Abstract
Leveraging Legacy Maintenance Data and GIS to Optimize Infrastructure Replacement and Rehabilitation
Track: Water Distribution, Wastewater, and Stormwater
Author(s): Marcia Tucker, Amymarie Corriveau
The Washington Suburban Sanitary Commission (WSSC) has been tasked with an aggressive program for the replacement of aging water mains in a two-county region of Maryland. Beginning in fiscal year 2002, eight miles of water mains will be replaced. While this represents a 30 percent increase in the amount of mains replaced, it can only address less than 0.1 percent of the overall system. For this reason, the WSSC must be able to quickly analyze a large amount of information on pipe conditions, work histories, and geographic location to direct the replacement work to the highest priority needs. Making these decisions requires a much more aggressive and effective use of WSSC's legacy Maintenance Management Information System (MMIS) data and geographical information system. To support this task, Camp Dresser & McKee (CDM) developed a custom ArcView application for the WSSC Systems Infrastructure (SI) Group. The custom application allows WSSC to capitalize on its extensive historic and spatial data to make more prompt, educated, and efficient decisions regarding capital outlays to meet customer needs for reliable, clean water.
