Special application piping for non-potable water service and distribution are available in PVC and CPVC.  Non-potable water pipe is always purple in color to ensure that water lines fit for human consumption are not crossed with non-potable water lines.  Codes require non-potable water pipe inside the structure to be purple water distribution pipe (i.e. CPVC).  If the non-potable water pipe is outside the structure, then you can use purple water service pipe (i.e. PVC).
