Full Description

With a population of over 650,000 people, Winnipeg is the eighth largest city in Canada.Faced with these growing challenges, the City's Water and Waste Department (WWD)retained UMA Engineering Ltd. to enhance current sewer maintenance and rehabilitationpractices, and provide a sustainable, defensible approach to system investment decisionmaking. In addition to establishing guidelines for condition assessment, rehabilitationand maintenance management, the Sewer Management Study called for the City toassess baseline condition for the entire sewer system using CCTV technology; thisinformation would be used as the starting point for an optimized global maintenance andrehabilitation program.The Study determined that recommended operational changes would create the need toeffectively manage the masses of data generated through a large-scale CCTV initiative.A way to streamline data analysis and use in evaluating system condition, rehabilitationand maintenance requirements was also needed.In the absence of a viable commercial solution, a custom "Sewer Management System"was developed around the City's technical, analytical and information requirements.Initially rolled out in 1998, the system, commonly referred to as the "SMS", has beenused to support the planning and management of over 3,000,000 ft of sewer inspection,$7.5 million (CAD) of maintenance and $50 million (CAD) of capital works; during thisperiod it has encountered and overcome numerous technical and functional challenges.This paper examines the infrastructure management concepts incorporated into theSewer Management System design, discusses the technical, functional, and operationalchallenges encountered through its development, implementation, and evolution over aseven-year period, and highlights future directions of the tool's continued growth. Includes 4 references, figures.
