Our primary us for rainwater will be for landscape irrigation. We’re designing our landscape first to need less water to start with. That’s the way it is with good design in anything, reduce is the first “r”.
So we’re being strategic in our plant selection, using the concept of the right plant in the right place. We’re reducing our actual lawn area to just about 100 sq ft. Lawns are the largest irrigated “crop” in the US, and we often use clean, drinking water to do it.
Then, after we reduce, we’re going to reuse (the second “r”) our rainwater that already would have fallen onto the ground where our house will be. The landscaping that needs irrigation will largely be fed by a drip system. Drip irrigation is hugely more efficient than pop-up heads.
We’re also looking at using rainwater for two of the major water-using “appliances” inside our home: our toilets and clothes washer. More on those next time.
