How to Increment a String ID

I'm using ArcMap 10.2 and I have an ID that is part Arcronym part part number. I have created one script in the field calculator using Python to initially fill the field called FacilityID that I am populating as part of a Post Process. What I need is a script for after the first run that will get the last three digits that are a number and use this to autopopulate Null FacilityID's.

Here is my original script.

    rec=0
    def autoIncrement():
     global rec
     pStart = 1
     pInterval = 1
     if (rec == 0):
      rec = pStart
     else:
      rec += pInterval
     return "water" + "11" + "-" + format(rec, '04d')
