When any of the following conditions are met: the municipal water supply network or the main inlet pipe cannot meet the design flow rate for indoor and outdoor fire protection water supply; a single fire protection water supply line is used or there is only one main inlet pipe, with the design flow rate of outdoor fire hydrants exceeding 20L/s or the building height exceeding 50m; or the municipal fire protection water supply design flow rate is less than the building's indoor and outdoor fire protection water supply design flow rate, a fire reservoir should be set up.
Where any of the following regulations are met, a fire reservoir should be provided.

1. When the production and domestic water usage reaches a high volume, the municipal water supply network or the main water intake pipe cannot meet the design flow rate for indoor and outdoor fire protection water supply.
2. When a single fire water supply line is used or there is only one main water intake pipe, and the design flow rate of outdoor fire hydrants exceeds 20 L/s or the building height is greater than 50 meters.
