Venice: All the boats

I am somewhat obsessed with the infrastructure of Venice, including transport. There are no cars, nor any other powered land-based vehicles. Everything is transported by land on foot or water by a boat of some type. Everyone gets around by foot or boat. I am unclear how the firefighters get the hoses to a fire. However, I was lucky enough to see the garbage boat in action taking a garbage basket that a garbage worker had brought to the canal.
