Tamil Nadu

This presentation provides information on the process that needs to be followed to construct a deep tube well for agricultural purposes in Pavalangudi village of Vridhachalam Taluk, Cuddalore district, Tamilnadu. The extent of area is 100 acres. The presentation covers three stages of ground water exploration - surface, subsurface methods, well development and the methodology adopted.

Symposium details in brief :

Aim: To discuss findings about all recent trace organic pollutants in the environment, its source, effects, and  control stragies.  Bioremediation of sites polluted with organic pollutants will also be emphasized.

The various initiatives taken up include modification in cooling water arrangement, condensate recovery for filter back washing, reuse of collected condensate water generated by anode casting, rainwater harvesting, conversion of gland packing pumps into mechanical seal, provision of electrolytic cell covers in refinery, control valve provision in storage tank steam

 Some of the initiatives taken up are, recirculation of fresh water from overhead tank for compressor cooling, reduction of sealing water in couch by use of anti friction bearing, refurbishing of steam and condenser circuit, sequencing of coloured laminating grade making, use of new generation centri-cleaner system, reduction of leakage of glandsealing water through use of mechanical seals, use of highly efficient imported vacuum pumps, reduction in consumption of make up water in cooling water, introduction of reverse osmosis system, utilisation of treated effluent water for irrigation and more.

The company has achieved this through recycle and reuse of wastewater, reducing water consumption by process changes, improving water efficiency in existing processes, implementing zero discharge effluent and reverse osmosis projects, reducing soft water consumption, eliminating water softener usage and using a new liquid surface conditioner.

It has achieved this through the use of dry low NOx burners, air cooled condensers, rainwater harvesting through building a pond, improving recovery in its reverse osmosis water treatment process and by increasing the cycle of concentration in its auxiliary cooling tower.

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

Ooty, Hotel Sunshine Inn | November 19-20, 2009

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.
