I'm just answering how I understand it, nothing political intended. Sanitary goes to WRF (Water Reclamation Facility) Video Here . I have talked to the city about BMP's and they have requirements and systems in place. Illicit Discharge Minimization BMP's for City of Bend Seen Here Page 8 is informative to some of your inquires. The City of Bend has told me that they are not actively enforcing these regulations at this time, they are in the education stage with future plans to have an enforcement team. As far as the waste hauler/disposer I don't know, like I said they municipalities I have dealt with look at me and my system the same as a carpet cleaner, not a sewage pumper. I really want to come to an event so I can discuss some of these issues we all face in a better environment for learning and discussion. It's hard doing this over the forum, accidentally deleted my response twice while typing! and half the time im surfing the forum on my phone or tab...
