How Often Should You Schedule Catch Basin Cleaning for Commercial Properties?

Commercial property managers know that drainage maintenance matters — but how often is often enough? The answer depends on your property type, traffic volume, and surrounding environment.

General Guidelines

For most commercial properties in the GTA, we recommend bi-annual cleaning: once in early spring (after snowmelt) and once in late fall (before freeze). This schedule addresses the two heaviest debris periods of the year.

Properties That Need More Frequent Service

• High-traffic parking lots (shopping plazas, malls, grocery stores) — quarterly
• Properties near mature trees — quarterly during leaf season, bi-annual otherwise
• Auto dealerships and repair shops — quarterly due to oil and chemical runoff
• Construction-adjacent properties — monthly during active construction
• Food service properties — quarterly due to grease and organic waste
• Industrial facilities — quarterly or as dictated by environmental permits

The Cost of Under-Maintaining

Emergency callouts cost significantly more than scheduled maintenance. A single flooding event can damage inventory, vehicles, and building foundations — not to mention liability exposure from slip-and-fall incidents on flooded walkways. Proactive maintenance also extends the lifespan of your drainage infrastructure.

Maintenance Plans

We offer annual maintenance contracts with scheduled visits, priority emergency response, and discounted rates for multi-property accounts. It is the most cost-effective way to keep your drainage system healthy year-round.
