While on the Cool House Tour in Austin last weekend, we came across one charming home in the middle of the city. The house itself was downright lovely, but what left us awestruck was the backyard. On their moderately-sized city lot, the family had an incredible veggie garden, six clucking hens in a covered run, a three-bin composting system, and a 2,000-gallon rain tank.
We have a standard rain barrel in our backyard, which holds about 70 gallons, so imagine seeing many times that size, in a backyard the same size as our own.
And you'd think that with the drought we're experiencing in Texas, that thing would be empty—but the owners said that one good rain (two inches) filled it about three quarters of the way. Can you imagine collecting 1,500 gallons of water from your roof from one night of good rain? With the right planning, it's absolutely possible.
We have yet to do the cost analysis, but since we have the space this is seriously something we'd consider. What about you? Obviously this isn't an option for smaller lots, but there are all sorts of creative ways to squeeze in a 1,000-gallon tank... Learn more at WaterCache.
