Wells and Step-wells

For the total of 6-lakh households in Thrissur district, there are a total number of 4.5 lakh open/dug wells. As per the 2001 census, 71% of the total population of the district depends on open wells for drinking. Estimates indicate that the aggregate household investment in open wells comes to about Rs. 1,800 crores and the wells have a combined capacity to yield 6.6 million m3 per day. Though the average annual rainfall of the district is about 3,000 mm, about 70% of these wells are non-perennial. Additionally, because of heavy surface run-off, groundwater levels in several blocks have fallen sharply, and coupled with saline intrusion at an accelerated pace, have led to water quality problems. In order to address the issues of quantity, quality and sustainability, the Thrissur district administration in collaboration with the PRIs have launched a process driven, participatory well re-charge programme called Mazhapolima, with an overall goal to improve the health and welfare of communities through improved access to drinking water.

"Megh Pyne Abhiyan" is a network of NGOS that has been working in flood affected areas in Bihar with Arghyam support for the past few years. MPA has been grappling with the idea of providing clean water and sanitation in Bihar.

Both Mohenjo daro and Harappa reported wells in every household and also community wells. They are perhaps the oldest in the subcontinent. Here is one open well from the Konark temple in Orissa. These must have been the sole providers of good clean water during that time and one of them continues to provide water for the repair work underway.

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.

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.
