This is the new mini-rainwater catchment system for the common kitchen.

Water runs off the roof into a gutter, where it is redirected into a pipe that feeds into the first water jug.

The water jugs are connected to each other via siphon pumps. Once primed, the siphon pumps balance the water level across all the water jugs.

Another siphon pump connects from the first jug to a piece of pvc which is connected to a spigot.
