Catch the Rain, Bengaluru: Rainwater Harvesting in the City event poster

Monsoons are here and who doesn’t have happy memories of the fragrance of the first rain bringing along with it the much-needed relief from the weary heat of the Bengaluru summer. But then, along with memories, rains also bring inconveniences like localised flooding in urban areas and increased commute time! 

In recent years, we see many Bengalureans struggling to access water during the summers. And one wonders where all the excess water from the rains disappeared. 

Data shows that Bengaluru typically receives the highest rains in the months of August, September, and October. With August not too far away, now is the right time of the year to begin thinking about how rainwater can be used to address water issues faced by communities across Bengaluru.

This year also happens to mark the 12 year anniversary of Rainwater Harvesting being made mandatory in Bengaluru. The Bangalore Water Supply and Sewerage Board (BWSSB) Act, 2009 declared that Rainwater Harvesting (RWH) systems are compulsory. 

Over the years, BWSSB has come out with rules and regulations designed to encourage citizens and establishments to adopt rainwater harvesting. Recently, important updates have been made to the rainwater harvesting rules and regulations. This calls for awareness among citizens about the latest changes and how it affects them. 

BWSSB has also set up the Rainwater Harvesting Theme Park in Jayanagar where citizens can see for themselves the various RWH structures on display and get advice. 

According to BWSSB, Bengaluru has close to 1,55,000 properties that harvest rainwater, which makes it the second-largest number of installations for any city in India, next only to Chennai.

    Can filtered rain water can be used directly to the borewell….is that there will be a soil erosion between the casing pipe and rock formation…

  3. Krishna Iyer Balasubramanian says:

    At several roads in Malleswaram many rain harvesting pits were dug, lined up with concrete rings and properly top closed. Good work. However the channel leading to these are blocked by muck, debris.I am a senior. Some one should get them cleaned. Seminars are ok. Participants should walk around first, get this job done, if we are serious. Thank you friends

  4. Joseph says:

    BWSSB has already started putting fines in monthly bill for this new water harvesting bill. There is no problem for drainage chocking and non maintenance of sewage. Put new rule and give more penalties is the best way for revenue management system

Rainwater harvesting: Why don’t Mumbai societies do enough?

Rainwater harvesting, which is crucial for water conservation, needs space, dedication and funds. Mumbaikars are reluctant to make the effort.

“Does Mumbai feel the need to conserve water?” asked Sanjay Ubale, executive board member of Mumbai First at a conclave about water in Mumbai. With easy availability of water from seven reservoirs, the city has the best per capita water ratio in India, and so, there is less incentive to conserve water or practise rainwater harvesting, he explained. Why would societies spend funds to store water for future use when they are getting water at highly subsidised rates round the year, he asked. Statistics too suggest the same.  Approximately only 3000 societies of the total estimated 20,000 societies in Mumbai…

Explainer: How to start rainwater harvesting and why Mumbaikars should do it

If rainwater harvesting is implemented on a large scale in Mumbai, it will help in water conservation and reduce floods too.

Mumbai may have witnessed heavy rains but one must not forget that the city is still reeling under a 10% water cut since June 5, 2024. On the one hand water levels in the reservoirs are depleting, and on the other hand rainwater continues to flow out. In such a scenario, rainwater harvesting can be the game changer for Mumbai. If done right, it ensures water supply for individuals, fights larger water crisis and might help reduce floods too.    Urban local bodies (ULB) like the Brihanmumbai Municipal Corporation (BMC) have been encouraging housing societies to set up rainwater harvesting…
