Can You Drink Tap Water in Chennai?

No, tap water is not drinkable.

According to WHO data, 93% of India cities/towns and rural areas have access to improved water sources, that are available when needed.


While in Chennai it is advisable to drink only bottled water. Do not trust water from small local restaurants as it may be from the tap, and avoid cold or iced drinks that are not commercially sold (Bigger chains of eateries and juice shops can be trusted to an extent). Eating fresh vegetables and fruits that have sat outside in the presence of insects can also be unhealthy, although bananas and coconuts are usually safe because they are opened only immediately before eating. Hot drinks in restaurants such as tea, coffee, and other local specialties are safe, as are packaged/bottled drinks such as Aquafina water, Frooti (a popular local mango drink) and others. If you have access to a stove, boiling tap water before drinking is also an option. Never eat from roadside shops as the food is prepared in the most unhygienic conditions.

Source of Water in Chennai, India

The current water supply from Chennai, India, originates from surface water and groundwater.

The present source of surface water is natural rainwater saved in three interlinked lakes: Pundi, Cholawaram, and Red Hills (see fig. 4.5). But, all three lakes are shallow and small in power. The whole water acquired from this system is approximately 250 million liters every day(mld).

The catchment area is agricultural so that, in years of rain, the inflow into the reservoirs reduces substantially since irrigation tanks, lakes, along with upstream diversion, have called on the available stream.

About 50 mld is extracted in well areas. Although groundwater makes a substantial contribution (equivalent to industrial requirements in the area), there are specific issues with aquifers that are shallow and have limited funds. As a result of the significant manipulation of groundwater, some delicate areas have experienced seawater intrusion. As a result, water from almost 40% of the wells is not of potable quality. Additionally, a significant recharge area from town is now covered by urban settlements, leading to a decrease in groundwater because of low groundwater recharge. There has to be a test on these agreements.
