The Big Necessity - The unmentionable world of human waste and why it matters By Rose George

This status report prepared by Development Alternatives contains brief background information about the Bundelkhand region, details about the physical profle (topography, drainage and river systems, land usage, climate, rainfall), water resources information (water demand, availability, supply and accessibility) and information on sanitation practices (toilets, personal  hygiene, solid waste management, liquid waste disposal, availability of water for sanitation).

The survey was done using a closed-ended questionnaire which was administered to key stakeholders including teachers, school children and sometimes the SDMC (School Development and Management Committee) members. All government and aided schools were included in the survey. 

The Sachetana Drinking Water project of the Government of Karnataka covers 15 villages in each of the taluks of Bagepalli (Chikkaballapur), Mundargi (Gadag), Sira (Tumkur) and Pavagada (Tumkur).

The baseline survey covers a representative portion of the villages and families of the above and contains the following information:

The presentation provides several water management measures including rainwater harvesting, grey water reuse, black water treatment and use and eco-sanitation in  Andaman and Nicobar islands. It also provides recommendations for modification in agricultural practices and other livelihoods that can be taken up with the given water availability.

This database aims to evolve suitable policy in the field of water supply and sanitation sector and is useful in analyzing the data for implementing suitable programmes in India. As a first step, it was proposed to collect data for all 423 Class I cities in the country, as per census 2001 in the already devised and approved formats for Water Supply Sewerage and Solid Waste Management.
