During emergencies, the Imperial Berkey can produce a maximum flow rate of up to 5.5 gallons (20.8 liters) per hour when configured with 2 Black Berkey elements, and up to 16.5 gallons (62.5 liters) per hour when fully expanded to 6 Black Berkey elements. As such, this unit can meet the water needs of 200+ people a day during an emergency.
NOTE: Maximum flow rate is calculated with upper chamber full to top. Flow rate decreases as water level declines. To achieve maximum output during an emergency, upper chamber must be maintained full at all times.
