Why is a water company a good example of a natural monopoly?

A water company is a good example of a natural monopoly because the infrastructure required to deliver water—such as pipes, treatment plants, and distribution systems—requires significant investment and is often not feasible for multiple companies to duplicate. This results in economies of scale, where a single provider can supply water more efficiently and at a lower cost than multiple competing firms. Additionally, having multiple water companies in the same area could lead to inefficiencies and increased costs for consumers, making a single supplier more practical for ensuring consistent and reliable service.
