In the title compound, C14H16N2O4·H2O, three substituent groups are located on the same side of the benzimidazole ring plane. In the crystal, O-HO hydrogen bonds and - stacking between parallel imidazole rings [centroid-centroid distance = 3.858 (4) Å] link the molecules into a three-dimensional supramolecular structure.
