Which of the following components are NOT typically part of a water distribution system?

In the context of a water distribution system, air compressors are not typically included as a standard component. The primary purpose of a water distribution system is to transport treated water from treatment plants to consumers. It fundamentally relies on components designed specifically for handling and delivering water.

Pipes serve as the main conduits for the water, allowing for its transport across various distances. Fire hydrants are essential for providing access to water in case of fire emergencies, ensuring that fire services have the necessary resources readily available. Pumping stations are crucial for maintaining adequate pressure within the distribution system and helping to move water uphill or over long distances.

Air compressors, while pivotal in certain applications such as tools or pneumatic systems, do not play a direct role in the distribution of water itself. Their functions are more aligned with generating compressed air for operational processes that are separate from the water transport mechanisms. This distinction underscores why air compressors are not categorized as standard components of a water distribution system.
