Water Supply

Can Bengaluru be water resilient? Urban water researchers Rashmi Kulranjan and Shashank Palur from WELL labs have previously outlined how the city can reduce its dependence on Cauvery water, reuse groundwater and allow lakes to act as flood control systems. However, the first step to building water resilience is understanding the different sources of water in the city, how much water is used and how much remains. WELL labs released Bengaluru's first water balance in October this year, co-authored by Rashmi Kulranjan, Shashank Palur and Muhil Nesi. Here are the key insights from the report. Water management in Bengaluru Rashmi…

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. However, he has been unable to use both of these sources of water. This is because the groundwater levels are too low to draw water from the borewell and the piped water is mixed with sewage. Mohan has had to buy water from private water tankers in Chennai, regularly spending at least Rs 4,000 a month, to meet his family’s needs. Mohan is one of the many residents across the city reliant on the…

“Earlier, we would wash clothes by the riverside. But later we dug up bore wells in all dhobi ghats, which have become our main source of water,” says Mahalingayya, president of Karnataka Rajya Madikatte Ghataka that oversees the functioning of dhobi ghats across Karnataka. In Bengaluru, each dhobi ghat has at least two borewells. However, water scarcity is still an issue. The solution is using recycled water. But the cost and maintenance of water treatment plants are of primary concern. Water usage in dhobi ghats Each dhobi ghat uses varying quantities of water on a daily basis. The average can…

Mission Antyodaya database aims to create granular data for gram panchayats across districts throughout the country. The intention, as stated in Union Budget 2017-18, is to create a convergence and accountability framework by tracking the various development indicators across Gram Panchayats (GP). In Karnataka, the database provides information about infrastructure and schemes at the household level. I analysed the indicator of ‘Piped Water Connections’ across gram panchayats in Bengaluru.

Like many suburban areas of Chennai, Chitlapakkam has seen tremendous growth but the civic amenities and services have failed to keep up with the needs of the people. Residents of the area have banded together to fight for their rights and ensure that they are able to enjoy a better quality of life.  It is because of the spirit of the residents that the connectivity in the area has improved in recent times. Our campaign has brought back the S3 minibus to Chitlapakkam, along with the introduction of another minibus, the S100.  Buoyed by this success, residents have begun to…

"Why should we buy water from outside, if we are paying water tax to Metro Water for water supply?" asks S Bharathi, a resident of Besant Nagar. She gets water from the Nemmeli desalination plant but the water supplied is not potable. Residents have flagged various issues with the water being supplied from the plant for many years but with little recourse. The Nemmeli desalination plant has been operational since 2013 and supplies water to the southern parts of the city. The areas it covers include Sholinganallur, Neelangarai, Injambakkam, Karappakkam, Semmenchery, Thoraipakkam, Perungudi, Kottivakkam, Palavakkam, Thiruvanmiyur, Velachery, Taramani, Pallipattu, Adyar,…

Take a drive along Keelkattalai to Kamatchi Memorial Hospital any time during the day, and you will see hundreds of water lorries parked on the radial road. This stretch, 80% of which falls under Kovilambakkam Panchayat and 20% within the Greater Chennai Corporation (GCC) limits, is a hub of illegal groundwater extraction — one of the root causes of Chennai’s water woes.As it happens, there are four or five legitimate water drawing points near the Keelkattalai lake, but the lorries do not use those points to extract water. “A black hose has been laid illegally,  2 to 3 km away…
