From May 2006 up to before the earthquake hit, Dlo Pwop and Washington, D.C.-based partner International Action had jointly installed 140 chlorinators on water tanks in neighborhoods, schools, orphanages, and hospitals throughout Port-au-Prince, providing over 400,000 Haitians previously exposed to waterborne diseases like cholera, typhoid, hepatitis, and chronic diarrhea with a supply of clean, safe water.
