Sequencing the expansion of water supply projects to minimize discounted operating and capital costs can be formulated graphically as finding a least cost path from the present to the fully expanded future. In light of this model a simple dynamic programing algorithm or minimal cost network algorithm can be readily used in conjunction with a computer to solve the problem.
