Outdoor Watering Schedule

The City implemented a new outdoor watering schedule in January 2021. The new watering days are based on the last number of your address and are now spread out over seven days rather than six to better balance water usage throughout the week.

The best time to water is before noon or after 7 p.m. The watering schedule is voluntary unless drought restrictions are in place; however, the City recommends you follow the schedule even when no drought restrictions are in effect.

New Outdoor Watering Schedule (effective 1/29/21)

Water Sources

Round Rock’s primary water source is Lake Georgetown. When needed, the City pumps water into Lake Georgetown from Lake Stillhouse Hollow. The City also supplements our lake water supplies with water from the Edwards Aquifer and Lake Travis.
