Inspection Requirements of Wastewater Collection and Conveyance Networks

Proper asset management of wastewater networks requires complete understanding of the set of facilities that are involved in the utilization of wastewater collection and conveyance networks and their treatment. A large part of the recognition of sewage networks is achieved through a series of sewage inspection procedures and, in most of the inspections, cleaning the network before the survey is mandatory. The importance of the role of sewage inspection as the first step in the asset management of wastewater treatment facilities is undeniable. The realization of the objectives of the inspection of wastewater networks is subject to cases where, in the absence of attention to it, inspections remain unrealistic and the realization of the objectives of the relevant projects is impossible. In order to fulfill the objectives of the inspection projects, firstly, the scope of the work must be precisely determined. Secondly, depending on the nature of the inspection work, the appropriate template for assignment of the work is selected in such a way that all aspects of the operation and execution of the work and the technical and legal requirements for projects cover the inspection. Aim of this paper is to study the initial challenges in realizing the objectives of the inspection and rehabilitation of sewage networks, while examining the experience gained in the country, the basic requirements of the projects mentioned, and the need for more attention of activists and researchers in the field of water and wastewater emphasize the essential elements of inspection and recovery of wastewater networks.
