Enough with the leaks!

     No, WikiLeaks is not embarrassing me by dragging up any skeletons of mine.  It's my waterfall (actually, one of three in my water garden) that leaked over two gallons of water a minute since I built it in 2001.  After spending a lot of time looking for leaks, I tore apart the beginning of the system and rebuilt it--but in a new, simpler design.  This post is the first of two showing the work involved, this part having to do with its removal.  The second post will show the rebuilding.
     The waterfall drops its water into a small pool, which then splits into two streams.  After about 20 feet the water drops into two small pools.  Then it drains another 20 feet into the main pond in the water garden.  The first photo shows the start of the system, the part that was removed.  The second photo shows the left secondary pool and the right secondary pool (on the far right of the photo).  The only part of the waterfall I left intact was the concrete structure that held the top water tank.  After taking it apart, it was clear how lots of water could have leaked.  The new system leaks none.
