2007 - 2017


As part of the Bay Restoration Fund, which was signed into law in 2004 to improve Chesapeake Bay water quality, the Maryland Department of the Environment has identified 67 major wastewater treatment plants in the state that require upgrades to their Enhanced Nutrient Removal processes.  MDE has identified effluent from wastewater treatment plants as a major contributor to nutrients in the the Bay, and ENR upgrades are targeted at reducing a wastewater facility’s total nitrogen discharge.  Carroll Engineering has provided civil and structural designs for ENR upgrades at a variety of wastewater treatment plants in Maryland.  Projects typically include an assessment of existing facilities and processes, as well as designs to upgrade or replace equipment, including pump station, blending tanks, clarifiers, reactors, and filters.
