What is the difference between a "distribution system" and a "transmission system"?

The distinction between a "distribution system" and a "transmission system" lies in their respective roles in the overall water supply infrastructure. The statement that a distribution system delivers water to consumers accurately reflects its primary function. This system includes the network of pipes, valves, pumps, and service connections that transport treated water directly to end-users, such as homes, businesses, and other facilities.

On the other hand, the transmission system's purpose is to move large volumes of water over significant distances from treatment plants to storage facilities, which might include reservoirs or water towers. This system is designed to handle high-pressure flows and is typically equipped with larger pipes to accommodate the bulk transport of water.

By differentiating the roles, the correct response highlights that the distribution system is the final stage in the water delivery process, while the transmission system serves as an intermediary stage that ensures treated water reaches storage points before ultimately reaching consumers.
