Abstract
Non-Revenue Water (NRW) remains a major inefficiency in urban water distribution systems, representing water losses from leaks, illegal connections, and metering inaccuracies. This study employed a quantitative descriptive research design to evaluate the effectiveness of maintenance practices in reducing NRW in PrimeWater Cabanatuan City operations. The study analyzed NRW performance data, maintenance records, and environmental indicators derived from operational inputs. Results showed that NRW decreased from approximately 40% to 28% following the implementation of maintenance interventions such as leak detection technology, pipeline rehabilitation, and digital asset monitoring systems. Descriptive analysis indicated an average NRW reduction of 12%, with some areas achieving reductions of up to 25%. Environmental indicator analysis based on operational data revealed improved resource efficiency, particularly in reduced water losses per maintenance cycle. The study concludes that structured maintenance practices significantly contribute to NRW reduction and improved system efficiency. Strengthening infrastructure rehabilitation and digital monitoring systems is essential to achieving sustainable water management targets.
