Hello. I am just forming up a 6' x 6' x 2' water garden/pond with 5" concrete walls which receives its water from a 4' x 4' x 2' pond directly above. This is to take advantage of a spring that has historically drained into the soil. The slab and walls are substantially reinforced with 1/2" rebar. Once the pond fills it will need a means to outlet/overflow. I was considering putting a 3" schedule 40 pipe through wall at the downstream end of the 6x6 pond at the base where the wall contacts the slab. Then attach 3" tee with a pipe going to the surface from the vertical hub for controlling overflow, and a removable clean out plug on the hub at the base to drain the pond.
Question: As a newbie relative to pond design and maintenance, does this design for controlling overflow and complete pond drainage for maintenance make sense?
Thank you
