The Water Gap: A Household Water Audit
A household calculator that estimates how many days your stored water will last and lays out the next steps for storage, treatment, resupply, and rationing.
Field notes
The homepage turns household water planning into a sequence of three linked measurements: hidden water already in the home, actual daily need, and days remaining. Its examples make the scale tangible, treating a 24-bottle case as about 3.2 gallons and a full bathtub as 60. The stated calculation also accounts for pets, adding 0.5 gallons per dog and 0.0625 per cat. The broader site describes 22 calculators covering storage, treatment, resupply, and rationing.
