Safe WASH (Water, Sanitation, and Hygiene) is essential for human health, well-being, and community resilience. Drinking unsafe water leads to health issues like diarrhea, while untreated excreta contaminates water sources for various purposes. Chemical contamination, whether natural or anthropogenic, poses a persistent health risk. Adequate WASH is vital in preventing Neglected Tropical Diseases (NTDs) like trachoma and helminth infections.

During the Millennium Development Goal (MDG) period, significant progress in water and sanitation contributed to a 50% reduction in diarrheal deaths. Improving service levels, such as regulated piped water and proper sanitation, markedly enhances health by reducing diarrheal disease deaths, highlighting the critical role of safe and sufficient WASH.
