Recipe for greenery
The residents of Tara Apartments in Alaknanda, New Delhi, have perfected the recipe of maintaining the greenery in their complex, by simply recycling 10,000 litres of waste water everyday. As a result, now they have more water for meeting their other requirements.
It all started when Dr Pandey, a resident, got a sample of waste water from the apartments tested for its quality and, found that it could be reused.
Three months ago, a system to divert kitchen and bathroom water to a filtration system was put in place at a cost of Rs 60,000. Filtered water that comes out of the system is almost free of any colouring impurity or smell. To further improve the water quality, 250 gm of bleaching powder is used daily. The construction and minimal maintenance cost is borne by the residents. Presently, recycled water from only two blocks is meeting their demands.
Thrilled with the success of their endeavour the residents now plan to do rainwater harvesting according to the technical designs given by CSE. Recently, they approached the chief minister of Delhi for financial assistance to do rainwater harvesting.For further information:

Impossible, say most.
Stephen Salter, the innovator of the wave power device nodding duck, recently introduced his idea of a floating wind turbine that sprays water vapour high into the air, to increase evaporation from ocean and precipitation over land. He proposes to use the centrifugal force generated by the rotating blades to pump water droplets into the atmosphere.
On July 23, 1992, Shantilal Meckoni actually created rain in Mumbai by sprinkling silver iodide on flaming charcoal to increase cloud density, also called cloud seeding. Recalls Meckoni: "We started the experiment at 10.30 am at 10 sites. At 12.40 pm, it rained."
