800 - 900 LD of water pupmed to Bangalore from Caveri river and transported over 100 Kms along with other water sources of 250 MLD apart from the borewell run with tankers.
This is apart fro what Bangalore receives rain all 12 months which no other Big city in India receives.
Presently city has 14 Sewage Treamtent plants to treat the water by BWSSB with installed capacity of 720 MLD with operating at just arround 300 MLD level.
Out of these 5 are located in North Bangalore :
Yelahanka, Hebbal, Jakkur, Raja Canal STP, Nagasanndra.
City center has only two STP : Cubbon Park, Lalbagh
East Bangalore has only two : KR Puram and Kadabeesanhallai, west Bangalore hardly any thing.
South Bangalore is slightly better.
Looking at how ground water is going down to even 1000 ft is very shocking in Bangalore. Sae time we have floods on the roads and ore then 4000 tankers are playing.
So with individual citizens who has more then 2400 Sq Ft to impleent rain water harvesting with apartent, where does the gove buildings, factories, big complexes fit in doing rain water harvesting.
So when apartment complexes are doing their own STP, where does BWSSB fits in not taking care of complet sweage water treatment ???
why does the lakes in Bangalore are drying up with 800 MLD water beeing puped ???
If things are done in good intention in Bangalore, I feel all lakes in Bangalore can be filled with recycled water in just 10 - 20 days of time, this can be possible only if the drain along Mysore road does not receive even single drop of sewage water.
Why is GOK is sleeping in not establishing more STP plants and ake existing efficient. Then we will not see any flooding on roads in Bangalore if these are done.
