hydrojetting removes invasive roots.
- Prevents long-term damage to stormwater drainage pipes.
How Often Should Storm Drains Be Cleaned?
- Residential Properties: Annually or after heavy storms
- Commercial Properties: Every 6-12 months
- Municipal & Public Drains: Quarterly or after major rain events
