You add the ground at plugs where the ground is needed most. Kitchen.bath wherever else in the house you think one is required. People like to have a grounding outlet at their computer stations.

In some cases it is moreso easy to simply add a plug using 12/2 with ground ,grounding the ground wire to a water line .
