Thomas & Hutton provided engineering design services for the Dublin Wastewater Treatment Facility Expansion and Reuse Project, which consisted of the modernization of the existing facilities. Additional treatment processes included new influent pumping, improved grit removal, primary sedimentation, trickling filters, expanded secondary sedimentation, new chlorination facilities, and new sludge dewatering equipment to expand the facility from 4 mgd to 6 mgd. The tertiary treatment processes included a dual media filtration with a capacity of 2 mgd. The project included the reuse of water to Southeast Paper Co., which involved pumping 7,000 feet of 14-inch transmission line, a water quality monitoring station, and a 2,500-foot directional drill under the Oconee River. This project reduced the impacts to the Oconee River and assisted downstream users in their source water protection. The project was an innovative use of treated municipal wastewater to aid in conservation measures, as well as environmental impacts, and at the time of construction was one of the largest reuse projects in the southeast.
