Commercial Property Services
Catch basins are the unsung heroes of commercial property drainage — they quietly collect surface runoff and direct it to the municipal storm system. When they fail (or are ignored), the results range from minor flooding to significant pavement and property damage.
Catch basins require annual cleaning as a minimum standard for most commercial properties. High-traffic lots with significant vehicle-deposited silt, properties near construction zones, or lots with significant tree cover may need semi-annual cleaning.
Industry Best Practices
What accumulates in catch basins: sand and silt deposited by vehicles and runoff, litter and debris, leaves and organic material, and in some cases, oil and fuel contamination. This accumulation restricts flow capacity and, if deep enough, can back up into the inlet structure.
Signs a catch basin needs cleaning: water pools near the basin inlet after moderate rain (when it previously drained quickly), visible debris or silt above the water line in the basin sump, slow drainage across the lot during or after rain events.
How D&D Commercial Services Can Help
Catch basin inspection beyond cleaning: check the structural condition of the basin walls and frame. Cracked concrete walls, deteriorating mortar joints, and settled or damaged frames all require repair. A collapsed catch basin is a serious safety hazard.
Catch basin grates: the grates that cover catch basin inlets get damaged by vehicle traffic and equipment. Damaged or missing grates create vehicle damage and trip hazards. Inspect grates annually and replace when bent, broken, or missing.
Environmental compliance: catch basin cleaning generates waste (silt, debris, contaminated water) that must be disposed of in accordance with Ontario environmental regulations. Ensure your contractor disposes of catch basin waste properly.
