John Mitchell has 21 years of engineering consulting experience in Texas.  John started his engineering career in the Houston area.  Much of this work involved large municipal designs, but also included design and construction management on environmental remediation projects under the Superfund program throughout Texas and the country.  These remediation projects involved contaminated soil and water, including the design of groundwater treatment plants to remove toxic hexvalent chromium, a contaminant made famous by the Erin Brockovich film.  In the last 15 years, John’s career became more focused on municipal and civil work.  This work included large and small water and wastewater treatment plants, one such plant survived and continued to operate during hurricane Ike.  John has been heavily involved in municipal infrastructure work such as pump stations, lift stations, and wastewater lines, including one of the largest wastewater tunnels in Houston.   His career spans a range of project sizes, from the smallest subdivision lift station to storm water stations designed to remove high volume runoff from urban interstate.
