Yield:
- 1 acre * 1 inch rainfall per year = 6.273e+6 in^3 / year = 27160 gallons per year
- San Diego County 55 year average (minimum) rainfall data = 10.26 (3.41) inches
Usage estimate:
- 50-70% of household usage is outdoors (e.g. lawns and gardens), average American uses 100 gal/day source: CT DPH
- Average American uses 82 gal/day (29930 gal/year) source: USGS
- Average Californian uses 108 gal/day (39420 gal/year) source: National Environmental Education Foundation
- Average American drinks 44 ounces/day source: CDC
Sustainability Estimate 1: 10.26 inches/year * 27160 gallons/year/acre = 278661.6 gal / 39420 = 7 persons / acre
