Spatially Enabling Data With GIS for Utility Waterways and Watershed Asset Management Program
Abstract:One of the difficulties in waterways and watershed asset management is the geographic distribution of assets. Such assets include reaches of creeks, both natural and constructed; storm drains, levees and pipelines that are linear in nature (though not necessarily straight lines in the case of creeks); and fixtures that are at specific locations within a creek (such as outfalls, weirs, grade control structures, flow diversion structures). The condition of the asset can change with respect to time; it can also differ within a reach or a stretch of pipeline.
An Asset Management program can be used to monitor the condition of each asset with respect to its level of service, manage the preventive and corrective maintenance, and manage the risks. A spatially enabled data system, based on a geographic information system, that contains the geographic and condition information helps implement such a program The condition data is used to determine the probability of failure (of the asset) to satisfy its level of service for the asset. The asset database contains information on the consequence of failure (of the asset) to the business operations, especially in a situation where different assets have different impacts. This is then used to develop and implement a strategy to manage the asset over time. For this, the asset hierarchy and information in the GIS system has to be synchronized with a work order management system, such as Maximo.
