In this paper, we investigate the problem of optimising both the location and control settings of pressure reducing valves in multi-feed sectors in water supply networks. A simplification of the problem formulation is presented with respect to previously published research by reducing the degree of nonlinearity of optimisation constraints. The resulting optimisation problem is a nonconvex mixed integer nonlinear program. We then apply an outer approximation algorithm for the generation of good quality solutions of the considered design-for-control problem. We evaluate the presented method on a large-scale operational water supply network in the UK.
