KAJIAN KEHILANGAN AIR PERUMDA DELTA TIRTA PADA DMA SHOJI LAND CABANG PORONG

Abstract

The maximum allowable water loss, as defined by the Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat Republik Indonesia No 27/PRT/M/2016, is 20%. However, the Delta Tirta Regional Public Company has exceeded this limit, with a water loss of 32%. A study was conducted on the Shoji Land Porong Branch District Meter Area (DMA) in July 2023, which revealed a water loss of 56%. The objective of this study is to quantify the financial losses attributable to water loss and to propose improvement solutions based on an analysis of the underlying causes of water loss, as reflected in the water balance. The results of the study indicated that the percentage of water loss in October was 51%, with a percentage of physical water loss of 31.4% and 19.4% for non-physical water loss. The mean financial loss resulting from water loss between August and October was Rp. 31,897,659 per month. Consequently, a design based on the causes of water loss namely, water leakage, inaccuracy in the zoning meter, and inaccuracy in the house connection meteris imperative. To address this issue, a strategy of replacing and resetting water meters, as well as pipe repair, was implemented based on the October water balance data.
