And, here you can see irrigation lines that had to be routed around the filter pit. One of the lines carries water at all times (busted during excavation, of course; but fixed ... amazing more irrigation lines have not been destroyed, but not done yet!). It is the one with stub heading toward the filter pit wall. One of our ad lib changes is to add a water line to the pit. Since the line runs so close, it was an easy decision to make. Maybe in the future there could be an auto-fill device added, as well as a spigot? ... LOL. It is going to get cramped in there!
