In the title compound, C15H15N3O3·H2O, the hydazide Schiff base mol­ecule shows an E conformation around the C=N bond. An intra­molecular O—H⋯N hydrogen bond makes an S(6) ring motif. The dihedral angle between the substituted phenyl rings is 23.40 (11)°. The water mol­ecule mediates linking of neighbouring mol­ecules through O—H⋯(O,O) hydrogen bonds into infinite chains along the a axis, which are further connected together through N—H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001). C—H⋯O inter­actions aso occur.
