Mechanical septic tank cleaning
The intrepid S. Vishwanath chances across a sanitation innovation Posted on 19 Apr, 2008 05:43 AM

These trucks with a built in pump suck out septic tanks and pit latrines for a fee of Rs 1300/- ( 33 US $). They do the job cleanly and in 15 minutes. The waste is then deposited at a sewage treatment plant or for farmers to compost and use as fertilizer. A protocol for safe handling of the manure needs to be quickly developed as well as to tell farmers how much manure to use.

Persian wheel : The water lifting device in Kolar, Karnataka
S.Vishwanath and Amitangshu Acharya document their visit to one of the last extant Persian wheels in the Kolar District of Karnataka Posted on 22 Jan, 2008 11:26 PM

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.
