Two billion people lack access to safe drinking water, and 3.6 billion people do not have access to safely managed sanitation. Additionally, 2 billion people do not have access to handwashing facilities with soap. Every day, more than 700 children die from water-related illnesses.<\/p>

Access to clean water, sanitation, and hygiene services (WASH) is crucial for public health, impacting child development, educational outcomes, and economic productivity. By ensuring equitable access to services, WASH interventions improve community resilience against diseases and environmental challenges.<\/p>

PSI collaborates with local communities, governments, and private sector partners to create sustainable WASH market systems, ensuring accessible, affordable, and appealing solutions, allowing people to live happier, healthier lives.<\/b><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
