This method integrates large, shallow channels developed to obstruct water before it collects.

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

Catch Basins: Positioned tactically to gather rainwater and filter out particles.
5. Green Roofing Systems
These include vegetation on roofs that assist in water absorption and management.

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

Extensive Green Roofs: Require more maintenance with much deeper soil and a wider variety of plants.
