This technique incorporates broad, shallow channels designed to intercept water before it collects.
Trench Drains: Ideal for large flat roofings, these systems frequently include grates to keep particles out while channeling water.
Catch Basins: Positioned tactically to gather rainwater and filter out particles.
5. Green Roofing Systems
These involve greenery on roofs that help in water absorption and management.
Comprehensive Green Roofs: Lower maintenance and need less soil depth.
Intensive Green Roofs: Require more upkeep with much deeper soil and a wider variety of plants.
