In addition to harvesting the solar on our site, we are seriously considering harvesting our rainwater. Eugene gets about 50 inches of rain each year. The rooftop of our main house is about 3,400 sq ft (remember, this includes porches and the garage), and our secondary unit has a roof area of about 1,570 sq ft.

There are several resources you can get online to calculate how many gallons of water this translates into. that’s helpful as we get into our irrigation demand and other things we might want to do with our water.
I’ve talked with the people from RainTech in Jacksonville, Oregon, just over 150 miles from here. Their system (pictured above), is called RainSpace. It’s underground, simple low-tech and just seems elegant to us. Visit their site, watch their installation video and see what we mean.
We’re hoping to use rainwater for all our irrigation and maybe even flush our toilets and wash our clothes with it. I’ll get into a bit more about that tomorrow. Meanwhile, check out RainTech, their green certifications and learn a little more about their company.
