Geospatial Approach to Water Supply Asset Management: Evidence from Damak Municipality, Nepal

Abstract

This study evaluates the Damak Water Supply System using a GIS-based asset management approach to map and analyze key water supply infrastructure. Field surveys, institutional data, and spatial mapping identified 16 borewells, 20 treatment plants, 3 overhead tanks, 16 pump stations, 172 valves, and 392 km of pipelines, serving 13,075 households over 19.73 sq. km. GIS analysis revealed uneven service distribution, with full coverage in Wards 1, 5, 6, 7, and 8, and limited access in Wards 3 and 10. Findings highlight the need for targeted upgrades and demonstrate GIS as an essential tool for efficient, equitable water supply management.
