What is With The Purple Sprinklers?

Some of you might be wondering why the new sprinkler heads are purple. As dictated by the state of Colorado, we are required to mark all irrigation components with the color purple for identification purposes of effluent water.

Not only are the heads marked, but all of the pipe is marked as well. The HDPE pipe has purple lines on it, while the low pressure pipe is all purple.

These markings are in place so that a cross connection with a potable water supply does not occur.
