The headquarters of the Brahma Kumaris in Mount Abu, Rajasthan, welcomes around 300,000 visitors every year to its 3 campuses, the largest of which is Shantivan situated in Abu Road. Thirty two thousand people can be accommodated at any one time and they often stay for 3 to 4 days in order to attend spiritual retreats, conferences and workshops, including ones to raise environmental awareness. The water requirements are therefore massive and include providing cold water for drinking and cooking, water for bathing, water for the Hospital and water for gardening.
For conserving rainwater Brahma Kumaris has built reservoirs at its headquarters campuses and in the nearby places of Abu Road. Besides this, all the major center buildings of India have proper underground water harvesting units.
