Wastewater utility networks are complicated systems that must be managed carefully to maintain effective operation and environmental protection. This study proposed an integrated engineering framework that combines Geographical Information System (GIS), Closed Circuit Television (CCTV), and hydraulic modeling to improve wastewater network management. The framework addressed the disadvantages of using each method alone by combining their strengths. Geographical Information System (GIS) provides a spatial framework for organizing and analyzing data, while Closed Circuit Television (CCTV) and hydraulic modeling provide real-time information about the condition and performance of the network. The proposed approach can help to improve the efficiency and sustainability of the networks. The study was applied to the Zamalek region in Egypt, where Closed Circuit Television (CCTV) was used to recode 12,900 m, with a total of 21,500 m. It was found that there were cracks and fractures in some parts of the network that were filmed at a length of 6,450 m. The interior was treated and repaired by injection or lining for approximately 650 m, as well as changing 325 m by digging. The hydraulic study also showed the presence of some inverted branches, which required rehabilitation. A Geographic Information System (GIS) was used to provide integrated data on the region's network, such as the number of manholes (2600) and 5 expulsion lines, determining the locations of stations serving the region, and calculating the actual behavior of the network. This led to an increase in the design capabilities of the stations. The study also showed that the integrated engineering framework can be used to manage sewerage networks effectively.
