As ground water levels decline in India, Persian Wheels cannot reach the water to draw them out from open wells. One such Persian wheel stands forlorn and frustrated as the water table has dipped in Kolar, Karnataka India. This wheel has worked for the last 80 years and 2007 was the first time that the water table fell and the wheel could not work for the day.

A slow sand filter built with Japanese aid is running out of use because the community cannot repair the broken pump. Can we help organize the community to take charge of its asset?!

There is a spurt of gastro-enteritis in the city today. Residents think that it is the contaminated mains supply from the BWSSB that is the source of the gastroenteritis. The Bangalore water supply and Sewerage Board thinks it is water bought by residents from the private water tankers that is the cause but then seems to change its mind.

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.

Two simple technologies for water purity:

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
