** Annual Average Rainfall: 10.26 inches * 27,160 gallons/inch of rainfall = 278,661.6 gal / 39,420 gal/person/yr = 7 persons = about 2 average households
** Annual Average Rainfall: 10.26 inches * 27,160 gallons/inch of rainfall = 278,661.6 gal / 39,420 gal/person/yr = 7 persons = about 2 average households
** Minimum Rainfall: 3.41 inches * 27,160 gallons/inch of rainfall = 92,616 gal / 39,420 gal/person/yr = 2.4 persons
** Minimum Rainfall: 3.41 inches * 27,160 gallons/inch of rainfall = 92,616 gal / 39,420 gal/person/yr = 2.4 persons
Storage Capacity:
* number of people * daily water consumption (gal/person/day) * longest drought period (days) = needed storage capacity (gal) [https://www.harvestingrainwater.com/wp-content/uploads/Appendix3Calculations.pdf Source]
* 5 * 108 * 150 = 81,000 gal
