Use of waste water in ...

Use of waste water in agriculture has been practiced in our city Indore in M.P. more than 60 years back. The waste water was flowing through the River Khan the main drainage of the city of Indore and was lifted and treated up to primary level and latter was sent to the fields. This was accomplished by the Indore Municipal Corporation. This water contained industrial as well as the domestic waste. Many years latter the system gradually became useless and the farmers themselves started pumping water from the open drain and started irrigating the fields. The system is still continuing and it appears that the soil and the crops in fields are unaffected. Recently the Indore Municipal corporation has started a UASB based treatment plant but still the farmers are continuing with the pumping. Recently in various institutes viz the Indian Institute of management, Indore, The Choithram Hospital Indore and Shre G.S. Institute of technology and Science etc. bio-filter based treatment plants have been installed and the need of secondary and tertiary uses of water such as gardening, toilet flushing etc. has been initiated to be fulfilled by the recycled waste water. This is functioning very well and there is an advantage in terms of ground water enhancement.
