Catch Basins & Storm Drains for Commercial Sites

Protect Your Property. Control Runoff. Stay Code-Compliant.

When it comes to managing surface water on commercial and municipal sites, catch basins and storm drains are essential infrastructure. Whether you’re dealing with parking lot runoff, heavy stormwater from rooftops, or roadway drainage, an engineered storm drain system protects your property and surrounding areas from costly water damage and erosion.

At Diversified Drainage, we design and install high-capacity catch basins and storm drains that perform in Minnesota’s toughest conditions—and meet today’s strict stormwater management standards. We work with property managers, developers, engineers, and contractors to deliver drainage solutions that work for the long haul.

What’s Included: Commercial Catch Basins & Storm Drain Systems

Our commercial drainage team provides full design and installation of engineered stormwater collection systems in Central Minnesota, including:
Catch Basins
Heavy-duty concrete or HDPE basins collect runoff and debris from paved surfaces and direct it safely into the stormwater system.
Surface Drain Inlets
Curb inlets, grated inlets, and trench drains that capture sheet flow and high-volume runoff in parking lots, loading zones, and drive lanes.
Storm Drain Piping
Subsurface storm drain pipes (RCP, HDPE, PVC) sized to handle expected flow volumes and site-specific hydraulic demands.
System Tie-ins & Connections
Tie new catch basins and storm drains into municipal stormwater systems or onsite retention/ detention systems for full code compliance.
Maintenance & Repair
Inspection, cleaning, and repair of existing catch basins and storm drains to ensure optimal performance and prevent failures.
Commercial Drainage Benefits

Why Proper Storm Drainage Matters for Commercial Sites

Prevent pooling, heaving, and subsurface washout that damages parking lots, slabs, and sidewalks.
Efficiently capture and route large storm events away from structures and critical areas.
Ensure your site meets local and state stormwater management requirements—including water quality standards and flow rate restrictions.
Reduce slip/fall risk and property damage caused by standing water, ice, and uncontrolled runoff.

Commercial Drainage FAQs

Proper stormwater management starts with the right system—and a clear understanding of how it works. Explore these FAQs to learn more about catch basins and storm drains.

How do I know if my site needs additional catch basins or storm drains?

If you’re seeing standing water after storms, pavement heaving, or localized flooding—your existing system may be undersized or failing. We can assess flow patterns and recommend upgrades.

Can storm drain systems be added during site renovations?

Yes. We often design retrofit systems during parking lot replacements, building expansions, or site redevelopment to bring stormwater management up to current standards.

What are Minnesota code requirements for commercial storm drainage?

Municipal and state codes dictate flow rates, detention requirements, and water quality standards. We design storm drain systems to fully comply with local and state regulations.

Do you work with civil engineers and site designers?

Absolutely. We collaborate with engineering teams, GCs, and owners to ensure storm drain systems integrate properly with site grading, utilities, and pavement design.
