On, OoruLabs, India's premier urban issues podcast, Sathya Sankaran, Host of OoruLabs talks to Vishwanath S on the new way of water management that the rest of the cities in India can adopt. Nothing like a crisis to change the approach and try new things.
The conversation discusses the water situation in Devanalli, a town in Bengaluru, and how wastewater treatment can address water scarcity. The town was dependent on deep bore wells for water, but many were dysfunctional and had high salinity. To address this, treated wastewater from sewage treatment plants is pumped into a lake, which then filters through the earth and recharges the aquifer. The water is then treated and supplied to the town. The conversation highlights the importance of local water sources, the symbiotic relationship between the city and its surroundings, and the potential for scaling up this approach in Bengaluru.

Takeaways
Treated wastewater can be used to address water scarcity and provide a sustainable water source.
Reviving lakes and recharging aquifers with treated wastewater can improve water quality and reduce energy consumption.
A comprehensive institutional setup and governance structure is needed to manage water resources effectively.
Groundwater management should be formalized and regulated to ensure sustainability.
Scaling up this approach can make Bengaluru self-sufficient in water and serve as a model for other cities.

In the era of only materialistic videos like how to become rich these type of videos are so refreshing 😊
Pull down all the CRUPPT Kannada people built over the lakes when i was a young boy Banaswadi lake was so big , These HARK THOO SPITTING politicians encroached ,And built fancy homes , These two fools talk talk talk , These open lakes ar encroached stare down the homes AND RECLAIM THE LAKE , BRIBE AND CRUPPUTION BUILDING WITH OUR SURVEY, ABOUT THE WATER, THESE TWO FOOLS TALK TALK TILL THE COW'S COME HOME , 36O LAKES DOWN TO 6O , NOW CRUPPT PEOPLE EAT AND DRINK RUPEES SHAMELESS
Talk talk till the cows come home
This is #1 idea must be implemented everywhere to combat upcoming water challenges .
Deep respect and thanks for the people coming together to make this happen.
Really inspiring, amidst all the bashing that the city gets these days, this work by Vishwanath Sir and his team is really great.
Lovely discussion. As always Vishwanath excels in communicating in vey simple language a difficult and a highly misunderstood subject.
Why can’t all IT BT companies in Bengaluru adopt 1 lake each , I m sure there are more than 10000 companies which can do these experiment using their 2% profit under their CSR initiatives
Unfortunately we live in a capitalist world, the corporates will invest only if their is profits for them
Excellent idea
but they want returns lol
Actually quite a few of lake rejuvenation efforts done by NGO's have been supported by corporates, including this one. Some lake rejunevations are getting tarnished in local politics which puts a spoke in the wheel. We need a concerted effort which is protected from local politics by authorities.
@@oorulabs I heard from the lake development authority, that the government has stopped giving permissions to NGO's for lake rejuvenation
Sir, what happens when "development" reaches these areas. The acquifer is being recharged not only by the shallow water store under lake, but fed by rainwater on open land. Once development reaches there, the concrete and metalled roads choke-off the open lands and stop feeding the acquifers. As Bangalore's population increases, the pressure on these surrounding rural areas would increase too.

@@oorulabs thank you sir, that sounds like a very good initiative. One can only hope that it'd be implemented in earnest and with all honesty, working closely with neighbourhood RWAs, relevant NGOs etc.
Amazing content, very informative and detailed. We tried recharging underground with rainwater at our house, but the water didn't percolate through the ground and instead stayed just below the surface. This caused damage to the roads and footpaths. Wish I knew about this earlier.
Nice work. Wishing other lakes in Bangalore and other places should be explored for similar recharge
The wastewater treatment by BWSSB in bangalore is good only for cleaning roads and buildings. It's totally unfit for cloth wash, shower, garden, farms let alone for kitchen use. The dozens of lakes which were earlier supplying water had been polluted by builders, some small scale industries with the blessings and guidance of BBMP officers since if these dried up, more real estates may be permitted
I think this video is abt, some ppl who stopped complaining and arrived at solutions
@zenrainman, sir why is the Doddabommasandra lake been dead from so many years?
Treated water along with rainwater harvesting is the way to go forward
Very insightful. Why can't we do the same for the lakes within Bengaluru? However small in number they are post encroachment, local water sources can help us a lot - ecologically and economically. It still puzzles me as to why we should pump water 100+ kms far for our city
it puzzled me as well, but over the course of the podcasts I learnt how we don't want to do hard work and take the easy way out even if it costs us more.
To be able to decommission the deep bore wells in the city and get onto the shallow ones, you first need the overall water table to rise. The problem with cities, vertical ones like Bangalore, is that usage of water per person per square foot of inhabited land is way higher than the recharge capacity of the entire neighborhood. Thereby making the water table drop very fast with the onset of the summers.... The best way IMO is to first make it mandatory to every house and building having bore wells to have a rainwater harvesting and storing capacity mandatory for at least the usage of that building or house for six months. After this you will see a gradual rise in the ground water levels over a period of 5 to 10 years.... Bangalore being on a hill (sort of) needs more deeper lakes around it.... not the ones in the city but the land that is seen flooded thoughout the year on the outskirts , there ponds and lakes must be made to store all that water and let it percolate instead of having it lay around in barren fields and evaporate before it can percolate into the ground. Just my 2 cents from what I have seen there...
Very enlightening discussion👍. Outstanding work done by the team of Vishwanath's👏. I think strict regulations should be introduced for water use in any form.
Aren't enough regulations there already and the thing missing is honest enforcement ? People seem to be flouting rules with utter impunity in many cases, in spite of regulations being there. One regulation that is sorely needed but missing is perhaps the one around not treating the borewell water as one's personal property to be squandered or consumed as one likes.
One of the solutions in S2E13 was to meter the borewell. You should watch that one too.
Can you please share names of fish which are suitable for wells ... so that wells are kept clean
Is there plan any plan like this to save Hoskote lake as well which is also very big but continuously being destroyed due to rapid urbanization. Please bring this to his notice
CRUPPT OFFICIALS CRUPPUTION SHAITANS question THEM get answers TALK TALK TILL THE COW'S COME HOME TWO FOOLS
Hello.Hello.Our factory is specializing in COD reagent ,Total Nitrogen Precast Reagent,Ammonia nitrogen Assay Kit,Water quality detection spectrophotometer.etc.Are there any distributors interested？
That turtle is lonely
ha ha.. indeed
Simple solution to water crisis, Cut the water supply to politicians. Let them use water after each and everyone in bangalore has enough water.
How good is the treated water coming out of HN Valley. Poor villagers being scapegoats of the experiment. Lot of voises heard where people have expressed the side effects like degrading agriculture farm, increase pests and diseases for crops and cases of cancer increasing in the areas around lake. If they do tertiary treatment of water then that water is safe. But it is not te case.
There are far more cases of cancer in the city with clean cauvery water.
@@oorulabs we have seen reports of the bad quality of kc valley water and hn valley water being used to fill up Kolar and chikkaballapur. Even Prof TV Ramachandra from IISc is asking government to do the tertiary treatment of water and fill the lake but not the primary and secondary treatment. They have totally debunked the theory of using filter borewell near the lakes filled with secondary treated water.
This is what I got... According to a 2019 paper, the Hebbal-Nagawara (H-N) Valley water in Chickballapur district, India, has a biological oxygen demand (BOD) that exceeds the 6mg/lit limit set by BIS. However, other parameters are within acceptable limits, and the water can be used for irrigation and groundwater recharge. The paper also suggests that the water can be used for drinking after proper filtration. Also TV Ramachandra has asked BWSSB to send the water in open channels instead of closed ones so aeration and photosynthesis can get rid of toxins. I don't know how much of HN valley channel is closed and how much is open, near the lake it was open. Tertiary treatment will be less relevant if this natural cleaning was employed. Do send me the studies of cancer, pest and disease increase from this water that you mention.
Big false claim
Benglore IT city (Insanely torchers) Auto driver goons Public transportation goons Huge traffic Pro Kannadigas braking english board North vs Kannadiga hate Water crisis Congress government Corruption Small streets Banglore is a nightmare city Better to move to Hyderabad for IT or Coimbatore
CRUPPT OFFICIALS CRUPPUTION SHAITANS QUESTION ONLY TO FILL THERE POCKETS , JUST TALK TALK make a special CRUPPUTION FORCE ,NOT TAKE BRIBES AND LOOK THE OTHER WAY
Andhbhakt hate monger is here, situations of cities in India are similar, no city is examplary
First of All who told you to come here? Go to your place
All cities will face water shortage in another 2vmonths if the rains are delayed
