How many handwash stations for a cluster of 10 porta potties?
Our festival is using a bank of 10 standard portable toilets, all in one cluster. The event runs for two days, about eight hours of public access each day, and we're serving food from local vendors and selling beer and wine. The units are on level grass in a city park, and a vacuum truck can get right up to them for service. I'm trying to finalize our order for handwash stations. Some of the planning guides I've seen suggest one station for every two or three toilets, but a friend who runs a construction company says they just put one station per cluster of units. I want to make sure we have enough for good hygiene without over-ordering. For a situation like this, is one station enough, or do we need to plan for more? Does selling alcohol change the calculation?
