Flushing Porta Potty Rental in Philadelphia

Guests, hours and what's being served decide it. A three-hour afternoon party with lemonade puts less load on a unit than a five-hour reception with a bar. Flushing units also use their fresh water, so a long event with a big crowd may need more units, or a service visit partway through, so the flush doesn't run dry before the last dance.

Send the headcount, the start and end times and whether there's a bar, and the quote comes back with the count. For a job site, OSHA's table sets the minimum for the crew (29 CFR 1926.51(c)): one unit for 20 workers or fewer, then more as the crew grows. See How Many Porta Potties Do I Need? for the full table.

A flushing unit stands on its own base, so it needs a firm, level spot about the size of a parking space's end and a way for two people to carry or wheel it in. That's the reason it works where a trailer doesn't: a rowhome back yard reached through a gate, a courtyard behind a twin or a narrow side yard between houses.

Keep it a short walk from the party but away from the tables, in the shade if you can in July, with a clear, lit path for an evening event. On a block party or a sidewalk job, the unit stays clear of the curb ramp, the trash pickup and the neighbor's front steps.

Portable toilets at a public event need the Department of Public Health's permit, and a unit in a residential area has to be serviced at least every 48 hours under it. A private party at home doesn't need the city's permit.

Every service visit pumps the holding tank, refills the fresh water for the flush, washes the unit inside and restocks paper and sanitizer. A one-day party is set up clean the day before and picked up after. A job site unit is serviced at least weekly.

In freezing weather the flush water can freeze, so a flushing unit on a winter job site may be switched to a standard tank until spring. We'll tell you what makes sense for your dates.

For a party at home, the restrooms are part of the layout, not an afterthought dropped wherever there's room. A few decisions made early keep guests out of the house and the units out of the photos.

Most people's picture of a porta potty is a hot plastic box at a festival with an open tank under the seat. A flushing unit changes the two things that picture is built on: what you see and what you smell. The bowl is rinsed with fresh water on every flush, the tank below stays out of sight, and the deodorizer isn't fighting an open pit all afternoon.

That's why hosts who would never put a standard unit next to their back porch are comfortable with a flushing unit there, and why builders use them at an open house. It's the same footprint and the same easy placement, with a first impression that matches the rest of the event.
