Access to drinking water is a major concern throughout the world.
Health risks arise from consumption of water contaminated with pollutants or harmful chemicals that can transmit diseases such as diarrhea and polio.
Iran’s urban population has access to piped water as do 75% of rural inhabitants -- the latter is expected to reach 81% by 2021.
