SafeWater Wiki¶
The Open Engineering Wiki for Global Safe Water & WASH
An open-access, evidence-based technical reference library documenting sustainable water extraction, point-of-use purification, and low-cost infrastructure engineered specifically for developing countries.
💧 WhatWater.info Tool
Interactive techno-economic selector engine. Input your local geology, budget, water source, and population to find the exact matching water extraction and treatment technology.
❤️ Better-Water.info Directory
Independent charity directory auditing the cost-effectiveness, lifespan, and capital expenditure of real-world water charity programs globally.
📰 WASH Sector News & Insights
Curated breakthroughs, peer-reviewed field reports, and technology developments across the global rural water sector.
🎯 Wiki Mission & Core Pillars¶
Over 2 billion people worldwide lack safely managed drinking water. While vast sums have been invested in rural water systems, historical studies by the Rural Water Supply Network (RWSN) and IRC indicate that 30% to 40% of installed hand pumps fall into disrepair within 3–5 years due to supply chain failures, inappropriate technology selection, or lack of local maintenance capacity.
SafeWater.wiki bridges the knowledge gap between academic research, field engineers, community technicians, and development practitioners.
