01 · Water
Rainwater catchment, hand-pump wells, slow-sand filters, and pulling drinkable water straight out of the air when the aquifer is gone.
Water Sourcing
Catchment, hand-pump wells, slow-sand filters, and atmospheric collectors that pull drinkable water out of low-humidity air — 32 builds sized for a household, not a research lab.
Filtration & Treatment
Slow-sand, ceramic, charcoal/biosand, and improvised distillation setups that turn suspect water into safe drinking water without a hardware store.
Long-Term Storage
Rotating cisterns, buried tanks, IBC totes, food-grade drums, and the rotation schedule that keeps a stockpile potable across seven years.
Distribution Plumbing
Off-grid pump manifolds, gravity-fed header tanks, freeze-protective line burial, and the field-repairable fittings that hold up without a plumber.
