Water availability for agriculture in the country is projected to go down to around 70 per cent by 2025 which undoubtedly will limit the country’s capacity to provide expected food security. Under this water crisis scenario, grey water - an alternate source to supplement the overall water use is the need of hour. Characterization of grey water with special reference to key water quality parameters signifies immense importance for further reutilization so far the water productivity is concerned. A study was conducted at Assam Agricultural University on characterization of grey water in order to assess its feasibility to reuse, where grey water was collected during the month of February, 2017 from 10 different sites within the campus, viz. Hostel 1, Hostel 2, Hostel 3, Hostel 4, Hostel 10, Hostel 11, Hostel 12, Hostel 14, New Professors’ Colony and International Girls’ hostel to observe 14 key quality parameters. Variations of total N were found to confine below the ideal value ( 1.5 (µg/ml) observed in Hostel 2, Hostel 3 and Hostel 12. Arsenic in grey water with a mean value of 30.43 µg/l varied from 13 to 53 µg/l was found to exceed the threshold level (> 10 µg/l) recommended by WHO.
