**//__ Water Fountain Design Challenge __//** The MD Water Fountain should be chosen because of its simple, symmetrical and creative design as well as its eco-friendly properties. The materials used to create this ingenious and innovative fountain are 100% environmentally conscious, imported from Tile Metrics. This tile company, located in Florida, specializes in green alternatives that not only look incredible, but contribute to a sustainable and globally aware community. The materials used on the base of the fountain were imported directly from the corporation’s headquarters in hybrid cars being driven by volunteers. The base of the fountain is composed entirely of the company’s Eco-Terra tiles, made from 75-80% recycled marble or granite chips as well as a cement binder containing 5% fly ash, making these tiles moisture-resistant and excellent for high-traffic areas. The five water spouts themselves release water that circulates throughout the fountain, significantly decreasing the amount of H2O needed. Therefore, the MD Water Fountain is not simply a resilient work of art that a community can enjoy- it is also a constant reminder of the eco-friendly, globally conscious citizens that selected it.
