Iran: Water Supply and Sanitation
Country Study > Chapter 2 > The Society and Its Environment > Health and Welfare > Water Supply and Sanitation


In the mid-1980s, polluted water supplies remained one of the main reasons for the high incidence of parasitic and gastrointestinal diseases. Tehran and other large cities had chlorinated water systems, but contaminated water has continued to be a major problem in the smaller towns and villages. The disposal of waste also remained unsatisfactory. Tehran in 1986 still did not have a sewage system serving the entire city. Most of the other cities had only partial sewage systems, and in small towns and villages there were none at all.
