It depends on the type & spread of fire. Sometimes a fire can be put out only by 10 litres of water & while another time 10 lakh litre of water can not douse a fire.
Firemen have a specific formula they use to determine how much water they may need for a blaze. Some aspects of this formula include, the size of the building, the distance from other buildings, passageways in the building, the number of residents, and more. For large fires, it could take upwards gallons of water to control a blaze.

This quick-calculation formula is expressed as:
What happens to the amount of water used during a fire?
If control is not achieved within a reasonable period, the amount of water may have to be increased. If immediate knockdown of the fire takes place, the amount of water being applied can be reduced to minimize water damage to the structure and contents. If protective systems are contained within the structure, they should be noted in the pre-plan.
