Round Rock · Watering

What days can you water your lawn in Round Rock?

Round Rock allows automated irrigation two days a week, set by the last digit of your street address: even-ending addresses water Wednesday and Saturday, odd-ending addresses water Thursday and Sunday, and only before 10 a.m. or after 7 p.m. Unlike Georgetown's drought-stage rotation, this is a permanent, year-round schedule.

Clay soil

Why a Round Rock lawn needs cycle-and-soak, not one long soak

Round Rock sits on the same slow-draining Central Texas clay as the rest of Williamson County. Clay takes water quickly only when it is dry and cracked, then infiltration slows to a crawl, so a single long run on your assigned day mostly runs off into the gutter.

Instead, use cycle and soak: split each watering into two or three short cycles with soak-in time between them, so the water reaches the root zone rather than the street. The US EPA WaterSense program recommends this same cycle-and-soak method specifically for clay soils and slopes. Source: US EPA WaterSense. The clay science is identical to Georgetown's, covered in depth in the Georgetown watering guide; only Round Rock's assigned days and hours differ.

How much

How much water does a Round Rock lawn actually need?

Match irrigation to evapotranspiration (ET), how much water the lawn loses to evaporation and plant use, not a fixed number. AgriLife recommends replacing about 60 percent of ET using local weather data. In practice that means deep, infrequent watering on your two assigned days in summer, with automated systems off in spring and fall when rain and cooler temperatures usually suffice.
