Public Utilities
G&D has provided engineering consulting services to municipalities throughout North and South Carolina. Some of our services have included:
- Veteran's Park Sanitary Sewer, Shelby NC
-
G&D designed a new sanitary sewer trunk to replace several existing trunks and mains that experienced overflows during wet weather. The new sewer was part of a larger neighborhood improvement project, and it consisted of 2,000 linear feet of epoxy lined 20 inch diameter ductile iron pipe. Part of the new sewer main was encased in a 36-inch steel pipe that was installed via a bore under a state road.
- Thirteenth Street Water Main Replacement Project, Newton, NC
-
G&D assisted the City of Newton, North Carolina, in rehabilitating a portion of its water distribution system. As part of this work, G&D designed the replacement of the Thirteenth Street water main. Hydrant flow tests carried out under the supervision of G&D found that head losses through the existing pipe were very high and that the resultant pressures were very low. An EPA-NET model was developed to analyze the system. As a result of this analysis, G&D recommended the replacement of approximately 1,500 linear feet of four-inch diameter cast iron water main with new six-inch ductile iron pipe (DIP). This project also included the replacement of associated services and fire hydrants. Contract documents were prepared and the appropriate permits secured.
