What does 'Downstream' refer to?

The term 'downstream' refers to the direction in which water flows in a water course, such as a river or stream. When considering the context of water supply, 'downstream' indicates the path water travels after it has been sourced or treated, leading to the point of use or discharge. In this context, it describes the areas or systems that receive water from upstream sources, illustrating how water supply is distributed throughout a network.

Understanding this flow direction is essential in managing water resources effectively and recognizing the implications for water quality and supply. For instance, knowing what is considered downstream can help operators assess potential risks, such as contamination from upstream sources affecting water quality in the downstream areas. Therefore, the concept aligns with the broader scope of water management and public health, highlighting the importance of monitoring water quality as it moves through different segments of the distribution system.
