Abstract

NRW is still a problem for PDAMs in Indonesia in providing drinking water for the community. This can be seen from the national average NRW level in 2021, which was 33.72% (higher than the RPJMN target of 30%). The ATR reduction strategy can be carried out correctly if the indicators or components are accurately measured. The problem is that many PDAMs need help to understand the definition or calculate ATR components according to international standards with high confidence. In this research, a water balance was prepared using WB-EasyCalc to determine the value of each ATR component with a 95% confidence level, potential loss of income, and ILI value. The results of the water balance analysis show that the ATR level at Perumda Air Minum Palangka Raya in May 2023 was 51.84%. This percentage comprises 2.19% non-revenue official consumption and 49.64% water loss. If the NRW percentage is not reduced, the potential loss of income is estimated at IDR 15,395,984,969/year. The component that causes the most water loss is physical water loss, which reaches 42.67%. The physical water loss performance indicator (ILI) has a value of 23, which is included in performance category D (extraordinary waste of resources occurs, and leak reduction programs must be prioritized). Recommendations that can be given are related to the active leak detection and pressure management.

Abstract

Access to clean water is the right of every citizen that the government must fulfill, both the central government and local governments, through drinking water business entities, namely PDAM. The performance of a PDAM represents the quality level of drinking water administration in an area. Only now, the high loss of drinking water has become problematic for PDAMs in improving their performance. One of the PDAMs with a high loss of drinking water is PDAM Tirta Yapono, Ambon City, with a water loss rate of 69.85%. In this paper, an effort is made to reduce water loss in PDAM Tirta Yapono by establishing a DMA in the Wainitu Village based on the existing condition of the pipeline, along with the number of sensors and instrumentation needed. SCADA and asset management implementation are also designed to support DMA's performance in reducing water loss. SCADA's role in reducing water loss facilitates the implementation of step tests and automation of monitoring activities for the distribution process and water quality by placing several instruments in the distribution network. Monitoring with SCADA will provide accurate data. Then, asset management also plays a role in reducing water losses because the information contained in asset management is used as material for preparing a strategy to reduce water losses following the priorities and capabilities of PDAM Tirta Yapono.
