Lake Lanier — formed by Buford Dam holding the Chattahoochee and Chestatee Rivers in northern Georgia — is key to providing water to the metropolitan Atlanta area. Approximately 60 percent of Georgia’s population receives drinking water from the Chattahoochee system, and the Lake Lanier watershed encompasses over 1,000 square miles and 10 counties.
The water intake facilities are located in a protected cove three miles from the Buford Dam, and provide a uniform raw water supply that is low in suspended materials, bacteria, dissolved organics, and metals. Gwinnett County operates and maintains two separate intake and pump facilities.
The Lanier Filter Plant can process 150 million gallons per day (mgd), and the Shoal Creek Filter Plant can process 75 mgd for a combined total of 225 mgd of water production capacity. The county also operates and maintains 10 water storage tanks and 14 booster pump stations.
The rehabilitation of the Lake Lanier Raw Water Pump Station included the rebuilding or replacement of pumps, the replacement of discharge ball valves and motors, electrical switchgear, and all electrical conduit cabling.
The contractor, Western Summit, had worked with GA Industries on other flow control projects in Georgia and chose the cost effective combination of GA metal seated ball valves, hydraulic actuation systems and GA surge arrestor valve, all of which could be supplied by GA Industries for single source system responsibility.
