Abstract: Cisadane River is an important river of Banten Province Java Island Indonesia. Cisadane River water is used for irrigation, industry and municapal supply. However, there are fundamental problems in the river, which is the low quality of the water. The government has been any treatment through several projects, including the normalization of rivers, construction of embankments, parks, and other facilities.The approach of these projects has yet exerted great influence in the management of river water quality, because of the high pollution of the river water.

In the project construction implementation have a big enough risk that can lead to the management of water quality is not good.For the risks that may arise need to be analyzed in order to project and infrastructure assets can function as planned.The process of analyzing possible risks may use a risk management approach. This research aims to identify risk on projects that have been carried out in the handling of Cisadane River, analysis of significant risks, and determine the type of response to significant risks.

The research process is done by conducting a survey. The series begins with the identification of risk analysis through the study of literature, after it carried out a risk analysis performed by assessing risks on the project - a project that has been built before.The risk analysis is done by estimating the likelihood that the biggest risk will occur and the resulting impact.  

Based on the analysis results will be known which variables significant risks in project implementation and management are of project assets. So expect this study could provide a significant response in river water quality management through project approach that has been awakened.

Key word: quality water, risk management, project approach, risk responses
