Goldsboro's water treatment program has gone to the dogs. In 2003, the Goldsboro Constructed Wetlands program began operation. The wetlands filter advanced treated wastewater through thirteen species of native plants before it flows into the Neuse River. A problem soon developed. Ducks and geese starting pulling up the plantings on the forty-acre project. To counter the waterfowl's activities, border collies, a breed noted for high intelligence, were trained to chase off the birds. The dogs work at least five days a week, and the plant destruction has been reduced.
