Consideration is given to the lower level of a hierarchical optimization structure for evaluating optimized control schedules for common types of water distribution systems. The structure is presented in Part I. The lower‐level optimization problem involves independent optimization of a number of generalized pump stations. This requires minimization of individual pump station consumed power. An algorithm for the pump station power minimization is proposed and its convergence and optimality properties are investigated. The algorithm is tested over a range of physical data. Typical results are presented, which include comparisons with an alternative solution method.
