Abstract: This study evaluates use of vegetation filter for pollutant load removal from grey water, generated from GBPUAT, Pantnagar, India. Grey water is rich in nutrients and organic load and was used for fertigation of woody crops of Eucalyptus hybrid, Populus deltoides, Salix alba and Melia azedarach. Average reduction of N, P and K was 50, 34 and 15%, respectively. Reduction in BOD and COD were 60% and 46% respectively with residual BOD < 30 mg/l. Dry biomass yield of woody crops under wastewater irrigation in comparison to control (ground water) was: Eucalyptus hybrid, 143; P. deltoides, 54; S. alba, 274; and M. azedarach, 321%. Nutritive value of M. azedarach leaves as a fodder was found good.
