Go into Buy mode and you should see a ? box above the normal pane. Click on that and then choose the miscellaneous tab - in there, you can find the garbage can to replace the one you deleted.
Another way would be to save the house and household to the library. Then bulldoze it. Then replace it from the library. That should automatically generate the missing garbage can as well.
