Sewage, storm water, or water that has been used for various purposes in the community are referred to as what?

The term that describes sewage, storm water, or water that has been used for various purposes in the community is wastewater. Wastewater encompasses a broad range of water types that are no longer suitable for use without treatment, including water that has been contaminated through various domestic, industrial, or agricultural activities. It is essential to manage wastewater effectively to mitigate its impact on the environment and public health.

Brackish water refers to water that has a salinity level between fresh and saltwater, typically found in estuaries, and does not directly pertain to the concept of used or contaminated water. Stagnant water is still water that does not flow, which can lead to water quality issues and does not specifically denote used or treated water. Surface runoff is the water that flows over the ground surface and does not indicate whether the water has been contaminated or utilized. Therefore, wastewater is the most accurate and comprehensive term for the described situation.
