Why do festival porta potties always run out of toilet paper by evening?

The portable toilet paper runs out because your event undersupplied the units and the Saturday morning service was not enough for a two-day festival. The industry guideline is one standard unit per 50 to 75 people for a four-hour event, and you need more units for alcohol, longer duration, and crowds with more women. For 3,000 people over two days, 40 standard units is too few. Each unit holds one or two rolls, and people use extra paper for seat covers or take rolls. A Saturday morning service visit is standard for weekly rentals, but high-use events need midday servicing or extra paper stocked inside. Event planners should order more units, specify extra paper restocks during peak hours, or use attendants to monitor supplies. The restroom trailer helps, but it also needs frequent paper checks. Clear truck access doesn't matter if the service schedule is wrong for the crowd size.

Deb is right on the supply, but she left out the paper itself. A standard portable toilet typically has a single-ply paper roll to reduce clogs, and that roll holds far less than a household roll. For a festival, the paper consumption rate is high. People use extra sheets to line the seat or wipe surfaces, and some rolls do walk away. The Saturday morning service visit restocked each unit, but that single restock was not enough for the entire day's peak use. Event planners should calculate paper supply by adding a mid-day restock for every unit, especially on the busiest day. Some operators can lock paper dispensers or place an extra sealed roll inside the unit during service to extend supply.
