Michael,
We switched some of our largest fairway bunkers to waste bunkers two years ago. The first year we told the members if it did not have a rake it was a waste bunkers. We allowed some grass to grow in the sand. When the grass became too thick we thinned it out with Round-Up. We machine rake them once or twice a week.
Caddies would sometimes throw the rakes from our normal bunkers into tall grass so golfers might not see the rake and think a regular bunker was a waste bunker. A member came up with an idea that has worked well. We hand planted some clumps of Lovegrass in all bunkers that are waste bunkers. We still allow some other grass to grow in them but the clumps of Lovegrass shows the golfer right away that it is a waste bunker. I have attempted to attach a picture. If I did it correctly perhaps it will help give you some ideas.
