Switching of water supply in regional general company Tirta Moedal drinking water, Semarang City, West Semarang branch

Abstract

The Semarang City Government, through the Tirta Moedal Regional Drinking Water Company (PDAM) Semarang City, plans to improve clean water services in the West Semarang Region by increasing production capacity by building a Water Treatment Plant (WTP) in Bambankerep Jatibarang with a capacity of 1000 liters/second for West Semarang area services. For the Jatibarang WTP to be absorbed according to schedule, it is necessary to divert the existing water supply to other service areas that need and are not included in the Jatibarang WTP service area. This study aims to comprehensively study the most likely directions for transferring water supplies to areas that currently require additional supply with the transfer system. The research method uses hydraulic analysis of the piping network using the Epanet 2.0 program. The analysis results will be displayed in pipe diameter, flow velocity and pressure at each junction point. The results obtained are the diversion of the existing water supply to another area outside of Jatibarang WTP. The result to be achieved from this research is an increase in the capacity and service coverage of Tirta Moedal Regional Drinking Water Company in the North Branch.
