LA DEGRADATION ET LA REHABILITATION DES RESEAUX D'ASSAINISSEMENT FRANCE - ANGLETERRE - ETATS-UNIS

Abstract : Sanitary sewers in England, in the U.S.A. and in France are currently undergoing serious degradation. The outword symptoms degradation vary in each of the countries. The symptoms consist of structural failure, poor performance and low efficiency of collection's systems. However, in evaluations
sewer system performance we must look beyond physical and technical symptoms. In fact the real capacity of many sewers systems, in the three counties, is no longer compatible with the quality requirements and objectives of the groups in charge of sewer systems. The environment in which sewer systems are planned and managed in the three countries has changed significantly over the past few years, and water quality goals and system objectives have been raised. Consequently there has been an
increase in sewer systems failures. Previous maintanance methods and types of allowable uses have become incompatible with the new requirements and objectives of the service.
Rehabilitation is one of the solutions to the increase in the rate of sewer system failures. It consists of transformation in physical structure of sewers (e.g. the use of several different materials) and an increase in system complexity. These physical transformations lead to changes in organisations providing sewer system services. Indeed rehabilitation allows these organisations to adjust to changes in the physical ans social environment.
