Gordon does all he can to conserve water in his garden following a long period of drought. He collects water from his water butt instead of using his tap and hose pipe. Then he shares out water from his watering can sparingly to each plant and applies mulch. Unfortunately, Percy Gnome insists on pumping water from the stream behind his gardens into his top of the range sprinkler system. Can Gordon teach Percy about water conservation before the stream runs dry?
