MODERN METHODS OF STREET CLEANING 



The cause of the epidemic of 1892 was polluted drink- 

 ing-water taken from the river Elbe. 



After years of investigation, a filter plant to purify 

 the Elbe water was completed in 1893. Subsequently, 

 other notable improvements were made in the water- 

 supply, including the removal of the intake to a safer 

 location. At the present moment, the city is develop- 

 ing a supply of drinking-water from wells. 



The sewage of Hamburg is collected into a large 

 tunnel or subterranean reservoir and, after careful 

 screening, discharged into the Elbe on the outgoing 

 tide. 



At the time of the epidemic of 1892 a number of 

 sanitary experts were called to Hamburg to help fight 

 The Hygienic the epidemic and among them an American, 

 Dr. Dunbar. When the epidemic was over, 

 Dr. Dunbar remained in charge of a municipal sanitary 

 institute which the city had established. This was soon 

 raised to a position of great importance. The work 

 done by Dr. Dunbar and his assistants in helping to 

 regulate the sanitary condition of the city has been of 

 value in many directions. Not only has expert atten- 

 tion been given to cholera, plague, and other diseases 

 to which the immense shipping exposes the city, but 

 other important studies have been carried on. In no 

 other city in Europe is the danger of epidemic disease 

 so great and so capably guarded against.
