Source of Firewater

I expect now that you know the minimum required amount of firewater. We have to find where to get it. 

- Is there a nearby water source like sea, river, or pond?

- Is the utility water, supplied by the utility company is reliable?

- Can I get water from underground water wells?

The firewater could be taken from the nearby body of water; sea, river, or pond. If not, then we have to store the firewater that will be used only for fire fighting. The most common way of storing the firewater is by storage tanks. 

What should be the capacity of your fire water storage tank? It depends on the expected fire hazards and fire fighting. Actual fire can last for days or it can be extinguished within 30minutes. Therefore, it is best to be guided with local regulations or international standards when deciding for the capacity of the storage tanks. Some industrials plants have a minimum off 1.5hours storage capacity sufficient for continuous fire fighting the largest demand. In refineries and bulk terminals, the fire water storage tanks ranges from 4hours to 6 hours.
