To access this raw water, Gwinnett County operates and maintains two separate intake and pump facilities. The raw water is then processed at one of the county's two water filter plants: 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 Water Production Division operates and maintains additional water production infrastructure, including 13 water storage tanks and 19 booster pump stations located throughout the County. State certified water production staff provides continuous monitoring and quality control of the water production infrastructure and equipment.
