$60 million has been awarded by the Maryland Board of Public Works for upgrades to the wastewater treatment plant in Salisbury.
The money will go to design and building a system for Biological Nutrient Removal and Enhanced Nutrient Removal.
City officials hope this will cut the output of nitrogen by over 83 percent and of phosphorus by 85 percent.
The Salisbury wastewater treatment plant processes 8.5 million gallons a day.
