Our water supply in Gwinnett County comes from Lake Lanier, which is in the Chattahoochee River basin. The headwaters of the Chattahoochee River above Atlanta comprise the smallest watershed that provides a water source for a metro area in the country. The maximum amount of water that Gwinnett County can draw from Lake Lanier per day is 150 million gallons. On the average, our county draws 110 million gallons per day during summer months.

Did you know: On average, each American uses enough water to fill 27 swimming pools per year!

How can you help reduce water waste outdoors?

*Please note: The current Gwinnett County watering restrictions allow landscape and lawn irrigation every day of the week beginning at 4:00 p.m. and ending at 10:00 a.m.

Outdoor water usage other than irrigation of plants is to follow the odd/even watering schedule:
Odd numbered addresses may water on Tuesdays, Thursdays and Sundays only (ex: 501 Jones Lane)
Even numbered addresses may water on Mondays, Wednesdays and Saturdays only (ex: 3998 Smith Road)


  • Don’t over-water or over-fertilize your lawn
  • Water lawns during early morning hours to reduce evaporation
  • Don’t let sprinklers water your street, driveway or sidewalk
  • Install water-efficient sprinklers and use soaker hoses
  • Regularly check sprinkler systems to be sure they are operating properly
  • Shut off automatic sprinkler systems when storms are approaching
  • Do not leave sprinklers or hoses unattended
  • Raise the mower blade to at least three inches; longer lawns hold moisture better


  • Mulch to retain moisture in the soil and control weeds
  • Plant native and/or drought-tolerant grasses, ground covers, shrubs and trees
  • Minimize the grass areas in your yard because less grass means less water
  • Do not hose down your driveway or sidewalk; use a broom
  • Check all hoses, connectors and spigots regularly. Replace or add washers if leaking
  • Avoid ornamental water features unless the water is recycled
  • Avoid recreational water toys that require a constant stream of water
