Which step involves moving treated water to multiple sites for distribution?

• A. Potable water enters distribution system
• B. Water is heated
• C. Potable water transported to different sites
• D. Water is chlorinated again

Answer: (C)

The key idea is how treated water gets delivered to many places. After treatment, the water enters the distribution system—the network of pipes, pumps, and storage that delivers potable water to homes, businesses, and other sites. The step that explicitly describes transporting water to different sites for distribution is this delivery through the distribution system, which is why it’s the best choice. Heating the water isn’t a standard part of potable-water distribution, and re-chlorination is about maintaining disinfectant levels rather than the act of distributing to multiple sites.
