What is the primary purpose of a hydropneumatic tank in a water distribution system?

• A. To store chemical treatments
• B. To control water temperature
• C. To maintain pressure
• D. To filter impurities

Answer: (C)

The primary purpose of a hydropneumatic tank in a water distribution system is to maintain pressure. These tanks are designed to store water under pressure and utilize the principles of hydrodynamics and pneumatic pressure to provide consistent water pressure to the distribution system. When water is drawn from the system, the tank releases the pressured water, which aids in maintaining an even flow and pressure throughout the distribution network. The tank typically employs a bladder or diaphragm that separates the water from the air, allowing for expansion and contraction as water is used and replenished. This ability to keep pressure stable is essential for ensuring that consumers receive adequate water supply even during peak usage times or when the system is in transition between pumping cycles. While chemical treatments, temperature control, and filtration are critical functions in water treatment and distribution systems, they are not the focus of a hydropneumatic tank. Thus, the tank's main role is fundamentally about pressure management, making it a vital component for operational reliability and efficiency in water distribution systems.
