Water Supply

The Brihanmumbai Municipal Corporation (BMC) is trying to commercially sell sewage treated water. As of now, the city generates about 2190 million litres per day (MLD) of sewage or black water, of which it manages to recycle 22.65 MLD of water fit for reuse for non-potable use. Citizen Matters examines the status of this project and how it could help the city with its water requirements. What is the BMC doing with its sewage waste treated water? In December 2023, the Brihanmumbai Municipal Corporation (BMC) invited bids for commercial use of 15.8 MLD of treated sewage wastewater generated from its…

If you have travelled on the new Airport Road to or from Bengaluru, you would see the quarried hill in Bettahalasur, a village near the outskirts of the city that looms large on the westward horizon. Abutting this quarry is the old village of Hunasamaranahalli, now part of Bengaluru’s peri-urban area. In a narrow lane in Hunasamaranahalli, there is an open well. This is its story. At a time of an acute water crisis, this story holds many lessons for us in Bengaluru. From quarry to community: The story of an open well A couple of years ago, Hunsmaranahalli and…

As Bengaluru struggles with an ongoing water crisis, it reports a shortage of about 500 million litres of water every day. The significant water problem in the city is frequently blamed on insufficient rainfall, unregulated groundwater exploitation, and environmental negligence. However, it is essential to investigate water contamination, notably from sewage and industrial effluents, as a major cause of the water crisis. The focus then moves to Shivpura Lake in the Peenya Industrial Area.  Although a key industrial area, Peenya is neglected, as evidenced by its poor infrastructure and pollution issues. Shivpura Lake, in particular, is contaminated by the surrounding…

The Cauvery River is located 100 kilometres away from Bengaluru, 350 metres lower than the city’s elevation. The Bangalore Water Supply and Sewerage Board (BWSSB) has to spend approximately Rs. 3 crores per day as electricity charges to pump the water over such long distances. The city’s dependence on Cauvery as its primary water source prompted us to analyse this issue at the recently held 'Bengaluru Water Datajam', held by Opencity.in. Since the extraction of water from the Cauvery is recent (just 50 years ago), how did Bengaluru operate its water needs before the onset of rapid urbanisation? Since, we…

Within just a few decades, Bengaluru has grown into the third largest city and the fifth largest metropolitan area of the country, with over 13 million people. The city’s rapid development is evident in the rise of built-up area, which has increased 37.4% in 2002 to 93.3% in 2020. In just 40 years, the extent of water bodies has reduced from 3.4% (1973) to less than 1% (2013), placing Bengaluru’s water resources under tremendous stress. Consequently, the city has come to depend heavily on Cauvery water and private water tankers or individual borewells to meet its daily demand. The overexploitation…

A popular quote by WH Auden says, "Thousands have lived without love, not one without water." I am deeply convinced that it is true, especially in present times, where the planned urban cities are facing acute water shortage on a regular basis, along with rural and remote areas. One of them is Dombivli. Dombivli, with its rapidly expanding population and insufficient infrastructure, has been grappling with water scarcity for years. I live in an integrated smart city with more than 100 residential buildings built near Dombivli. Currently almost 2,00,000 citizens reside in more than a 1000 flats. Facilities such as…

At the best of times, mornings in a family of four are probably exhausting, particularly for women. Ensuring that everyone eats, gets dressed, heads to school or work on time and in one piece can be chaotic. But mornings in a hot Bengaluru without water is downright soul crushing, says Kala, a 38-year-old woman living in Krishnanapalya. The water shortage in several parts of the city has disrupted the lives of low-income families and put public institutions like schools and hospitals on the edge. Krishnanapalya lies in east Bengaluru. Unlike the 110 villages in the peripheral areas of the city,…

In 2011, the Thoraipakkam Village Panchayat was incorporated into the Greater Chennai Corporation (GCC) limits and the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) rolled out schemes promising piped water supply and underground sewage system for the residents in the area. The move brought hope to the residents as we had waited for these basic amenities ever since we settled here in the 90s. But our anticipation turned to dismay as even after more than 10 years, these schemes remain merely on paper — incomplete on the ground.

In the backdrop of a city reeling under water shortage, Opencity held a Bengaluru Water Datajam on March 3rd to look at what data says about the state of water supply in the city, and what can be done to improve the water situation even in dry years. The event was held by Opencity in collaboration with Well Labs, MOD Foundation, Bangalore Apartments Federation (BAF), and Biome Environmental Trust. In the day-long event, 32 participants from varied backgrounds, including urban planners, GIS experts, software developers and other active citizens joined hands to analyse public data in the context of water…

Apartments in Bengaluru, especially in the peripheral areas such as Mahadevapura and Bengaluru North, which are dependent on groundwater or tanker water, are being compelled to take some drastic measures of water rationing. But even amidst these dire situations. there are implementable solutions. Here is an example of an apartment that took strong measures to conserve water, despite being serviced by BWSSB: Floriana Estates Apartment, a 19-year-old building in Koramangala, recognised the importance of water conservation as a social responsibility and for sustainability. The Managing Committee (MC) of Floriana Estates took several initiatives, including raising awareness, addressing water wastage, fixing…
