As part of a local trucking company’s ongoing stormwater treatment program, OurEvolution engineers were integral in permitting, civil design and construction support for the facility’s onsite stormwater detention and treatment system.  OurEvolution’s design consisted of site grading which conveys 100% of the onsite stormwater through vegetated bio-swales to a central detention and treatment pond which attenuates peak stormwater flows and provides 48 hours of detention time for settling and biological treatment.  The project was completed in the summer of 2013 and particulate discharge from the site has been in compliance with the plant’s discharge permit since construction.
