Rain barrel system built from 50 gallon Greek pickled pepper shipping barrels.
They have nice embossed Greek logos. They drain 1/2 the roof and I expect
about 100 gallons per 0.10 inch of rain. Excess water goes either to the
black barrel and yard. If the white drain pipe is rotated upward or plugged
the water backflows up to the diverter and then down the drain pipe to an
underground lateral system that supplies a couple of trees.
The red barrels are drained to the black barrel or yard using a siphon.
