I am not sure about Vancouver as this is where the video is shown, but here in Calgary that video is a $10,000 fine. I called the person in charge of storm sewers and its laws a few weeks ago to ask a few questions. Here you can't even wash down extra dirt into the sewers unless it showed up naturally. If you wash your driveway and some oil comes up from an oil spot you get fined something awful as well. Since all the storm drains go right back into the main river and everybody down stream gets what we put in they are super strict here as well. I have had to turn away customers and turn down jobs as the cost of doing it right and getting caught if I do is not worth the job.
My problem with that video comes down to the hand wash they do at the end. I can't say time for sure, but I know I could not even come close to doing all that work and making very much $$$. Throw in the reclaim costs of equipment and drainage and I would have to charge way more then anybody would want to pay.
Other problem with all those tanks and the truck having a 12,000 lb gwvr you would be overweight if they were all full. I understand when one fills the other empties with reclaim, but if you run into the situation where you had to get water before you got rid of the dirty water you would be in trouble if you were caught.
