Water And The Laws In India, edited by Edited by Ramaswamy R Iyer, Centre for Policy Research, New Delhi. Published by SAGE Publications.

Laws relating to water in India have diverse origins, including ancient local customs and the British Common Law. The in-depth chapters in this compendium, written by luminaries from various fields, pertain to issues on water and proceed to a discussion of the legal questions that arise. This volume thus straddles two domains, viz., (i) water-resource policy, management, conservation, conflict-resolution, etc., and (ii) water law. The book also briefly raises and explores the case for a constitutional declaration on water and an overarching national water law.

The book is an invaluable resource for policy-makers, planners and administrators concerned with water at the Central, State and local levels; students, academics and practitioners in the domains of water as well as law; and social scientists, NGOs and activists concerned with the various issues discussed in the book. It should be useful as a main or supplementary textbook in universities and research or management institutions where any aspect of water (engineering, ecological, legal, social, economic, management or other) is a subject of study.

A list of contributors to the book is as follows:

Are Pumped Storage Schemes Beneficial For Harnessing The Krishna River Water Further (1995)

We foresee that this data can be useful in making rainwater harvesting and water balance estimates, in various research areas, climate change adaptation studies and more. We also believe in the democratising effect of having this kind of data freely available to the general public.

This report includes the findings of a study by the Planning Commission sponsored by the World Health Organisation and The United Nations Children's Fund (UNICEF) that conducted an assessment of the water and sanitation situation in India in 2002. The assessment revealed that:

This article on the Planning Commission site presents a review of the government figures regarding coverage of all rural habitations in the country with good drinking water supply.

To measure how fast water percolates into the soil, you need to measure the time it takes for a specific amount of water to soak into a specific area of soil. The easiest way to do this is to get a length of cylindrical pipe that is sharp enough to push (or hammer) into the soil at one end. Mark it with two lines – one is the line to which you insert it into the soil, and the other is the line to which you fill the water.

You can measure slope by making use of gravity. Find a protractor for measuring angles. Attach a straw across the straight edge of the protractor.

The ideal farm pond should be dug into the ground in a naturally low-lying area. Some of the soil that is removed can be used to construct an earthen berm around the pond, which should be planted with trees and grasses for stability. The shade and wind protection provided by the raised mound and vegetation will reduce evaporative losses.

Where conditions are favorable, it is better to recharge the groundwater than to create surface ponds for storage. This approach minimizes evaporative losses, and often improves water quality. Recharge structures can be anything from a small pit simply dug into the soil, to a borewell converted for recharge. Recharge structures are useful in sloping landscapes where the water would not otherwise have time to sink into the ground before running off.

Where possible, it is much more cost effective to restore existing tanks, than to build new tanks. Restoration can involve silt removal to increase the storage capacity of the tank and reduce evaporative loss. The silt can be used to restore the earthen bund, and any remaining silt can be applied to nearby farmland. The outflow structure can also be improved.
