Status of Utilization of Hydraulic Ram Pump
Downloads
The study assessed the current status of hydraulic ram pump utilization in the Philippines. This developed a georeferenced map showing the location of established hydraulic ram pump installations and described the spatial patterns of ram pump installations. A systematic review and meta-analysis approach guided by PRISMA 2020 standards was employed to collect and synthesize data from peer-reviewed publications, institutional reports, and online sources. Web-based data collection and geocoding techniques were used to determine installation locations, which were then analysed through geospatial and artificial intelligence–assisted interpretation. A total of ninety-three (93) hydraulic ram pump installations were identified nationwide. Results revealed that adoption is unevenly distributed and concentrated primarily in regions with favourable topography, watershed availability, and rural water demand. Regions with mountainous and upland characteristics exhibited higher utilization, while highly urbanized areas and regions with institutional and infrastructural constraints showed minimal or no installations.
