Rehabilitation and Maintenance of Drains and Sewers (2nd edition) - Investigation

Investigation is the first of the four fundamental activities included in integral sewer management. To a reasonable extent, it is to cover all performance aspects of the drain and sewer system in order to create the basis for the next step (the evaluation of the capacity of the drain and sewer system). The obtained results serve to show compliance to due diligence, and also as the basis for the determination of all activities to be carried out with respect to rehabilitation and maintenance. That is why volume 4 of "Rehabilitation and Maintenance of Drains and Sewers" deals with the investigation and inspection.
