    2. 75 percent of California’s available water is in the northern third of the state (north of Sacramento), while 80 percent of the urban and agricultural water demands are in the southern two-thirds of the state
    3. parts of Northern California receive 100 inches or more of precipitation per year
    1. Why make freshwater when we could collect the water that falls from the sky? Even on the driest year in recorded history in 2013, it still rained 3.6 inches in Los Angeles. An inch of rainfall in L.A. generates 3.8 billion gallons of runoff, so you’re talking about more than 12 billion gallons of water that could be captured, but that flows within hours down our concrete streets and into the ocean. There’s enough rainwater to be harvested to produce 30-50% of the entire city’s water needs.

      The freshwater that falls on LA is lost.
