Horamavu, part of the 110 villages added to Bengaluru city corporation limits in 2008, is not getting Kaveri water supply yet. Besides, with extensive digging of new…

The monsoon is just around the corner, and it will hopefully be bountiful. The water situation in Chennai presently is comfortable with Metro Water officials saying that the city has enough of this precious commodity to tide over one more year, irrespective of how the monsoon fares. The Chembarambakkam reservoir, one of the largest sources of water for the city, is already 85% full, necessitating a release to lower its levels so that it can accommodate further inflow during the monsoon. Elsewhere in the city, stormwater drains are being constructed to carry away water that is likely to otherwise stagnate.…

For the past 13 years, the residents of Old Mahabalipuram Road (OMR) have awaited piped water connections from the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB). Owing to the topography of the area, they do not have access to alternative sources of water like groundwater. This makes many of the residents of OMR completely reliant on private water suppliers. However, with rising costs and frequent threats of strikes by private tankers, residents have begun exploring solutions that reduce their dependence on external water suppliers. To this end, Central Park East, an apartment complex in Sholinganallur, has come up with…

Mohan*, a resident of Thiruvanmiyur, has piped water connection from the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) and a borewell connection at his house.

Mohan is one of the many residents across the city reliant on the…
