I'm a college student involved with providing tap water to large events. This is the first time we're going to try and provide tap water (instead of bottled water) at a huge event and we have no idea how to efficiently 'cater' the tap water. We're going to have a total crowd number of about 1000, and the diners will be rotating out of the dining room. So the room will generally hold 300-400 at a time. How many water coolers do we need so that we will have enough time to refill them and enough coolers to quench everyone's thirst? How many people should be on staff?
I'm not sure if I put this question in the right place. If not, please tell me where it should go. :)
