Abstract: To be of any use to managers, infrastructure data must be compiled in a form they can use. The answer for the 1990s is a geographic information system that electronically combines data and maps for use in planning, design, maintenance and operations. In New York City, the current emphasis is on 6,000 mi of water mains. By 1995, when New York City's Water Main Mapping Project is complete, the water mains will have been entered into a geo-referenced digital database. The database is the fundamental building block for a geographic information system (GIS) that will include 180,000 valves, 99,000 fire hydrants plus appurtenances such as reducers, roundabouts and pressure-reducing valves. It will produce, on demand, a 1:360 (1 in. = 30 ft) or 1:1,800 (1 in. = 150 ft) water-main distribution map of any area within the city, a 322 sq mi area.
