Which is NOT an example of a point of water use (POU)?

• A. Public water main tap
• B. Bathroom sink
• C. Kitchen faucet
• D. Shower head

Answer: (A)

A point of water use (POU) refers to any location within a plumbing system where water is utilized, such as sinks, faucets, and shower heads. These are the fixtures where users access water directly for various purposes, including hygiene, cooking, or cleaning. The choice identified as the correct option, the public water main tap, does not qualify as a point of water use because it is part of the broader water distribution system. It serves as a connection point from the municipal water supply rather than a fixture where individuals directly use the water. In contrast, the bathroom sink, kitchen faucet, and shower head are all specific fixtures designed for direct consumption or use by individuals, thus fitting the definition of POUs. Understanding the distinction between points in the distribution system and actual points of usage is essential in managing water quality and assessing risks such as Legionella exposure.
