Ecosan in Gujarat: Initiatives & users
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. Posted on 07 Apr, 2009 11:14 AM

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.
