Population growth in the city of Surabaya encourages local water supply companies PDAM (Perusahaan Daerah Air Minum) Surya Sembada to maintain the desired level of service regarding asset management needs. PDAM already has a meter recording application for record positions and water usage for asset inventory using smartphone internal GNSS and Geodetic GNSS but has low position accuracy. The application is less effective because time-consuming and a long process, so integrate customer data with land and building taxes data as the basis for determining tariffs, it isn't easy to do. These limitations have prompted this research to develop a more effective, cost-effective asset mapping system with more accurate positioning. This study develops an asset management system in android smartphone that uses low-cost GNSS then integrated with WebGIS (Web-based geographic information systems) for mapping and managing PDAM water meter assets. Android applications and WebGIS are connected through a database that uses an API (Application Programming Interface) to communicate between platforms. The low-cost GNSS accuracy showed very good results compared to the Geodetic GNSS. Sub-zone 102, which has customers such as large industries, warehouses, offices, large businesses, and public service offices, shows a very high-risk analysis of asset damage.
