Postattack Sanitation, Waste Disposal, Pest and Vector Control and the Effects of Fallout in Waste Water and Sewer Systems

摘要

The study presents information on the magnitude, character, and timing of postattack sanitation operations for the San Jose Metropolitan Area of California and assesses the effectiveness of these overall operations on maintaining disease incidence at levels which will not be detrimental to postattack recovery. It also presents information on the sedimentary effects of fallout washed into drainage systems including: (1) a method to determine the effects; and (2) the sections of the systems which are most likely to experience sediment build-up. The results of the analysis of the postattack sanitation operations in the Study Area indicate approximately 60 percent of the waste collection vehicles will be damaged, but due to increased use of the surviving vehicles and the postattack reduction of household refuse production, no detrimental effect on the overall postattack recovery of the area is expected. The study of fallout transport in drainage systems indicates that sediment build-up will occur when the flow rate per unit of width is decreased, as in the case of water exiting from a catch basin connector pipe into a main line.
