The difficulty of clean water in Indonesia, especially areas far from the city, resulted in a shortage of drinking water supply for the surrounding communities. CV Ulu Ulu Utomo company engaged in the trade and installation of deep water well pumps for irrigation and industry in the work of the project so far has not used the method of scheduling the project in planning the time and cost required, so there is still a delay in work time and additional costs. Therefore, this study aims to determine the form of network diagram, analyze the optimal time, and estimated total cost of deep well pump construction project in Sorong, West Papua using Critical Path Method (CPM). This research is a type of descriptive and accurate research that systematically describes project activities and data sources obtained from interviews, observations, and documentation. The results of research with Critical Path Method (CPM) showed a network diagram on a series of project activities that are on a critical path is the A1-A2-C2-C4-D2-E2 trajectory with a normal time of project completion for 102 days and a cost of IDR 79.353.000 while the project completion time is accelerated to 91 days over 6 hours at a cost of IDR 82.593.890.
