Rainfall Data For Santa Cruz County

Santa Cruz County Average Rainfall by Month

The average rainfall in Santa Cruz City is about 31 inches per year. With just a 1000 sqft catchment area and an assumption of a 20% loss rate, an average of 15,000 gallons per year is available for supplementing city water. In testing our Rain 2 Toilet Prototype, we found that a rain storage tank emptied and filled about 9 times per year! That means a 1000 gallon tank can save up to 9000 gallons of water. This efficentcy is found on the Rain 2 Toilet Systems and not the Rain 2 Garden Systems simply becuase the toilet is used year round, and most gardens/landscapes only use water in the dry/summer months.
