This document discusses sustainable water management and conservation. It addresses water issues from social, technical, institutional, financial, legal, and ecological perspectives. Specifically, it notes that groundwater provides over 60% of total water needs and over 85% of drinking water needs in many cities. However, groundwater is often poorly managed. The document calls for mapping micro-watersheds and sub-aquifers to develop management plans, protecting aquifers from pollution, and harvesting rainwater, such as through the use of rain barrels on rooftops. Overall, the document advocates for integrated, sustainable water resource management.

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
have a SewageTreatment Plant
