SLIDE 42:  Collection

by Nate Downey

But branching is not always about distribution of energy (in the previous case, greywater). Branching can also be about collection and conveyance of energy (typically toward storage, filtration, and ultimately to distribution). It’s time, now, to look at the form of branching that collects and conveys. The blue arrows circles, and lines in this slide show the beginnings of that branching pattern. In the case of roofwater collection, we see short, stubby branches known as canales (much like the short, stubby see ends of the greywater pipes above. The canales dump runoff from the roof into catchment drains that are covered with river rock. These subsurface drain boxes are connected to 4” diameter undergound pipes that direct water toward a deisred goal that we’ll begin to see in the next slide.
