| Once the main dig was complete, they started setting the bottom drains. A hole was dug out around where the drain was to be placed and 3 pieces of rebar driven into the ground to just the right height (checked by laser level) to rest the bottom drain lip onto. A trench was dug for each bottom drain line that extended past the outer edge of where the pond walls will be. The 4" pipe is glued to the drain and a cap placed on the other end of the pipe. Once the walls are complete, they will dig down outside the pond wall and tie into these lines. The air pits where also put in place. They are 6" higher than the bottom drains (refer to drawings in post #2). The photo may make them appear to be out of line, but they are each perfectly centered in the pond. Each was cemented in place, but only about half way up. This is to hold them in place during the pond bottom pour. Tomorrow they should be finish the detailed digging on the bottom; sloping the bottom from the sides down to the bottom drains.
