Abstract:

The development of a geographic information system (GIS) based sewer network database for the Purdue University campus in West Lafayette, Indiana, is discussed in this paper. The database, which contains the physical attributes and condition ratings for all components of the sanitary and storm sewer system, will be used as a long range maintenance, management, and planning tool. It will also be used to evaluate current conditions of the sewer system. It will be utilized for scheduling maintenance and rehabilitation, prioritizing and tracking expenditures, and identifying trouble-spots within the system. The database will provide a mechanism by which the operation of the system may be changed from a crisis management philosophy, fixing breaks and blockages as they occur, to a more efficient and systematic prevention philosophy. The database creation consists of three phases. First, in the planning stage, the attributes to be included in the database are determined, and an appropriate labelling system is devised. Second, the required data are gathered through an extensive search of files and design drawings, as well as through field reconnaissance. Finally, the information is input into the Intergraph Modular GIS Environment (MGE) database. The outcome of this project is a powerful, interactive infrastructure management tool which will be of great benefit in the management of the sewer system.
