S.Vishwanath and Amitangshu Acharya document their visit to one of the last extant Persian wheels in the Kolar District of Karnataka iwp posted 13 years 3 months ago

img_0052.JPG What exactly is a Persian wheel? Also known as Rahat (in Urdu), it's a simple water lifting device, where a number of small pots are attached to a long chain. Two gear wheels make up the system and as the first one is revolved, the pots each dip and swallow water from the well and soon after pours itself out to a metallic shaft which in turns empties into an intricate network of troughs that distributes water adequately through the cropped area. It is believed that the technology originated in Egypt and as world shrunk through extensive trading, it spread to India and China.

Report on the CII-GBC National Award for Excellence in Water Management 2007, by S Vishwanath
S.Vishwanath, who was on the jury panel, reports on the National Award for Excellence in Water Management 2007, competition organised by the Confederation of Indian Industry. iwp posted 13 years 4 months ago


As the Indian economy grows at a rapid 9 per cent, the use of water by industries will also grow at 9 per cent. While agricultural use of water will continue to remain the largest consumer, it is expected that the demand from industries will show a rapid increase. Industries demand water at a point and also discharge water at a point and therefore sustainable management of water by industries is not only crucial to the industry itself but to the neighbourhood where the ind ustry is located. The Confederation of Indian Industries , CII , recently organised its National Award for Excellence in Water Management 2007 competition in the Sohrabji Godrej Green Business Centre in Hyderabad (http://www.ciionline.org/, www.ciigbc.org) . A range of industries participated in the competition organised in two categories - 'Within the fence' and 'Beyond the fence'. The way many industries highlighted their projects was an indication on how serious they consider the management of water resources. That it is identified as one of the key resources, apart from energy to be looked at as a critical input for sustaining growth, doesn't come as a surprise. Source to sink
