IS THIS  FEASIBLE? Water runs off from rain and snow in Los Angeles through several concrete channels. During rainy season and the snow melt, this runoff is billions of gallons that just goes out to the sea. 

I can't for the life of me figure out what some, even a lot, of this water can't be diverted into underground reservoirs. With The Boring Companies Methods, these would be super cheap. We could store massive amounts of water for use in fighting fires this way. 

The aircraft have these huge hoses that they can use to suck the water up from these reservoirs, so their doesn't need to be surface exposure. 

2 questions. 
1. Do you see problems with this idea?
2. How do we get this idea to the folks who might do something with it?
