Abstract

A water distribution pipeline network is a system that transports water from points of supply to points of demand where water must be delivered at a certain rate and pressure head. The system consists of water supply points, water demand points and pumping stations all connected by pipelines according to some network geometry. In this paper we consider the one-period deterministic design problem of a water distribution pipeline network. The design problem in water networks with no loops (tree networks) and in water networks with loops, respectively, is mathematically formulated with pipe costs, pump costs and energy costs being minimized. Efficient solution methods exploiting the network structure of the problem are developed for tree networks. In the case of networks with loops, two distinct design objectives are considered. One involves only the hydraulic requirements of the network and the other involves the hydraulic requirements and a reliability requirement in the network. For the first design objective, it is shown that the optimal solution of the problem can be obtained by solving the design problem on a spanning tree of the network. In the second situation, a proper formulation of the problem is presented and its complexity is discussed.
