In the context of water quality modeling, water age refers to the time it takes for water to travel from a water source to consumers. Water age is a general indicator of water quality, with lower water age indicating better water quality.
Knowing the water age in a pressurized network helps identify areas of the network where water may be stagnating, thus increasing the risk of bacterial contamination.
This information can be used to optimize network design and operation, minimize water losses, and improve the efficiency of water treatment processes.
