Abstract

SPAM of Palangka Raya City has a distribution unit which is powered by six pumps but only two pumps are functioning due to frequent damage to the pumps. The pumps that function is Pump III and Pump V. This research aims to evaluate pump efficiency and specific energy consumption (SEC) so that technical recommendations for optimizing existing distribution pumps are known. Pump III is installed with a VSD with a SEC value of 0.14 KWh/m3 with a pump efficiency of 70.41% so it does not require minor or major repairs but requires a new backup pump because it works 24 hours while Pump V has a SEC of 0.27 KWh/m3 with a pump efficiency of only 36.97% which requires a new pump replacement. Both pumps experienced the same problem, namely V-Unbalanced which reached 2.72-2.73%, causing a decrease in motor performance which could cause damage to the pump components and VSD, so a capacitor bank and voltage stabilizer were needed. The evaluation of energy loss in the distribution network was carried out by increasing the diameter of 57 pipe segments to reduce headloss to less than 10 m/km.

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.

Abstract

Non-compliant design of water treatment units can reduce process efficiency and product water quality. This study aims to evaluate the design conformity of the existing Water Treatment Plant (WTP) units operated by PERUMDA Air Minum Kota Palangka Raya against SNI 6774:2008 and established technical literature. The evaluation focused on the intake, coagulation, flocculation, sedimentation, filtration, and reservoir units using a retro-commissioning approach. Data collection included field measurements and review of technical documents. The results revealed several non-conformities, such as a GT value of 4.8×10⁴ (standard >10⁵), sedimentation detention time of less than 2 hours, and an overflow rate of 13.99 m³/m²/hour (standard limit 11 m³/m²/hour). These findings highlight the need for gradual technical design adjustments to enhance treatment efficiency.

Abstract

According to Regulation of the Ministry of Public Works and Housing of the Republic of Indonesia No. 27/PRT/M/2016, the maximum allowable level of non-revenue water (NRW) in a drinking water supply system (DWSS) is 20%. However, the NRW level of a regional water utility (Perumdam) in East Java has reached 26.47%, consisting of a total distributed water volume of 5,922,337 m³ and a billed water volume of 4,354,472.00 m³. One of the causes of this NRW is the distribution pipeline network system, which remains interconnected between different networks. This study aims to analyze the optimization of NRW reduction, particularly in one service zone. The research method used is an analysis of the existing conditions and NRW control using Epanet software. Based on the research findings, it was identified that all customers in the service zone met the minimum pressure requirement of 5–10 m. Water loss control was carried out through the establishment of a District Metered Area (DMA), optimization of the pipeline network, active leakage control, and pressure management. The results showed a reduction in physical water loss by 0.86%, with a saved water volume of 20,571 m³ per month.
