Relational database management systems and geographical information systems (GIS) are useful tools for managing voluminous amounts of data for more effective utility management. Developing a computerized maintenance management system (CMMS) can be accomplished with off-the-shelf software and an understanding of relational database systems. The District of Columbia Water and Sewer Authority's (DCWASA) Potomac Interceptor (PI) Branch did just that with the creation of the Potomac Interceptor Relational Database and GIS Management System. Implementation of the database allows for tracking the periodic maintenance of the interceptor, as well as assisting with regional planning and capital improvements to the sewer. The project has resulted in targeting areas of concern for possible rehabilitation or replacement of pipe segments, verification of structure and invert elevations as compared to the floodplain and regional groundwater elevations, assessment and tracking of odors and odor complaints from specific areas along the sewer, and a repair schedule for the damaged or defective structures identified in the condition assessments.
