Introduction and Problem Statement
Sustainable United States fresh water supplies have generally stagnated relative to the burgeoning demand from residential, industrial, agricultural, and commercial sources. As the presence of fresh water is necessary for most human development, whether for drinking water, irrigation or industrial usage, it is imperative that the United States develop a plan to meet this challenge in order to ensure its continued capacity to develop as a nation. We seek to develop a comprehensive policy plan to present to the United States Congress to manage the growth of water supply and demand over the period until 2025 according to four significant criteria. First, this plan must supply all projected water needs in every area and allow for variations in water supply. Second, it must not assume the existence of technology that is materially superior to present-day technology, either in function or in cost-efficiency. Third, the plan must not require decreases in water demand due to conservation which cannot be explicitly actualized through empirical statistics and robust public policy. Fourth, it must not result in inflation-adjusted per capita water supply costs of more than twice present values. Fifth, it must not result in cumulative inflation-adjusted capital investment of upwards of $2 trillion (feasibility). To quantify the effects of our plan, we seek to design a computerized model which would represent the cost of transporting fresh water from significant sources of fresh water within a given region to regional processing centers and the cost of transporting this processed fresh water from the processing center to agricultural, industrial, and residential water usage areas within the region. Further, we sought to model the effect of inter-regional water transport and storage procedures, in addition to the fixed costs associated with the maintenance of water transportation methods, e.g. pipelines. Finally, we sought to model the effect of concerted conservation initiatives, balancing this against feasibility concerns and the desalination that it offsets.
