Ever wonder why our logo looks the way it does? Indigo's logo is a
representative of a water hyacinth. These useful plants are
used in natural wastewater treatment systems. The outer circle
represents the water cycle.
Our name is a nod to the industry convention of color coding potable
water as blue and reuse water as purple. We spend most of our
time somewhere in between.
