Maybe
Normally the water pump groans or clatters when the bearings go. I have made the same conclusion as you, that it was a water pump, but I was wrong. It is most likely the belt slipping. I would put my money on the tensioner not the water pump. The guy who replaced the belt probably cranked the tensioner down a long way, and it never returned to its normal tension, so now the belt slips.

I'm just a DIY, not a mechanic.
