Gravity-Fed Rural Piped Water Scheme (Self-Help Design)¶
Membranes & Advanced Filtration • Est. CapEx: $30,000 USD • Lifespan: 7–15 Years
Technical Overview¶
A design and construction methodology for gravity-fed rural water systems that are built by communities using locally available materials like PVC, asbestos cement, or steel pipes. It is intended for rural communities in developing regions to provide reliable water supply without pumps.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Membranes & Advanced Filtration |
| Capital Cost (CapEx) | $30,000 USD |
| Power / Energy | 100% Gravity / Zero Power |
| Target Scale | Village / Community (200–1,000+ people) |
| Standard Lifespan | 7–15 Years |
| Technology Maturity | Commercially Available |
| Primary Mechanism | Water flows from a higher elevation source (spring or reservoir) through pipelines using gravity. The hydraulic grade line (HGL) is used to design pipe sizes and ensure positive pressure, while air valves at high points release trapped air to prevent airlocks. |
