Everything You Need To Know About Gwinnett County Water


Water is a cornerstone of life, and in Gwinnett County, the process by which it travels from source to sink is both intricate and exacting. Here’s an in-depth look at this journey.

Where Does The Water Come From?

Gwinnett County relies on two pivotal sources for its water:

  • Lake Lanier: A reservoir shaped by the Buford Dam’s influence on the Chattahoochee River.
  • Chattahoochee River: An integral river in the southeastern U.S., channeling essential hydration.

Collection and Preliminary Treatment

Upon extraction from these sources, water advances to designated treatment facilities. Here, it undergoes:

  • Screening: This process systematically removes substantial debris, ensuring only water progresses.
  • Settling: A phase where the denser sediments descend, segregating them from the upper clearer waters.

Comprehensive Treatment

Within Gwinnett County’s precincts, the water undergoes meticulous treatment:

  • Filtration: Using precise layers of sand, gravel, and occasionally charcoal, unwanted fine particles are trapped and removed.
  • Disinfection: Through the introduction of agents like chlorine or chloramines, microbial threats are neutralized.
  • pH Balancing: Adjustments are made to the water’s pH, aiming for a neutral state, ensuring stability as it travels through distribution networks.


Post-treatment, water finds temporary residence in storage tanks. Gwinnett County’s vast network of pipes then undertakes the task of distributing this treated resource to its destined locations.

Residential Destination

Navigating the residential pipelines, water first passes through the meter – an instrument that logs consumption for billing purposes. Once inside the property’s plumbing infrastructure, it’s dispersed to faucets, showers, and other outlets.

Quality Checks

To ensure consistency in water quality, Gwinnett County mandates routine tests, measuring the water against the stringent parameters set by authoritative bodies like the Environmental Protection Agency (EPA).

From the expansive body of Lake Lanier and the robust flow of the Chattahoochee River to the silent corridors of treatment facilities, Gwinnett County water embarks on a detailed journey. It’s a process defined by precision, care, and the goal of delivering essential hydration to its residents.
