As part of field water treatment, after disinfection, what is the next typical step?

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

Answer: (B)

After disinfection, potable water is stored for use. This storage creates a buffer for variable demand and helps maintain a stable disinfectant residual, so that a safe, ready-to-distribute supply is available before the water enters the distribution system. Distributing immediately after disinfection can lead to fluctuating residuals and insufficient buffering. Taste testing isn’t a standard operational step, and moving water to different sites typically occurs after storage and planning, not right after disinfection.
