You can even attach a pulling cord if you affix it securely. up to the top of the vertical pipe. However, this can be pricey, especially in tall dams and dams with a long pipe run.

You can build a simple form made of 3- to 4- cm thick planks. Overflow water drops several feet down the standpipe, takes a 90 turn, and flows out the discharge pipe buried at the base of the pond embankment.

Design emergency spillway and calculate maximum water surface elevation based on a plugged outlet structure. A third type of pond is the excavated, or dug out, borrow pit pond. slab top, if you are using concrete.
