That's awesome... Do you have power generator and stuff??? What have you done for damp? Honestly I think you've made a good choice building it as I think the time when people will need them is coming and you're prepared!!!
My home has a solar array with full off grid batteries and that also powers the bunker and also have a natural gas Generac generator that powers both the house and bunker though if the shit really hits the fan could loose natural gas
The 10 x 50 bunker is totally water tight and has a pretty nice drainage system under it and an air filtration runs all the time circulating air
Its about 6 feet underground and has 2 blast proof doors, one at the main entrance behind a block wall very well concealed and an escape out the back that has a ladder to a hatch thats about 6" underground so no one can see it
For water when we bought this old farm it had a well we used for water and still use to this day for watering the lawn and washing vehicles and stuff like that and the well is plumbed to the bunker that has a hand crank in case we lost power
Power is my biggest concern if we lost the solar array for whatever reason
I guess to a degree I am one of those doomsday preppers but both my wife and I are very happy to have it
Most of my family thought it was silly but guess where they were when we were watching some of the riots happening nearby? Her parents were at our house "just in case"
