Yes, but please be aware this takes time. If every customer asks for an eta, it will be difficult for the dispatch department to do their job. The drivers are on a tight schedule in order to be as productive as possible, and they are prohibited from being on their phones for safety reasons. While dispatch does know where the drivers are through the day, it's not a simple thing to narrow down a specific time window for individual deliveries or pick ups (and this is with any hauler, not just our company). See the question "why can't you just ask dispatch for an ETA" for more information.
If you have a dumpster scheduled to be delivered or picked up, the driver could arrive any time between 8am and 7pm.
