Is an open distribution system booster designed to pump to a higher-pressure zone that is closed to the atmosphere?

In the context of water distribution systems, an open distribution system typically refers to one that is open to atmospheric pressure, allowing air to be free to circulate within the system. A booster pump designed to elevate water pressure to a higher-pressure zone that is closed to the atmosphere would not function effectively if the system is open since it needs to create and maintain positive pressure within a closed system to ensure that water flows properly and does not allow for contamination or air pockets.

In a closed distribution system, a booster pump can effectively raise the pressure because it operates against a controlled environment, ensuring that the water delivery to higher pressure zones is efficient and safe from the vulnerabilities associated with an open system. Therefore, the correct answer reflects the characteristics of water distribution systems and the function of booster pumps.
