Haunted trail fundraiser three October weekends: how many porta potties, and how do we keep teen actors from messing with them?

Two standard units are not enough for a few hundred guests over four hours. The industry guideline for events is about one unit per 50 to 75 people for a four-hour event, and a haunted trail with a waiting crowd increases demand. You should go with three or four standard units placed in a cluster by the ticket line. You will also need at least one ADA-compliant portable toilet in the cluster to meet the ADA 5 percent cluster rule, and a handwash station.

Weekly service is the norm, but for your event, you need a service visit after each Saturday night. Six nights of use by a few hundred people would overwhelm the holding tanks. The rental company will schedule a pump-out and cleaning before the next Friday night.

Teen actors can tip units or block vents. Staking and tie-downs prevent tipping. Place the cluster under a bright security light near the ticket area where adult volunteers are present all night. The visibility and supervision stop most pranks. A rental company can confirm their staking procedure when you book.

Brooke is right about the ADA unit and service frequency, but confirm the exact crowd size with your ticket sales from last year. A few hundred per night means you need at least four standard units plus one ADA unit and a handwash station to meet demand and the ADA cluster rule. The rental company will stake the units down with steel pins driven into the gravel, which prevents tipping. For teen actors, the best deterrent is assigning an adult volunteer to monitor the restroom area continuously during the event. Visibility stops pranks before they start. Also, request that the service driver checks the staking on each visit since gravel can shift.
