An Evaluation of the Efficiency of the Localize, Locate, and Pinpoint Strategy in Reducing Water Loss

Abstract

This study aimed to assess the efficiency of the Localize, Locate, and Pinpoint (LLP) strategy in curbing water loss within a water district. Employing a descriptive-comparative research design over seven days, the study utilized secondary data sourced from the water district office. This data, collected through noise loggers, electronic ground microphones, and other equipment associated with the LLP strategy, provided insights into the water loss reduction efforts. Before implementing the LLP strategy, the water district suffered from a high water loss exceeding 30%. Following the implementation, although the water loss remained high, it showed improvement, indicating that other factors might contribute to the loss. The results demonstrated a significant disparity in water loss before and after implementing the LLP strategy, suggesting that while complete elimination of losses may not be feasible, the strategy aids in substantial reduction. The study revealed that the noise levels, used as an indicator of potential leaks, exhibited a moderate confidence level before the implementation of the strategy. Conversely, after the LLP strategy adoption, the confidence level dropped to a low, indicating a decreased likelihood of leaks. Moreover, statistical analysis confirmed a noteworthy difference in noise levels before and after the implementation, lending support to the efficacy of the LLP strategy. Furthermore, this study underscores the positive impact of the Localize, Locate, and Pinpoint strategy on water loss reduction, despite not achieving complete elimination. The findings underscore the strategy's efficiency in identifying and minimizing potential leakages, thereby contributing to the reduction of non-revenue water within the water district.
