Integrating Sanitary Sewer System Automation with GIS
System Design
The primary function of an automated sewer management system is to provide users with tools
for sewer data collection (such as inventory, inspection, etc.), data management (such as billing
account management), maintenance planning, and management (such as job scheduling, work
order generation, cost estimate, etc.). At the system design phase, a conceptual model of the
system design which fi.mctions as building blocks for the system was defined; then the system
functionality was determined based upon the municipal sewer management activity needs.
Conceptual Design
Figure 2 illustrates the conceptual model of system design. The Sewer Management/
Maintenance Activities Block provides the driving force for the system design. It incorporates
business functions, such as inventory, inspection, rehabilitation, etc., into computerized
functions. A management function menu system will be developed for this block. The Graphic
User Interface (GUI) Block provides interfaces between management activities and databases.
An example could be a command button or a menu item to initiate functions for TV inspection.
The GIS Function Block provides embedded GIS functionality through Graphic User Interface.
The Database Block supplies data for the system operations.

System Functionality
The system is developed for users at municipal sewer authorities or any sewer management
organizations. Because of the diversity of users’ experience with computers and GIS, in
particular, using Windows environment, all system functions were designed to be user-friendly.
Based on the municipal sewer system business process, the system includes the following
functionality:
