It is not efficient or economical for metropolitan water providers to purchase small amounts of water and then transport that water to the south. Economies of scale discourage such patchwork purchases where options to make a single purchase of a larger quantity of water exist. The Aurora purchase is for shares with an already quantified historic consumptive use of 1,629 acre feet for a purchase price of more than twenty-six million dollars. The shares historically irrigated approximately 1,100 acres.
Small purchases are unrealistic to meet the growing Denver metro area needs. There are not many large blocks of water available for purchase by Denver metro water providers. This purchase does not necessarily represent a trend, but rather Denver metro water providers securing water for current needs and future growth.
