The mathematical equation for rainwater harvesting is this:
For every inch of rain on 1000 square feet of roof equals 600 gallons of water!
That means the average house (2000 square feet of roof) in San Diego County, with our average of approximately 10 inches of rain per year, can catch 12,000 gallons of water off of their roof alone!!!
There is so much potential, even in drought years, you just need to have a place to store the water - like one of our ferrocement water tanks. Then, when your plants get thirsty you have the water on hand to give them a drink!
The key is to have a big enough tank, or multiple tanks, to store enough water that comes off of your roof. Take a look at the demand of your landscaping - do you have plants that need a lot of water, trees that need only a little in the summer, succulents, flowers, etc.?? Here at Permasystems we can help you understand your demand to help you better choose what size tank(s) best fits your home's needs. We offer initial in-home consultations for new customers. Plus there are $100's in rebates available so you can get your tank for cheap or even free! Learn more at the links below.
