The Little Patuxent Water Reclamation Plant in Howard County, Maryland discharges treated wastewater to the sensitive Chesapeake Bay watershed.  To meet very stringent effluent requirements, a $110 million project to retrofit the existing plant to provide Enhanced Nutrient Removal was undertaken. The project utilized an alternative project delivery method, Construction Management at Risk (GC/CM) approach.  Stantec provided services to this project that included conceptual evaluation, a demonstration study, final process modelling, design, and engineering support throughout construction for retrofitting the plant. The presentation will review several components as well as unique challenges and opportunities of the project.
