What is the term for a discharge point that directs waste water and storm water to surface waters?

The correct term for a discharge point that directs wastewater and stormwater to surface waters is known as an outfall. This is typically a location where the combined flow of stormwater runoff and treated or untreated wastewater is released into a natural water body, such as a river, lake, or ocean. Understanding the concept of an outfall is crucial because it plays a significant role in managing water quality and protecting aquatic ecosystems. Outfalls can be points of environmental concern as they can contribute to pollution if not properly managed, hence the importance of monitoring their impact on surrounding waters.

In this context, inflow refers to the movement of water into a specific area, often associated with incoming water rather than discharging it. A discharge system does not specifically identify the point where water is released into surface waters, as it is more of a general term describing the mechanisms involved in discharging water. Effluent is a term that specifically refers to the treated water that is discharged from a treatment facility, but it does not indicate the discharge point itself. Therefore, outfall is the most accurate answer in relation to the question asked.
