Project Overview

Nestled in the mist-laden ridgelines of Eastern Nepal, Khijiphalate village faces a stark water crisis. Springs are drying, wells are absent, and surface water is non-existent at this high altitude. For the 107 residents—primarily women and children—the daily search for clean water is long, physically taxing, and worsening with time. The once-thriving Samtenchhuling Monastery, a vital educational center for Buddhist teachings, had to close due to water scarcity, forcing students to carry water uphill and abandon their studies.

Key Impacts

Water Access Restored: Over 500 liters of clean water are now available daily, meeting the essential drinking water needs of 15 households and reviving the potential for the monastery's future re-opening

Reduced Drudgery: Women and girls, once burdened by long walks for water, now have access nearby—freeing time for education, income generation, and improved wellbeing

Community Empowerment: A sub-committee under the Water Users Association (WUA) was formed—including at least 50% women and youth—trained in operation, maintenance, and monitoring of the system

Local Ownership and Sustainability: The fog harvesting system is maintained by locals using local materials. The WUA now manages the infrastructure independently

Climate-Resilient Innovation: This model aligns with Nepal's National Adaptation Plan (2021–2050), integrating water supply, sanitation, and climate resilience in remote areas

How It Works

  • 1
    Fog Harvesting Panels: Polypropylene mesh panels are installed on ridgelines to capture water droplets from the fog
  • 2
    Storage & Filtration: Water is channeled into 10,000+ liter tanks and treated with a micro-filtration system for safe use
  • 3
    Distribution: Water is delivered via gravity-fed community taps and can be extended to homes through HDPE pipes
  • 4
    Sustainability Features: Greywater reuse for home gardening and seasonal recharge ponds optimize year-round water use

Scalability & Future Outlook

This project isn't just a solution for Khijiphalate—it's a scalable model for other water-stressed Himalayan regions. By working with local municipalities, the findings and recommendations from this initiative will contribute to future climate adaptation plans (LAPA) and national water security strategies.
