How do you put a pipe through a dam?

When one just puts a straight pipe through a dam, the inlet can be completely covered with water, but due to the downward slope and faster flow of water, most of the pipe only runs at partial capacity. You will need to have an excavator to cut a trench through the dam to install this structure.

How does a pond overflow pipe work?

During normal rainfall events the pond will rise to the level the water will simply “run over” the overflow. This will happen with either a regular overflow pipe or a bottom draw style. With a bottom draw style the water column pressure will cause the overflow water to come from the bottom of the pond instead of the top.
