Municipal water undergoes chlorination to kill pathogens; however, residual chlorine and potential chemical pollutants remain concerns. Boiling is recommended.

Source of Water in Chennai, India

Chennai's tap water primarily comes from the Chembarambakkam, Poondi, and Red Hills reservoirs. These store rainwater collected during monsoon seasons.

Additionally, groundwater sources like wells and boreholes supplement supply, especially during dry periods. Over-extraction sometimes leads to depletion and contamination risks.

Desalination plants also contribute, converting seawater into potable water to meet the city's increasing demand and reduce dependency on reservoirs.

Chennai Drinking Fountains

Public drinking fountains in Chennai may pose health risks due to potential contamination and maintenance issues. Water quality is not always regularly tested.

Bacteria, viruses, and chemical pollutants can be present if fountains are not properly sanitized. Use caution before drinking directly from them.

Using personal water bottles with filters or consuming bottled water is generally safer. Boiling water beforehand is advisable if unsure about quality.
