Design Optimization of Water Distribution Suburban Area in Mranggen, Semarang, Indonesia

Abstract

Water losses in water distribution systems are one of the problems that occur in water distribution systems. Water losses can be caused by physical losses or leakage. Leakages can be caused by technical and non-technical factors. The existing condition of the water distribution network in subdistrict capital Mranggen, Demak Regency has not been able to drain water continuously for twenty-four hours in Batursari and Kebonbatur Sub-Districts. The optimization of the drinking water distribution network is carried out by evaluating the network system using Epanet software and then doing the rehabilitation design and network development according to future developments. The results of the analysis of the epanet model show that the use of deep well pump systems directly distributed to customers results in inefficiencies from pressure. Access to the safe drinking water needs to be prepared first from the availability of raw water, treatment units to the distribution network. The construction of clean water transmission pipeline system is prepared to go into different zoning from the initial network. Zoning pumping network systems will increase pressure significantly and reduce leakage through control.
