Which statement best describes the role of turbine pumps in distribution systems?

• A. They are never used as booster pumps
• B. They are always the only type of pump used
• C. They are commonly used as booster pumps in distribution systems
• D. They cannot handle low pressures

Answer: (C)

Boosting pressure where it drops in the network is a common need in water distribution, and turbine pumps are well suited to that role. Vertical turbine pumps can develop substantial head and fit in compact pump stations or be placed in wells, making them reliable workhorses for pushing water to higher elevations or distant zones. Because of this capability, they are commonly used as booster pumps in distribution systems to maintain adequate pressure as demand varies. They aren’t the only type used, and they can operate across the pressure range needed for boosting, so the statement that they cannot handle low pressures isn’t accurate. In many systems you’ll find turbine boosters at key locations to keep pressures steady while other pump types handle different duties.
