While I lived in the midwest, there were large water storage towers that, while not particularly attractive added a level of visual interest while traversing the city. These rain collecting skyscrapers act similarly. Their existence gives residents another way to understand their city; the buildings are known for their specific purpose. It doesn't necessarily matter what the purpose is, just that it is manifest to the residents. Now I don't mean to downplay the importance of water conservation, I think that rainwater collection is a worthy design objective, but that is not the broader success of the design, the success comes in making people aware of their surroundings. So often traversing the landscape triggers our human autopilot, which in turn detaches us from our surroundings. This is one of many ways that we might begin to care more deeply about our communities and cities, through engaging architecture.
