Hydraulic analisys of drinking water pipeline inter island

Abstract

One important study is the hydraulic study of water flow in the pipeline so that it can provide technical certainty that the water distributed to the destination island is in accordance with the plan to meet the drinking water needs of the island until the projected year between 15-30 years. This study used as a reference for selecting pipe specifications that are in accordance with the workload, so that the pipe is not damaged when the system is operated. Hydraulic analysis performed using Epanet 2.0 software with preferred output analysis is the flow velocity, pressure and capacity of water coming out of the pipe. In the hydraulic study of the underwater drinking water pipeline from Tidore Island to Maitara Island, the maximum pressure that works on the sea-based pipeline is obtained, the minimum speed up to the maximum water in the pipeline and the water capacity entering the Maitara island reservoir is 17.20 bar, 0. 4-2.26 L/s and 25.82 L/s. Considering the results of these calculations, the pipe specifications were selected with a 110 mm PN diameter High Dencity Polyethelin (HDPE) pipe with 20 lined three lane lines, with technical considerations of installation and operation and maintenance. The system, this pipeline can meet the drinking water needs of Maitara Island both domestic and non-domestic until the projected year of 2040 is 22.7 L/s.
