Why are altitude valves used on water storage tanks?

Altitude valves are essential components in water storage systems, primarily because they serve the critical function of stopping the flow of water into a tank when it reaches its full capacity. This mechanism is crucial in maintaining the balance between inflow and the volume of water being stored, thereby preventing overfilling and potential spills or flooding that could result from excessive water levels.

The way altitude valves operate involves sensing the water level in the tank. Once it reaches a designated high point, the valve automatically closes, effectively halting any additional water from entering the tank. This action not only protects the physical structure of the tank but also ensures the efficiency of the water distribution system.

While there are other important components and considerations in water management, such as pressure regulation, overflow prevention, and water level measurement, the specific function of altitude valves is fundamentally about controlling the inflow of water to avoid overfilling. Understanding this role is key for water operators in maintaining safe and effective water storage practices.
