U Urban growth and industrial development have a considerable impact on the hydrological cycle which makes it a large influence on the urban drainage. Therefore every city development must be followed by an improvement in the drainage system, not only in the developed location, but also in the surrounding area. Thus it is necessary to identify and assess the risk in order to reduce or minimize existed risks hence the occurred losses are still within the accepted limits. Risks which had been reviewed were the risk of implementation, the risk of environmental and natural damage, the risk of resource, the risk of financial, and the risk of political and legal. The data collection was carried out by distributing research questionnaires to three contractors of the channel normalization project implementation in West Jakarta, with 60 questionnaires. The data processing was done using the method of Index Mean RRI, and was assisted by the SPSS Statistic v25 software. The analysis results showed that there was one of the highest significant risk variables, which was the obstacle in the implementation, due to the network utility that was embedded in the bottom of the channel.
