| Primary Mechanism | Rainwater collected from rooftops is stored in a tank positioned at a high elevation (e.g., on a roof or raised platform). Gravity provides sufficient pressure to distribute water to point-of-use taps without pumps. The tank is typically closed to prevent contamination and algae growth. |
