FEMA reported Saturday morning that they had moved 5 million liters of water, 5 million meals and 270,000 cots into Texas, where an estimated 572,000 people live within the storm surge area.
Wow! 5 million liters of water. This sounds like a lot. Is it? I ran some quick numbers.
This is a little more than 1.3 million gallons of water which is about the same amount of water that your community elevated water tank can hold. Now assuming everyone in the storm surge area needed water and they need 1/2 gallon per day, there is 2 gallons of water available per person which is enough for four days.
However, this assumes one can get water distributed efficiently to the people who need the water.
