Alexandria city has a large number of Hospitals which almost reaches 74 hospitals. All
Sanitary drainage companies are not aware of monitoring the quality of wastewater produced
from this kind of activity which is very hazardous in nature. In addition, all of the sanitary
wastewater drainage companies don't have specialized laboratories to analyze hospital
It severely affects the health of sanitary workers along the sewer lines and the pumping
stations and those working in the wastewater treatment plants and also on the quality of the
influent entering the treatment plants itself. This effect is more obvious for hospitals located
near these plants.
Nevertheless, most hospitals use the public sewer system in the disposal of some of their
hazardous solid waste. Therefore, it is important to manage hospital effluent quality to
minimize the impacts on the workers and the sewerage system.
Alexandria Sanitary Drainage Company was the unique company to establish a Management
system to monitor this kind of specific activity which included field survey for each hospital
to identify sources of hazardous pollution, sampling and analyzing the final effluent from
Alexandria hospitals, and provide technical assistant services to minimize the hazardous
pollutant effects of the hospital activities.
The most irritating problem was the high content of some hazard pollutants especially
phenols, which was found to be above the permitted levels of the Law 93 year 1962 and its
presidential Decree 44 for year 2000.
