India's dependence on the underground aquifer especially deep bore wells are well known. With over 22 million wells India has perhaps one of the largest such structures in the world. Since most of peninsular India is hard rock with basalt/granite/gneiss underlying they present a particular challenge for understanding.

I was in Bhavnagar - Saurashtra, Gujarat and came across rooftop rainwater harvesting works implemented by (one more than 10 years ago) by Utthan with financial assistance from WASMO, along the same lines as what SACHETANA is attempting . These have strongly withstood the test of time and ALL of the rooftop rainwater tanks I saw (more than 120) were functioning and people were using this water exclusively for drinking and cooking. Here is a proof of concept idea which has withstood the test of time and which is ripe to be taken to areas of high fluoride and arsenic as one possible solution. Even in Gujarat this has unfortunately not happened in the fluoride affected areas at a scale which would benefit people.

A member of the PLC Watsan group Dhani behn, has built an Ecosan toilet for herself - one of the first in Gujarat-about a year back. This is one of the best toilets on Ecosan I have seen and the simple and elegant story of the same is hugely impressive. It is located in Bhavnagar Saurashtra - Gujarat. She was part of an exposure visit of PLC WatSan to a MYRADA project in Karnataka implementing ecosan. She has one simple reason for use of the toilet- it's less use of water. Even with a twin pit pour flush about 5 litres of water gets used for a single flush and in a day 20 to 25 litres of water can get flushed by one person. Even this is too much in arid and semi arid Gujarat. The transfer of knowledge has resulted in an elegant solution to an otherwise vexing issue that can be made applicable on a larger scale across the state. There exists tremendous interest in Eco-san from other parts of Gujarat too including the coast with its high and saline water table and the tribal hamlets with its hard rock terrain and the rest with a lot of water shortage.

"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.

Vishwanath calls on all to set aside the "yuck" factor and take a rational view of the use of urine as a fertilizer. From a open discussion he goes on to list out the advantages of using plant nutrient rich urine as fertilizer and provides the maths behind his validation!! Write in with your take in the comments!

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.
