A standard portable toilet holds roughly 60-70 gallons of waste, and a single unit used by about 10 workers reaches capacity in around 5-7 working days. That 7-day interval is why weekly service is the default cycle for most Boston job sites and long-run rentals. A construction crew of 20 on a Dorchester or Roxbury build-out sharing two units will usually keep the weekly cadence; a crew that grows past 10 people per unit is the point where twice-weekly service prevents an over-full tank.
Each weekly visit is a fixed sequence. First the vacuum truck empties the holding tank. Next the interior gets a fresh charge of deodorizing blue fluid, roughly 3-4 gallons of water and treatment per unit. Then the seat, walls, and floor are washed and wiped, and paper plus sanitizer are restocked. The full stop takes about 5-10 minutes per unit once the truck is parked. On tight streets in South Boston, the North End edge near Faneuil Hall, or the dense triple-decker blocks of Jamaica Plain and Roslindale, the crew needs a clear path within about 100-150 feet of the unit because the vacuum hose reach is limited.
Access is the main variable in Boston. A unit staged in a driveway or open lot in West Roxbury or Hyde Park services fast. A unit inside a gated Back Bay courtyard, up a Charlestown alley, or on an East Boston parcel with restricted truck hours needs a confirmed access window and, where the unit sits on a public sidewalk or street, the correct City of Boston right-of-way permit. Units on private property need no city permit for servicing.
If a job runs a single unit for a small crew, weekly service keeps it usable without over-paying for extra stops. If a unit serves a festival, a large event on Boston Common, or a high-headcount site near TD Garden or Fenway Park, twice-weekly or event-day service is the fit because usage spikes empty a tank far faster than a 7-day cycle handles. Route days are grouped by neighborhood, so units in the same area are typically serviced on the same weekday to keep the schedule predictable.
