What ends up in a Waddell dumpster determines where it's allowed to go far more than how much of it there is. Two homes a few streets apart in Waddell can end up with different haulers, because Maricopa County's service boundaries don't always follow the town map. Your dumpster has two ceilings, not one: cubic yards and tons, and dense debris hits the second before it ever reaches the first.
1970s-2000s tract housing across the metros is typical for this area, which means plaster, lath and old flooring show up more often than drywall scraps. Stay on private ground and this does not apply. Move to the street and municipal right-of-way permits and heavy HOA involvement is now part of the timeline.
A single hauler rarely dedicates trucks to one town; the same fleet rotates through Waddell and the rest of Maricopa County by the day. Waddell doesn't support its own fleet of roll-off trucks, so your container is coming from farther out, and that means booking days ahead, not hours. Arizona demand rises and falls with desert heat with a summer monsoon season, not with the size of the job you are planning. A container on a private parking pad answers to no one but the property owner; one in a traffic lane answers to Waddell. Mark where any sprinkler heads or shallow irrigation lines run before the truck backs in; a container's weight can crack a line a few inches under turf.
