City of Goldsboro Constructed Wetlands Project


FACT SHEET

  • Clean Water Managment Trust Fund (CWMTF) has provided a $1,640,000 grant towards building the constructed wetlands project. Anticipated total project cost is $3,215,000 with the City of Goldsboro providing the additional funding.
  • The project was one of the first awarded a grant by the CWMTF; the grant was submitted in June 1997, the CWMTF's first grant cycle after being established in 1996. CWMTF has invested over $35,545,570 to protect and improve waters of the Neuse River Basin. (Click here for list of CWMTF projects funded by river basin)
  • The project consists of building 40-acres of constructed wetlands (or man-made wetlands) inside clay-lined containment berms. Future plans include expansion by 20 more acres based on success of initial project.
  • The project will reduce nitrogen in the Neuse River by using the natural processes found in wetlands to further clean highly treated wastewater from the city's advanced treatment facility. This cleaning process is known as "polishing."
  • The polishing process depends heavily on plant species common to wetland environments. The Goldsboro constructed wetland project will include some 13 plant species. (Click here for species list )
  • Once the constructed wetlands are fully operational, one to four million gallons per day will be "polished" by the wetland plants.
  • Treated wastewater entering the constructed wetlands will have an average Total Nitrogen content of 3.2 milligrams per litre. The wetland plants are expected to "polish" the water to less than 1 milligrams per litre. The project is estimated to reduce Total Nitrogen by at least 10,800 pounds per year.
  • The wetland plants will also remove phosphorus, another nutrient, out of the water, providing a secondary benefit to the Neuse.
  • The City of Goldsboro plans to conduct a four-year study to demonstrate the effectiveness of the wetlands "polishing" treatment capability.
  • The constructed wetlands project is just one piece of Goldsboro's overall effort to reduce pollutants in the Neuse. The city is also building a reuse project on 114-acres of farmlands. The reuse water will be used to irrigate hay as well as the 145-acre municipal golf course. The NC Clean Water Management Trust Fund has contributed $789,360 to the reuse project. Total project cost is $2,958,000.
