| Correspondent: Man's sewerage practice has been known from ancient times. Dr Smith, can you briefly outline its progress? Professor:O.K., You see, explorations revealed sewers in Babylon dating from the 7th century B.C. Considerable information is available about the sewers of Jerusalem, works of this class in ancient Greek cities are fairly well known and the great underground drains have repeatedly been described. Correspondent: Hmm. And what about this country, London to be exact? Professor:The history of the progress of sanitation in London probably affords a typical picture of what took place quite generally about the middle of the 19th century in the largest cities of Great Britain. Correspondent: Yeah, but how did it look like? Professor:Well, first of all, it was the lack of central authority rendered a systematic study and execution of sewerage work impossible. As late as 1845 there was no survey of the metropolis adequate as a basis for planning sewers. The sewers in adjoining parishes were of different evaluation so that a junction was impracticable. One of the drawbacks of London sewerage system was that some of the sewers were higher than the cesspools which they were supposed to drain while others had been so constructed that to be of any use the sewage would have had to blow uphill. Large sewers were made to discharge into small sewers. Correspondent:But did anyone study and solve the problems? Professor: The first engineer to make a comprehensive study of metropolitan sewerage needs was John Phillips. He described the conditions of London cellars and cesspools, and offered the scheme of the drainage. After two outbreaks of cholera a royal commission was appointed to inquire into sanitary improvements of London. Than Parliament passed an act for the better local management of the metropolis which laid the basis for the sanitation of London. |
