When planning toilet facilities for public events, the number of expected occupants is a primary consideration because it directly impacts the adequacy and accessibility of the restroom facilities. Estimating the expected crowd size allows planners to determine how many toilets will be necessary to accommodate the attendees comfortably, ensuring that there are enough facilities to prevent long wait times and to maintain a sanitary environment. This consideration helps in providing convenience and meeting health standards, which are critical for public gatherings.

While other factors such as the design of the stalls, the location of water supply points, and average daily water flow are important, they are secondary to understanding how many people will be using the facilities. Without an adequate number of toilets based on the anticipated number of occupants, even the best-designed facilities or well-placed supply points won't effectively meet the needs of the event attendees.
