This approach incorporates large, shallow channels created to intercept water before it builds up.

Trench Drains: Ideal for big flat roofing systems, these systems frequently include grates to keep debris out while transporting water.

Capture Basins: Positioned strategically to collect rainwater and filter out particles.
5. Green Roofing Systems
These include greenery on rooftops that assist in water absorption and management.

Extensive Green Roofs: Lower maintenance and require less soil depth.

Extensive Green Roofs: Require more upkeep with deeper soil and a wider range of plants.
