In an earlier post Microfinance for Water - How would it Work? I had put up a picture of a woman drawing water out from a pit.

The ASCE Environmental & Water Resources Institute (EWRI), is organising the 3rd International Perspective on Current & Future State of Water Resources & the Environment from 5th to 7th January 2010 in Chennai.

EverythingAboutWater Training Workshop on Rainwater Harvesting & Groundwater Management

For a GIS zealot like me, this is breaking news on the Indian mapping front. Finally a GIS application for risk-mapping and management of floods in India!

The Flood Risk Mapping Study, funded by the Water Resources wing of the Public Works Department to a tune of Rs 2,17 crores, is an initiative of the Tamil Nadu State Government. It is supported by the Centre's Department of Science and Technology and Survey of India in the research component of the project. This one-year project is being handled by Anna University’s Institute of Remote Sensing (IRS), Chennai.

Lately there have been some conversations about water sector and microfinance, about bringing in microfinance to address water issues like access to clean drinking water, household water distribution and supply, associated problems of sanitation like underground drainage, and utilities.

This paper describes the findings of a study that was conducted to validate the findings of earlier studies and observations that have been conducted in ancient texts in India that describe termite mounds as useful indicators for groundwater exploration.

Depending upon how you see it, in the geographical expanse of India a train journey could be anything that one would wish it to be ...

This research study, by Veena Srinivasan, addresses the challenge of supplying water to rapidly growing cities in South Asia, using evidence from the water-scarce city of Chennai. Chennai (formerly Madras) is a rapidly growing metropolis of over 6.5 million people, whose infrastructure has not kept pace with its growing demand for water. In the year 2003-2004, Chennai experienced a severe water crisis, the piped supply for the entire city was virtually shut down for a 12-month period. Consumers became dependent on private tanker suppliers trucking in untreated groundwater from peri-urban areas.

Chidambaram is the taluk headquarters, located at about 250 km south of Chennai on east coast road [ECR] in Cuddalore district of Tamilnadu. It is a coastal taluk having three panchayat unions, Keerapalayam, Melbhuvanagiri and Portonovo. Chidambaram is the most important pilgrim center of the country, and is blessed with the Lord Nataraja temple. The temple town is also known as Bhuloka Kailash and Lord Nataraja, a cosmic dancer, represent the ‘Aakash’ form which is one among the ‘Pancha Boothas’. 

Though this temple town is blessed with such historically important temple, the Nature has cursed Chidambaram area with brackish water, which is also one among the ‘Pancha Boothas’. The total aerial extent of this taluk is 649 square km and the most part of the taluk is confined between the rivers Vellar and Kollidam, which is a distributary of the river Cauvery. Some few lakhs years back the Kollidam river might have flown even north of Chidambaram town and might have receeded subsequently southwards to the present position. Due to this invasion, the entire area might have been changed as marshy lands and mangrove forests. The salinity of ground water may be attributable to the fluvio marine origin sediments, which might have been deposited during this paleo invasion by the river and due to the back water flow. Chidambaram is about 15 km west of sea shore and the mean sea level is 5.1 metres. Geologically this taluk is a sedimentary terrain and the eastern parts are covered by the quaternary unconsolidated formations of clay, black clay, soils, alluvium, silts, kankar and laterites of recent to sub recent age and the western parts by the tertiary formations of Mio-Pliocene age represented by litho units - sand stones, grits, clays with lignite seams and pebble beds.
