The waterways of Gwinnett County are affected by a variety of natural and human-induced factors. These factors include the natural processes of rainfall, vegetation, flooding, and erosion. However our everyday activities can have significant impacts that result from development, traffic, littering and illegal dumping, landscaping and lawn care, failing septic tanks, release of non-native aquatic organisms, and others.
The Gwinnett County Department of Public Utilities (DPU), in partnership with the County’s Planning and Development Department, and the County’s Department of Transportation, has initiated a study of the County’s watersheds to develop a better understanding of what affects the waterways and how water quality and habitat can be protected.
