At a higher level or as a next step after the initial ratings of the assets, utilities can gather data on asset condition through more sophisticated means and re-rate the assets. For example, a sewer pipe can be examined with cameras to determine the interior pipe condition. Water pipes can be evaluated using leak detection technology. A rating system as described above may still be used in combination with this higher-level data, or a more sophisticated numbering system can be used.
Asset condition will change over time as assets age and as they are used during normal operations. Therefore, the asset condition must be continuously updated to keep the data current. The time interval between updates may vary from utility to utility, but generally annually is a good time to revisit the condition assessment. In addition, as assets receive routine, preventative, or corrective maintenance, condition can be re-assessed and the resulting condition rating can be revised in the inventory.
Examples of the types of condition monitoring approaches that can be used to assess asset condition is presented in a table in Appendix A.

We have a numbering system. They're almost all 1 to 5. --Stacy Gallick, Johnson County, KS |
