Abstract: This paper discusses the design of a tree-shaped water distribution system for small, dispersed rural communities. It revisits the topic that was discussed in the literature and is nowadays implemented in the field. It proposes a new approach to pipe selection based on robust optimization to account for the uncertainty inherent in intermittent demands. It also proposes a fast projected reduced Newton method of calculating stationary flows to test the performance of the networks thus designed by Monte-Carlo simulation. Numerical experiments conducted on real study cases have shown promising results both in terms of quality and performance of the generated robust solutions and in terms of computation time for simulations.
