Le développement de l'assainissement par dépression : un réseau urbain retrouvé

Abstract : From the end of the 19th century to 1934, a few vacuum sewage collecting systems were tested in the Netherlands and in France. But it took more than 30 years before a new vacuum system was perfected in Sweden. It has taken another 10 years to reach adéquat development in France and to gain more acceptance by engineers and organizations concerned with the collection and disposal of sewage. The purpose of this research is to understand the development process of vacuum sewerage inovation in France, historicaly rejected and adopted nowadays. It is beyond question that the gravity sewer standardization process, started last century and achieved in 1949 with the diffusion of Caquot instruction, has doomed to failure the first collection sewer by means of barometric depression. Meanwhile, in recent years, it appeared that many situations could not be solved by either of the traditionnal options (septic tank / gravity sewer). The attemps to apply either technology in these situations have been unsatisfactory to all involved. Vacuum collection has thus emerged as a viable solution under economic and environmental constraints. Moreover, the vacuum sewer firms and adopter categories study show changes in all the sewer system organization.
