Ok, lets assume that the water treatment chemicals will only treat 900 gallons of water. I still think that's an awful lot of water for what's basically an oversized survival kit.
Just how much gear/water/food are people thinking is acceptable for something like the Survival Box? It's not meant to replace civilisation is it?

It is a refugee kit for 10 people in an nondetermined locale. 1 gallon per day per person for 90 days sounds about reasonable to me. Overall, I think it makes a nice base bug-out-box, and it worth replicating at a smaller scale as your own personal refugee kit. A 4-person version stuffed in an Action Packer tub would be a handy thing to have to throw in the vehicle in a bug out situation. Sure, it is not complete, but it is non-perishable and a good base.
