The Perot Museum of Nature and Science in Dallas is one of 162 pilot projects designed according to the guidelines and performance benchmarks of the Sustainable Sites Initiative (SITES) rehabilitating a polluted urban brownfield. By collecting and recycling air conditioning condensation and rainwater, the irrigation water needs and almost 75% of the non-potable water needs of the museum are met. Kusser Fountainworks built and assisted in the design of two active as well as two passive, gravity-fed water features: The upper flume utilizing a filtered chlorinated process, and the bottom flume which is designed as a natural eco-friendly system supporting fish and plant life through a bio-filter operating without chemicals. Both flumes are made of architectural concrete which is stamped with animal and fauna prints.
During rainfall two gravity- fed mechanisms dramatically stage the flow of rain water collected on the roof tops:
∙ a stainless steel rain pipes feature located on the prominent upper plaza, which the collected rain water spills from. This water is then filtered through a bed of river rock and flows into a storage cistern.
∙ a waterfall in the northern corner of the site. At night miniature, 1W LED submersible lights which are flush with the concrete surface create celestial lighting patterns in the bottom flume.
