We show that any four-dimensional hyper-Hermitian manifold admitting a non-trivial triholomorphic Killing vector field is locally determined by the solution of a monopole-like equation on a three-dimensional Einstein-Weyl space of a special type. Conversely, any four-dimensional hyper-Hermitian mani
