OPTIMIZATION OF CLEAN WATER DISTRIBUTION SYSTEM USING EPANET 2.00.12 SOFTWARE (CASE STUDY: JABABEKA INDUSTRIAL ESTATE 1, BEKASI DISTRICT, WEST JAVA)

Abstract

Clean water is a necessity in all aspect of life. One sector that really needs clean water is the industrial sector. Industrial sector is the one of sectors that play a role in the development area. Jababeka Industrial Estate (JIE) 1 is located in North Cikarang, Bekasi District, West Java. They have to 942 customers. Objectives: The aims of this final project are to improve the water distribution network design of JIE 1 in EPANET 2.00.12; to analyze the water distribution network based on Public Works Department 2007 and JIE Regulation; and to give the analysis result that can be used as recommendation for JIE 1. Method and Results: The method that been used are data collection, data processing, and data analysis. Primary data is obtained from survey, meanwhile secondary data is obtained from Jababeka. Data Processing is using Ms. Excel to calculate (1) the average of water consumption, (2) the flow and pressure of pump, (3) the water fluctuation, and (4) the water multiplier factor. Data analyzed by using EPANET 2.00.12 software, inputting the water demand, network map, pipe characteristics, and water fluctuation for 24 hours. Conclusions: The water distribution network in JIE 1 has been updated. It was proven by water distribution network that in accordance with the number of customers in 2019; The pressure in the existing of JIE 1 water distribution network have been complied with the two regulations. Where the pressure is range 10 m – 80 m. Some of the velocity is below the standard; Changing pressure in distribution pump from 37.7 m to 32.5 m will give the potential economic saving Rp. 182,742,637/year. Recommendations: Do the research about the others hydraulic parameter (excluding: pressure and velocity) in JIE 1 water distribution network based on Public Works Regulation; It is needed to research about the influence of changing pressure to the water velocity in JIE 1 water distribution network; It is required to research about pipe leakage in JIE 1.
