Brightwater is the largest functioning membrane treatment facility in the world. Membrane technology, which can filter fine solids from wastewater, represents the state of the art for wastewater treatment. Membrane treatment produces exceptionally clean water suitable for water reuse applications, referred to in the industry as reclaimed water. Brightwater will produce 7 million gallons per day (mgd) of Class A reclaimed water for on-site and off-site use with an ability to expand up to 21 mgd as demand requires. Artist Buster Simpson wanted to offer this product up to visitors at the moment of first arrival. The Water Molecule, with its bright red oxygen and two white hydrogen atoms, feeds reclaimed water through a purple "straw" and a 100-foot long purple pipe to a natural filtration system. Within the plant an around the world purple pipe signifies reclaimed water where tetrapod forms hold up the pipe that the artist envisions as a metaphor for the heroic collective efforts of civic infrastructure. Required by code to provide notification that the water is non-potable, the artist translated "Hydrologic Cycle Repurposed" in 19 languages along the length of purple pipe. “Bio Boulevard and Water Molecule exemplify poetic, civic gestures in support of a sustainable water use mission. A series of large cast concrete figurative elements support an episodic sculptural tableau consisting of a large water molecule and a long conveyance pipe transporting reclaimed water. The system intends to facilitate bio mitigation through hydroponics, as well as being a water feature. The expressed water is offered to reconstructed wetlands and to recharge ground water." - Buster Simpson Buster Simpson, along with Jann Rosen-Queralt and Ellen Sollod, was a planning artist on Brightwater, contributing to the "Brightwater Art Plan" that served as a guide to all of the artwork in the treatment system.
