In the title compound, C10H11NO4·H2O, the carboxyl group is twisted at a dihedral angle of 6.1 (3)° with respect to the benzene ring. In the crystal, the organic mol­ecules are linked by pairs of O—H⋯O hydrogen bonds involving both carboxyl groups, forming zigzag chains propagating along the b-axis direction. The water mol­ecules form [100] chains linked by O—H⋯O hydrogen bonds. The organic mol­ecule and water chains are cross-linked by N—H⋯Owater and Owater—H⋯O hydrogen bonds, generating (001) sheets.
