How it Works

Collecting Water As it Runs Down the Roof

To pilot this system, I used 18 water bottles ( 50.7 fl oz or 1.5 L each), creating a horizontal gutter-like system across an 11’8” roofline. Capitalizing on gravity, this half-pipe tubing is on a slight decline as it approaches the downspout, which is a piping system constructed solely of 17 fl oz (0.5 L) water bottles and heavy-duty, waterproof duct tape. This system allows any water that falls on all of the roof’s surface to be directed down through the tubing and successfully collected in a receptacle.
