It's pretty simple - each floor has glow stone with dirt on top of it, one block narrower than the width, on the alternating side as the previous floor. Each floor is 8 blocks wide by any number of blocks deep. Water flows down, breaks a floor and flows to the next floor and repeats until you get to the trough.
nice job
