Drinking Water Production
Gwinnett Water Resources provides high-quality drinking water to Gwinnett County residents. Water taken from Lake Lanier is processed by one of our two water production facilities, Shoal Creek Filter Plant or Lanier Filter Plant. After the filtration process, the water enters our distribution system of underground piping and storage tanks. Staff at all facilities continuously monitor and analyze water quality to ensure drinking water meets or exceeds all federal and state regulations for safety, based on the Safe Drinking Water Act and the Clean Water Act. Simply put, our water is safe to drink.
Water Quality at Home
The water produced in Gwinnett County is safe to drink directly from the tap and does not require boiling or filtering beforehand. Most issues with tap water originate in home plumbing systems. For example, black specks in the water are usually a sign of degrading internal plumbing. You can visit Resident Resources for information about what your responsibilities are as a homeowner.

Water Filtration Plants
Both of Gwinnett’s award-winning water filter plants, Lanier and Shoal Creek, pull water from Lake Lanier. Combined, these two plants can treat and distribute more than 25 billion gallons of clean water each year, providing drinking water and fire service for more than one million residents. Both filter plants protect public health and safety by using state-of-the-art treatment processes and monitoring water quality around the clock.
Gwinnett’s water quality goals are higher than those required by state and federal regulations, and our water is consistently compliant with the Safe Drinking Water Act.
