Examining the technical, social, environmental, geographic, and economic features is necessary in the process of water and sewage projects on a large scale. The purpose of this research is to identify and rank water and sewage risks in Ilam province. In this research, using in-depth library studies to identify risk in the life cycle and using CVR content validity to remove irrelevant factors. Then, by designing a questionnaire and a statistical community of 40 water and sewage experts, which was determined using Cochran's formula, the effect of the importance of risk factors in the life cycle of the project was investigated. . In this research, the internal reliability of the structure is 0.76, which has established a good internal consistency, then using the Friedman test, the risks have been ranked, and in this research, the risks of lack of plans and executive details, lack of proper design, and the need The changes in the implementation phase compared to the plan have the most important risk and changes. Then, in order to prioritize the life cycle stages of the project, using the AHP technique and a community of experts (5 to 7 people), the life cycle stages have been examined with safety-cost-time alternatives, and the results show that design and planning have the highest priority and They have attributed the least importance to the establishment in this research.

Cement as one of the most important construction products has an essential role in the development of the country's development programs and is used in the basic sectors of construction, both as concrete and as concrete products and construction works. With the development of technology and increase The use of machine in the production ,hazards and accidents increases in such environments, and given that the protection of human health as the main factor of development, against various pollutants in the work environment of industries such as cement, measures and programs to It is important to ensure the safety and technical protection of workers and the protection of the environment in front ofenvironmental pollutant, which plays an important role in the supply and maintenance of manpower.In addition to providing the necessary safety to maintain manpower, since the cement industry is undoubtedly the main producer of dust and has a variety of it in different parts of the production line, production dust is a major environmental problem.
