Diarrhea disease is the second leading cause of death in children under five years old. It is both preventable and treatable. Each year diarrhea kills around 760000 children under five. A significant proportion of diarrhea disease can be prevented through safe drinking-water and adequate sanitation and hygiene. Globally, there are nearly 1.7 billion cases of diarrheal disease every year.  Diarrhea is a leading cause of malnutrition in children under 5 years old. Diarrhea is usually a symptom of an infection in the intestinal tract, which can be caused by a variety of bacterial, viral and parasitic organisms. Infection is spread through contaminated food of drinking water, or prom person-to-person as a result of poor hygiene. Diarrhea can be treated with a solution of clean drinking water. Rizq foundation is focusing on this issue, so we have been installed RO Plant in various places of Sindh  for provision of clean drinking water facility at local level. We have planned to start RO Plant in different areas of sindh and soon our program will be expanded in overall Pakistan with the help of local funding institutions and donor’s contribution.
