  • Washington State Department of Health Environmental Public Health DivisionOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Extreme Reality New Orleans August 31: Two days after landfall With the storm over and the hospital functions leveling off, it was felt that the worst was over. Then, the citys water pumps ceased functioning. The problem with lack of city water was not that of hand cleaning or having enough drinking water, but rather that the hospitals air conditioning system would not function. The system uses 150,000 gallons of water per day to cool the chillers. There was an option to use Mississippi water to cool the chillers, but the impure water would soon clog the system. At this point, Mr. Worley met with his staff, and the decision was made to evacuate Childrens Hospital New Orleans.
