Can I see my usage for other services like water and sewer?

Yes, so long as OUC is your provider for those services. On your myOUC Online Profile, click on "History." In the "Service" drop down menu switch the view from electric to water or sewer and click "Load." The page will repopulate with the chosen information. If you select sewer, you will see the same readings and usage as the water meter unless you have additional water services such as Irrigation or Reclaimed Water.
