Kajian Kehilangan Air pada Perencanaan District Meter Area PDAM Kota Pasuruan

Abstract

Water loss that occurred in the service area of the Pleret 1 Reservoir managed by PDAM Pasuruan City from January to November was 42.92%. The highest water loss occurred in January of 46.85% and the lowest in May of 33.43%. This is still very far from the standard 20%. The current condition of the Pasuruan City PDAM distribution pipeline network is that all systems are connected to each other, so that there are no separate systems. Efforts that can be made by PDAM Kota Pasuruan to reduce water loss and interconnection networks are to isolate the piping network by establishing a DMA (District Area Meter). Formation of DMA requires hydrolysis modeling simulation of distribution pipeline network using Epanet 2.2 software. Besides using Epanet 2.2 software, Quantum GIS 3.16.16 software is needed to create a pipeline. The validity test in the field uses the discharge parameter with a correlation coefficient between EPANET and field discharge data obtained at 0.61. The formation of DMA with good results to reduce air loss is by reducing air pressure, if the air pressure decreases, the air loss will be lower.
