Graytec features the patent-pending closed-loop Blue Circle System that uses an extra pipe stack to intake greywater from bathtubs, showers, and bathroom sinks before purifying it to potable quality (by US and Swedish standards), and then returns it back into those same showers, bathtubs, and bathroom sinks for direct reuse.  Graytec's second solution is the traditional open-loop Blue Eco System, which also intakes greywater from showers, bathtubs, and bathroom sinks, and then cleanses it for indirect reuses, such as washing machines, landscaping, and toilet flushing.  

Graytec's vision is to set a higher standard for in-building water and energy conservation in the same vein as to how LEED Architecture raised the bar for eco efficient building design.  We invite you to help us turn buildings blue!
