The sophistication expressed in developing beautiful landscape all-around the campus of Pratishthan was going to be naught because of scarcity of water. The drought condition prevalent from 2000, compelled the search of additional source of water for maintaining the greenery of the campus. Most easily available source of water for the plants was the drainage water, which was going waste. In 2003, drainage water of the entire campus was connected through under ground pipeline to a constructed tank at the Nakshatra- Garden complex. Thereby, about 3 to 5 Lakhs liters of water is accumulated per day. A special filter has been installed on the tank to filter about 1 lakh liter water per day. The filtered water as well as the raw water(unfiltered) are used for maintaining the plants and lawn of the entire campus.
