When does a handwash station need a fresh water hookup?
We're planning a three-day food festival in a city park, expecting around 2,000 people per day. I'm putting together the restroom plan and I'm looking at handwash stations. The rental company offers standalone stations with their own fresh water tank that need to be refilled, and also models that can hook up to a continuous water supply from a hydrant or building. The ground is level grass, and a vacuum truck can park right next to the placement area. For an event this size with food service, is a standalone tank sufficient if we schedule daily refills, or does the health department or the high usage make a continuous hookup mandatory? What's the tipping point for choosing one over the other?
