This paper reviews the details of a sewer system, identifying the important aspects since any rehabilitation must be in conformance with the use and characteristics of the system. The discussion then reviews the general methods used to establish the condition of a sewer system and the need for repair. The paper closes with a review of the various methods currently used for rehabilitation of sewer systems and indicates the advantages of the use of such trenchless technologies.
