Mumbai gets its water from a complex network of pipelines, tunnels, balancing reservoirs, pumping stations and lakes. Despite being one of the world’s largest water supply networks, why does Mumbai still struggle with water supply? These questions led the conversation.

The first question was about water demand and supply. How much water does Mumbai need and how much does it get?

“‘Need’ has various calculations, one of them being MCGM claims to calculate as per the Chitale committee report: 240lpcd” said Sitaram Shelar. 

Is there a disparity between how much water the rich get as compared to the poor? and how far are we from getting WHO recommended water supply per capita, which is 135l per day? Were additional questions asked.

“Mumbai sources around 4175 megalitres of water per day, and 100% of this is from the dams” said Sitaram Shelar. But, are we utilising all our resources?

The second question was on how Mumbai sources water and how it is carried into the city.

Water, however, remains more contaminated in some parts of the city like Dadar, Dharavi, Sion, Goregaon and Mulund according to the BMC’s water contamination report of 2020-21.

Is there a regulated rate of water? Who is paying how much for water?

Apartments buildings pay 4.23rs/1000ltrs and slums pay 400-500rs/1000ltrs

The fourth question asked if we are implementing any regulations to conserve water, is there incentive for good work, or penalisation for bad work?

“Dubious activities like filling ponds to create land, Constructing roads around the existing lakes are some examples of misuse of water resources” said Sitaram Shelar.

According to Sitaram and Purva, citizens’ constructive and consistent engagement, awareness about water sustainability and political will are the only ways to make clean water equally accessible to all.

Compulsory Cauvery connections won’t solve Bengaluru water crisis: Citizens, experts

As 80 wards in Bengaluru brace for severe water shortage this summer, the government's mitigation plans have drawn flak from many.

As summer intensifies, Bengalureans are once again worried about their taps running dry and the possibility of steep hikes in tanker water prices. Water shortage could be critical this summer in 80 wards, according to a study released by the Bengaluru Water Supply and Sewerage Board (BWSSB) last month. The study, resulting from a collaboration between BWSSB and the Indian Institute of Science (IISc), predicted a sharp decline in the groundwater levels of these wards by April. These wards, mostly located in the city’s peripheries, are dependent on groundwater. In a press release, BWSSB chairperson Dr Ram Prasath Manohar said…
