Success Stories and Case Studies

This study presents a remote sensing based rapid watershed health appraisal of NWDPRA watersheds of Rajasthan. The study area is distributed across 8 agro-climatic zones ranging from desertic western plain to humid southern and south-eastern plain. The satellite data prior to treatment year (1988) was compared with post-treated year (1996), to reveal the noticeable changes over a span of 8 years.

The study is based on a scoping study on ‘Developing Markets for Watershed Protection Services and Improved Livelihoods in India,’ which Winrock International India (WII), New Delhi, undertook as part of a larger international study being carried out by the International Institute for Environment and Development (IIED), London. 

This deals with the Thames Water Ring Main Extensions and its plan to increase the area served by its London Ring Main by constructing two extensions in a £90m project.  The tunnelling will take place in north-east and south-east London and will help Thames Water to meet the capital's growing demand for water. The Ring Main was built to improve the speed and efficiency of transferring supplies of drinking water across the capital. 

This deals with the Deep Tunnel Sewerage System (DTSS) which has been developed as an efficient and cost-efficient solution to meet Singapore’s long-term needs for used water collection, treatment, reclamation and disposal. Conceptualised and managed by PUB, it was conceived as a cost-effective and sustainable solution to meet Singapore’s long-term used water needs.

At Delhi, there are dirty waste water rivulets, “nallahs” crisscrossing all localities and adding to the pollutant load of the river Yamuna. The situation is alarming with today’s count of nallahs standing at more than 22 Nos. These urban drains are nature’s creation and are meant to convey storm / rain water from upstream areas to downstream, finally leading to the river.

These presentations deal with a case study of the work done in Chicago City in the United States of America to improve flood management and water quality. In order to save construction costs, the reservoir side walls are composed of geomembrane liner over compacted clay.

This article by Dr. Prakasham Tata traces the author’s childhood dream of doing something to improve public health in Vizianagaram by ameliorating the conditions of Pedda Cheruvu and to provide a better environment around its historical centers, namely the fort, music college, clock tower, arts and science college, and the park housing the tombs of the maharajas. 

A major problem faced by the towns and cities across the world is the dealing with the huge volume of wastewater generated everyday. The wastewater is either treated with high costing conventional water treatment procedures or let untreated into rivers or other water bodies.

This case study from FAO deals with participatory watershed management at Ralegan Siddhi village in district Ahmadnagar. In recent years the notion of sustainable development has emerged as a reaction to the highly technological and centralized processes that have governed thinking on development, the green revolution being a classic example.
