How many standard units does a site need?
The count depends on how many people will use the unit and for how long, not on the square footage of the site. A technician asks about the crowd and the hours before suggesting a number.
A small site with a few workers can often run on one unit, while a crowd arriving in a single window needs more units than the same number of people spread over a week. When the answer is unclear, the technician usually plans for the busiest hour rather than the average, because a unit that fills early does no good for the next person in line. The number is confirmed before delivery, and a unit can be added during the rental if use runs higher than expected.
What does a site need before a unit arrives?
A level, firm spot, a truck route and a place to set the unit away from the entrance. Most problems on a site come from one of those four.
The ground is the first check. Gravel, compacted dirt, concrete and a plywood pad all work well, and soft ground that sinks under a loaded truck does not. The technician looks for overhead lines and confirms the unit will not block a gate, a driveway or a fire lane. The site contact should be reachable on the delivery day so the driver can ask where to set the unit.
How often is a standard unit serviced?
Service interval follows use. A unit that serves a crew all day fills faster than one that serves a ballfield on weekends, and the technician sets the schedule from that.
A holding tank fills in proportion to how many people use it, so the calendar alone is a poor guide. A unit for a weekday remodel is usually serviced on a set weekday, while a unit at a weekend event may be pumped between sessions or once at the end. Each service pumps the waste out, restocks supplies and checks the door and the vent.
What moves the price up or down?
Price is set by the job, not by a published rate card. Crowd size, length of the rental, access to the site, how often the unit needs service and whether it is an accessible or flushing unit all change the quote, and the price is explained and approved before work starts.
Length of time on site is the largest single factor. A unit placed for a weekend and a unit left for a year are different jobs with different service visits, and the quote reflects the number of visits and the days the unit stands. Access is the next factor. A spot a truck can reach from the street is simpler than one that needs a long hose line, a gate opened or a fence moved.
Can a homeowner or a crew service a unit themselves?
No. Pumping and emptying a holding tank needs the truck, the hauling permit and a disposal route, and the technician handles all three.
Portable-unit waste is treated as septage under Indiana rules. Anyone who removes it and transports, stores, treats or disposes of it needs a septage management permit from the state environmental agency before beginning, and the permit has to be carried in the truck. That permit belongs to the business doing the hauling, which is why a unit is serviced by the technician and not by a crew with a hose and a cart.
