Here, surely, is a disaster in the making. Bangalore is using up much more water than it is recharging.


According to a 2010 study by Karnataka Groundwater Authority members, the city is recharging only 3,290 hectare metres of groundwater annually even as it exploits three times more than the recharge for various purposes.
The study reveals that apart from a steep increase in groundwater exploitation in Bangalore in recent years, there is also a considerable amount of wastage—which can be avoided if water is used and preserved judiciously.


“Bangalore is [spread over] an estimated 800 sq km,” says KC Subhash Chandra, hydrologist and groundwater expert member, Karnataka Groundwater Authority. “Of this, the built-up area is 560 sq km, with 240 sq km of open space. Naturally, there is a severe restriction of rain water infiltration into the ground.”


The study shows that only 6% of rain water is materialising into groundwater in the open areas.“Over 17,040 hectare metres of rain water is being wasted by being drained along with sewage water,” he says. “This is clean water that can be used.”


According to the study Bangalore receives 830 mm of rainfall annually, which amounts to 66,400 hectare metres of water. “Over 71% of the water is getting wasted in evaporation and transpiration,” Chandra says. “If the rainwater that is being wasted as run-off, amounting to 17,040 hectare metres, is saved and used, it can serve 23 lakh people—about 24% of the city’s population.”


The Bangalore Water Supply and Sewerage Board (BWSSB) supplies 35,605 hectare metres of water to the city. “According to BWSSB data, the population will increase to 95 lakh in 2020, and the requirement of water will go up to 48,600 hectare metres,” Chandra says. “How will they increase to this number? Only 27 hectare metres of water is being added to the Cauvery Stage IV now. This will not suffice in another 10 years.”


Bangalore is currently facing a shortage of 11,226 hectare metres of water.

Hi

I am planning to buy house/flat in Bangalore where Water Problem is NOT there.

At least ground water level should be sufficient for 20 years... I don't mind to go little bit outskirt ...

Could you please suggest where we do not have water problem...

Thanks

Will less ground water table reflect in real estate investment?

As far as Bangalore is concerned the southern parts of the state is rapidly developing at a sky rocketing rate. Due to considerable increase in population density the ground water usage is exploited at a rapid rate. Will this scarcity gets reflected in fluctuation of the the real estate exchanges?

i don think so , coz almost all new developments are dependent on tanker water .
Real estate developers are not pricing their apartments based on whether there is ground water or not.

When I was staying in Challaghatta (near old airport) I used to see line of tankers filling their load and departing to different parts of the city. (Challaghatta is landlocked by the airport, Defence establishments and Iblur firing range it still has some water left). So as long as the tankers are running, water will be supplied to whoever can pay for it. I imagine that as the water table gets lower the tankers will come from even far away places.

You will have to buy near lakes, but doing that has it's own set of problems.
