In the title compound, C(15)H(13)NO(4)center dot H(2)O, the organic molecule adopts a V-shaped conformation in which the dihedral angle between the five-membered rings is 68.33 (5)degrees. The cyclohexenone ring adopts an envelope conformation, with one of the methylene C atoms displaced by 0.607 (4) A from the plane through the other atoms. In the crystal, intermolecular N-H...(O,O) and O-H...O hydrogen bonds link the components into (001) sheeets and C-H...O interactions and aromatic pi-pi stacking [centroid-centroid separation = 3.6176 (19) A] help to consolidate the packing.
