Which is typically NOT a water processing step?

Showering is typically not categorized as a water processing step. Water processing steps refer to methods used to treat or condition water to make it suitable for use, such as drinking or industrial applications. Filtration involves removing solids and particulate matter from water, which enhances its quality. Chlorination is a disinfection process that uses chlorine to kill harmful bacteria and viruses, making the water safe for consumption. Softening is a process that reduces the hardness of water, typically to prevent scale buildup in plumbing and improve the function of soaps and detergents.

In contrast, showering is an end-use activity where processed water is utilized, rather than a method for treating or processing water itself. Thus, it does not fit the definition of a water processing step like the other options do.
