Which step is typically performed after treatment to make water readily available for use?

• A. Potable water enters distribution system
• B. Potable water stored for use
• C. Potable water transported to different sites
• D. Water is heated before distribution

Answer: (B)

After treatment, storing potable water for use is the step that makes it readily available. Storage provides a buffer between the treatment process and the point of use, allowing the system to meet varying demand, maintain adequate pressure, and supply users during peak times or during any temporary disruption in treatment or pumping. Heating water isn’t standard practice for delivering drinking water and would waste energy, while transporting to different sites and feeding the distribution system occur after storage as part of moving the water to users. The essential idea is that keeping treated water in storage ensures it’s immediately available when needed.
