Sewer rehabilitation – 1

Introduction Sewer rehabilitation encompasses many different aspects of civil engineering. This single term defines everything from the detection of a lost sewer to its final reconnection to an existing property after the renovation of the sewer is complete. In its broadest definition, rehabilitation can be split into two sections — the inspection and the renovation of the sewer. In the first part of this paper, the extent of the problem, the survey techniques employed and the initial remedial work needed will be discussed.
