Some ideas at integrated urban water management looking at the hydrological and ecological cycles.

1. Water Management and
Conservation for a Sustainable
Future
S.Vishwanath

4.  Social – In which a clear Universal access has to be
defined with water as a human right
 Technical – where a mix of appropriate technologies
are selected
 Institutional – an integrated water management
institution is created
 Financial – where financial sustainability is achieved
 Legal – the legal right to water and pollution
prevention is exercised
 Ecological – the true ecological preservation of the
water environment from forests to sea is achieved

5. The Cauvery river basin Payment for Ecological
services
Bangalore

6. Bangalore
A city like Bangalore gets its water from the Cauvery 95 kms and 500 meters below
the city

7. Law of the jungle – need for a river basin institution

8. Old forest release water or do they?

11.  Over 30 million wells and bore-wells
 Over 60 % of our total water requirements
 Over 85 % of our drinking water needs
 ..and the only source for recharge is RAIN
 How is groundwater managed in a city ?

12.  Get back to the culture of the open well

14.  Map micro-watersheds and plan/implement
along it
 Map sub aquifers and draw a management
plan for it .

26.  Open wells are generally free from Fluorides
andArsenic
 Open wells have the lowest cost water
 Open wells have the lowest embodied energy
 Aquifers need recharge
 Aquifers need water safety plan to protect
from pollution.

62. EVERY ROOF CAN BE A CATCHMENT

63. Rain barrel : easiest way to begin rainwater harvesting

64. Rain barrels at work

65. Rainwater harvesting in an industry
4 acres > objective 0% runoff
Rain Barrels harvesting rooftop rainwater

69.  184 out of 219 towns in Karnataka do not
