The two independent CdII atoms in the polymeric title compound, [Cd(C10H8N2)(H2O)4](C7H4O6S)·H2O, lie on twofold rotation axes, and each is coordinated by four water molecules and the N atoms of two 4,4′-bipyridine molecules in an octahedral geometry. Bridging gives rise to chains along [101] and [-101]. The 4-hydroxy-3-sulfonatobenzoate dianions are not connected to the CdII atoms, but form hydrogen bonds to the coordinated water molecules as well as the lattice water molecule, generating a three-dimensional network.
