Porta Potty Rental for Concerts in Phoenix
An outdoor concert for 3,000 people over 5 hours with a bar comes out at about 20 units on the PSAI chart, or 24 to 26 after the alcohol bump. Maricopa County sets at least 30 for that crowd when permanent restrooms are not adequate.

Set breaks drive lines. Put urinal stations close to the bar and the main walkways to keep the stall lines moving.
If the venue has permanent restrooms, ask the permitting office how they count toward your total.
