Mr. Maxwell-Gaines received a B.S. degree in Civil Engineering specializing in water and wastewater from Texas A&M University in College Station. After college, he and his wife joined the U.S. Peace Corps and accepted volunteer positions in Suriname, South America. They were assigned to the remote village of Godo Olo which is located in the Amazon rainforest, deep in the interior of Suriname. They helped the village implement a water well project, provided after-school tutoring, and provided business training for the villagers. They spent 27 months serving in the Peace Corps. After returning to Austin in 2002, Mr. Maxwell-Gaines worked at a civil engineering firm that provided a breadth of project experience ranging from TMDL computer modeling projects for impaired streams in Texas, to subdivision design, to water and wastewater treatment plant design. He became a licensed engineer in 2007. In 2004, Mr. Maxwell-Gaines started Innovative Water Solutions LLC. IWS is a design/build water conservation company that focuses on the nexus of stormwater management and water conservation. The company designs and installs rainwater/stormwater collection systems, stormwater management systems including green infrastructure, and graywater reuse systems, as well as efficient irrigation systems and water conservative landscaping for residential and commercial projects.

To date, Innovative Water Solutions has installed more than 6,500,000 gallons of rainwater storage capacity across the state of Texas. Mr. Maxwell-Gaines has designed rainwater harvesting systems for numerous municipalities and institutions including: Texas A&M University; The University of Texas at Austin; City of Austin; Austin Independent School District (Texas); Wimberley Independent School District (Texas); Hays Consolidated Independent School District (Texas); Atmos Energy; Denton County, Texas; City of New Braunfels; San Jacinto River Authority; SeaWorld; Texas Department of Transportation; and Texas Parks and Wildlife.
