Abstract

Sewage pipeline projects in Iraq are typically implemented using the open-cut method along public roads. This approach presents numerous risks that adversely affect the daily lives of residents in the construction areas. This study evaluates the negative impacts of sewage pipeline network construction based on prior research concerning the affected population. Confirmatory factor analysis, including both first- and second-order factors, was conducted on data collected from 100 individuals within the study area. Five research hypotheses were tested and confirmed, revealing that traffic, welfare, environmental, economic, and safety factors significantly disrupt the daily activities of the local populace. The study's findings indicate that welfare-related risks contribute to 92% of the observed adverse effects, economic risks account for 88%, and safety-related risks for 86%. In contrast, environmental risks had a comparatively lower impact, influencing only 45% of the variations in adverse effects. Among welfare services, water, electricity, and internet networks were the most affected due to excavation-related disruptions. The study advocates for adopting trenchless piping technology to minimize disturbances to essential services, roadways, the environment, and the economic activities of residents during sewage pipeline construction.
