Gwinnett County is reminding residents to refrain from outdoor watering during the heat of the day.

Under state and local law, outdoor watering is allowed seven days a week but is prohibited from 10 a.m. to 4 p.m. because it’s likely to evaporate before it soaks in.

For all other outdoor water uses, like filling swimming pools or washing cars, residents must follow an “odd/even” schedule. Even and un-numbered addresses can use water on Mondays, Wednesdays and Saturdays. Odd addresses may use water on Tuesdays, Thursdays and Sundays. No addresses may use water for those purposes on Fridays.
