I am trying to develop some standard layers for our drawing templates and I need AUGI’s help. We do a lot of work with water treatment plants and sewage treatment plants. I’m trying to figure out the best way to differentiate all the difference pipes we use in our plants. For example, in our water treatment plants we have:

• Raw water in (above grade & below grade)
• Raw water out (above grade & below grade)
• Backwash In (above grade & below grade)
• Backwash Out (above grade & below grade)
• Filter By-Pass (above grade & below grade)
• Overflow Piping
• Gravity Drain (above grade & below grade)

How would you name you layers, trying to follow the national cadd standards?

Would you make the discipline designator Plumbing or Mechanical? How would you name the Major & Minor groups?

Any ideas or input would be appreciated.
