Where is the effluent of a pond generally located?

The effluent of a pond is typically located just below the surface of the water. This placement is often strategic to ensure that the effluent drawn off from the pond does not disturb the sediment at the bottom or the aquatic life that may inhabit those lower depths. By accessing the effluent just beneath the surface, the quality of the discharged water can be better managed, as it allows for the collection of clearer water that has undergone some level of natural filtration and treatment through the pond's biological and physical processes.

Effluent taken from near the surface can also be more representative of the water quality for treating or further processing, which is crucial in wastewater management systems. This is in contrast to the other locations, which would not provide the desired water quality or could interfere with the pond's ecological balance.
