What components make up a municipal water system?

The components that make up a municipal water system include a water source, treatment plant, and distribution system.

The water source is fundamental, as it provides the raw water that is necessary for the entire system. This can come from various sources such as rivers, lakes, or underground aquifers. Once the water is sourced, the treatment plant processes it to ensure it meets safety and quality standards for consumption and use. This treatment might include filtration, disinfection, and other processes that make the water potable.

Finally, the distribution system is critical as it is the network of pipes, valves, and storage facilities that delivers the treated water to households and businesses within the municipality. This network ensures that clean water is accessible where it is needed.

In contrast, other options may mention components that are important for specific functions, such as firefighting or sanitation, but they do not encapsulate the complete structure of a municipal water system as comprehensively as the correct answer does. Thus, the trio of water source, treatment plant, and distribution system accurately reflects the essential components necessary for a functional municipal water supply.
