WHY harvest rainwater?

WHAT is rainwater harvesting?
Rainwater harvesting is the collection of rainfall which falls on the roof of your home and stores it for future use. In a typical Central Cost residential landscape, a homeowner can store and reuse, on average, 25,000 gallons per year... enough to maintain a 400 square foot lawn and 100 landscape plants!

CALCULATE YOUR SAVINGS
620 gallons of water can be collected on a 1,000 sq. ft. roof with 1 inch of rain.
Therefore, .62 becomes our multiplier...
A 2,000 sq. ft. home in San Luis Obispo will retrieve an average of 19 inches of rain per year.
2,000 sq. ft. x (19 x .62) =
SAVE AND REUSE 23,560 gal. per year!
