The general rule is this. You should have one porta potty for every 50 people for a one day event. If the event goes over night or lasts a couple of days then you should double the number of portapotties you have. Hence, if the event is going to go 24 hours or more then you should have 2 portable toilets for every 50 people.

Most city ordinances specifically spell out the requirement of a portable toilet on a construction site and inspectors will require that a porta potty is ordered and either placed on site or on its way before approving the inspection. In addition, OSHA requires a portable toilet on a construction site under the Safety and Health Regulations for a Construction (1923.51 (c) (1), 1926.51 (c) (3), (I), (ii), (iii), (iv) ). For information regarding specific city or country ordinances contact the city where construction is occurring or your local United Site Services office.

We will place your porta-johns at your event or on your job site per your instruction. We will make every reasonable attempt to accommodate your wishes as to placement on the portable unit. However, we will relocate the unit or notify you if it becomes necessary so that is readily accessible for servicing. This ensures that our trucks, employees and equipment are not in danger or at risk.

Royal Flush Portables offers portable wheelchair restrooms that are ADA compliant for use on a construction site, commercial area, or special event in some areas. Where available, our ADA units are large enough and obtain the proper elements to meet the standards that have been outlined by the Americans with Disabilities Act.

Portable toilets were designed for spaces without power or water so no lighting is available.  (Our standard units have shelves in 2 corners providing a place for the renter to place their own battery powered lights in the event lighting is needed).

When a tip over of a portable toilet does occur we ask that our customers contact our office as soon as possible to report the incident. We will then dispatch a driver to come to the site and clean the unit or switch out the portable toilet with a replacement depending on the severity of the tip over.
