Water supply projects (WSP) requires high plan information, specialized capabilities, capable human resources, and high administrative capacity. However, in the developing countries, particularly in Iraq, these projects experience a lack of a large number of these necessities, which shows the need to identify the critical success factors (CSFs). Accordingly, the objectives of this research are to investigate the CSFs for WSP and their significance among the construction (public and private) and education sectors. To achieve this, first we have carried out a comprehensive literature review of the CSFs for WSP. Second, we administrated a questionnaire survey to 260 construction experts working in the construction and education sectors. It was found that the top five important success factors for water supply projects in Iraq were a stable political environment; sustainable construction legislation and regulation; effective risk management practices; well-organized and committed project teams; and government decisions through the project life cycle. The survey results did not indicate major differences in the perception of the experts. The findings are focused to assist construction practitioners’ gain better understanding on the important areas to achieve project set objectives.

Working locally acting Globally is the essential principle in the modern world, to achieve this principle all the countries should work together to protect the Natural environment and the ecosystem. The protection methods and procedures were developed and adapted to suit all fields of the life specially the industry fields, Green Management (GM) considered one of the important methods for this purpose because it provides the bases for environmental conservation. Industry of construction shares a high percentage of the world economy as well as adverse influence on the environment as natural. The current paper tries to set the challenges and benefits of adopting the GM in Iraqi industry of construction throughout exploring the important Factors (main and sub-Factors) that affect the applications of the GM as well as the motivation factors. To achieve this goal a review of literatures was performed to collect the effecting factors, then these Factors were evaluated by the experts using questionnaire survey and the questionnaire results were analyzed utilizing Process of Analytical Hierarchy (AHP). The results revealed that the main factors are the financial factors and the Project-related and technical factors with 23% and 19% of important respectively. Accordingly, the conclusions were extracted with a set of recommendations which mainly state the important role of the Iraqi government in the application of GM in the industry of construction.
