Washington Metropolitan Area Water Supply Study. Volume 5. Annex D, Volume 1. Effects of Water Supply Deficits.

摘要

This Annex defines and assesses the socioeconomic, physical, aesthetic, and other miscellaneous short-term effects of water supply deficits of 10, 20, and 30 percent in the Metropolitan Washington Area (MWA). A methodology to determine losses in the MWA for actual and potential water shortage conditions is developed. The Annex is also intended to serve as a planning guide for the various water suppliers in the MWA, not only for estimating requirements on future water supplies, but in allocating short supplies during emergency conditions. The four major areas of emphasis in the Annex are: (1) evaluation of the Metropolitan Washington Council of Governments (MWCOG) Emergency Plan, (2) determination of the effects of deficits on water supply systems, (3) estimation of the economic impact of water supply deficits, and (4) a description of social impacts. Projections indicate a 2-week survival of MWA without serious economic damage for a water supply deficit of up to 30 percent, especially in the tourist industry, commercial enterprises and light industries which use large quantities of water. People who have the least mobility and resources are found to suffer the greatest social impacts from large deficits. Also indicated are interconnections among water supply systems and uniform standby ordinances on restriction of commercial and outside water use. (Author)
