China is a country with very limited water resources in terms of its large population. In the 21st century, the problem of water shortage will become even more serious with increasing population growth and social development. Wastewater treatment, therefore, becomes a most important issue.In the past decade, wastewater treatment has been developing at a fast speed. However, at present, the government couldn't invest much money in the wastewater industry as in the past. Therefore, there is a big gap for capital investment for the building and operation of WWTP (wastewater treatment plants). Under the circumstances, BOT comes out as good solution. However, little research has been conducted on the theories and practices of wastewater treatment plant BOT project control in China. Therefore, in-depth research on the theories and practices has become an urgent issue in wastewater development.The researcher first introduced the general situation about wastewater industries in China. The theories in current practice are mainly CPM (Critical Path Method) and PERT (Program Evaluation & Review Techniques). Problems of applying these theories in practice of WWTP were noted and analyzed. Delaying of project accomplishment, for example, is caused because a number of unknown factors affecting the project are not under control. A new theory, therefore, was proposed to replace the two theories-- CCPM (Critical Chain project management). The new theory is based on TOC (Theory of Constraints). By using project buffer, feeding buffer, and resource buffer, and setting up precaution mechanism, CCPM manages to control these unknown factors which the former two theories, CPM and PERT, fail to monitor. Therefore, the application of CCPM leads to WWTP project success. The researcher took the wastewater project of Lingang New City, Shanghai, for example, analyzed the reasons of its failure in using CPM on its project management, and went further to propose that the new application of CCPM may lead to its success. Detailed analysis was provided.The research, though with much deficiency due to limited time and resources of the researcher, is supposed to provide some useful guidance for future wastewater BOT projects in China.
