摘要

The 1976-77 drought inspired a variety of efforts to ration the limited water supply. The three most common in Utah were found from a survey of 33 municipal water supply systems to be (1) restrictions on times when outside use is permitted, (2) price increases, and (3) upper limits to allowable monthly water use. A regression model applied to use data for these communities showed that mandatory water use regulations proved much more effective than price increases in reducing water use. A theoretical analysis of the demand and supply functions showed the current pricing schedule to be about optimal. A third model showed that there were substantial economic losses, largely in the form of reduced consumer surplus for residential users, associated with the 1977 regulations. The third model analyzed various management policies in terms of their impact on net benefits to the agricultural and municipal sectors. The model revises water allocations monthly, to match a changing hydrologic situation.
