In the title compound, C(14)H(20)N(2)O(3)·H(2)O, the geometry about the morpholine N atom implies sp(3) hybridization. In the crystal, symmetry-related mol-ecules are linked by inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, forming infinite chains along the b axis. The chain structure is further stabilized by intra-molecular C-H⋯O inter-actions.
