By returning the water to the same watershed, Brad Lancaster creates a cycle of abundance that sustains not just one family, but the neighborhood and the entire ecosystem as well. He adds solar power into the mix, and plants food-bearing native shade trees to cool the home. The result is an oasis in the desert, with a model that can be applied in any community, from desert to coastal ranges and from remote rural homesteads to suburbia. Most important, it's a model that can help solve an impending water crisis facing communities across the globe.
