Isla Urbana Roof Storage Tank Gravity System¶
Rainwater & Storage • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
An aboveground roof storage tank that uses gravity to provide water pressure for household use in rainwater harvesting systems. Part of Isla Urbana's integrated rainwater catchment designs.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Rainwater & Storage |
| Capital Cost | Low-cost / Locally fabricated |
| 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. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
