What does the term "water age" refer to?

The term "water age" specifically refers to the length of time that water remains in the distribution system before being consumed. Understanding water age is crucial as it affects water quality; as water sits in the pipes, it may experience changes due to chemical reactions, temperature fluctuations, and biological growth. If water remains stagnant for too long, it can become a breeding ground for bacteria, lead to the deterioration of the water's taste or odor, and potentially impact public health. Monitoring water age helps water utilities manage distribution systems effectively, ensuring that consumers receive safe and high-quality water.
