Allowed Watering Hours
Round Rock's Standard Restrictions are a permanent year-round ordinance, not a temporary drought response. Outdoor irrigation is limited to 2 days per week with no watering between 10:00 AM and 7:00 PM. Even-numbered addresses water Wednesdays and Saturdays; odd-numbered water Thursdays and Sundays. Hand watering with a shut-off nozzle is allowed any day in the morning/evening windows. The schedule applies regardless of weather, Round Rock baseline conservation is built into the ordinance, with stricter Stage 1 through Stage 4 tiers available if Lake Georgetown or LCRA conditions deteriorate.

Citations begin Year-round permanent ordinanceπ HOA Rules During Restrictions
Texas Property Code Β§202.007 prohibits HOAs from fining homeowners for brown or dormant lawns caused by complying with mandatory water restrictions. The protection applies to Round Rock's permanent Standard Restrictions schedule, not just temporary drought stages.
If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the City of Round Rock Water Utilities's current restriction order. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your countyβs code enforcement division for assistance.
Why These Restrictions Exist
Round Rock, a Williamson County city of roughly 135,000 just north of Austin, operates a permanent year-round 2-days-per-week outdoor watering schedule under its Water Conservation and Drought Contingency Plan, distinct from temporary drought-driven restrictions. The city's primary water source is the Brushy Creek Regional Utility Authority (BCRUA), which draws from Lake Travis on the Lower Colorado River through LCRA Highland Lakes. Round Rock also draws from Lake Georgetown (North Fork San Gabriel River, US Army Corps of Engineers) with a conservation storage of approximately 42,500 acre-feet, shared with Georgetown and Leander. Round Rock is not on Edwards Aquifer water, the Edwards Aquifer crisis affecting San Antonio, San Marcos, and New Braunfels does not directly drive Round Rock's schedule, though regional Highland Lakes pressure does. The Standard Restrictions schedule applies regardless of drought stage; if conditions worsen, Round Rock can escalate to Stage 1 (1 day/week) through Stage 4 (full prohibition) under the same ordinance.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Round Rock area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.

Set sprinklers to run before 10 AM or after 7 PM, daytime irrigation is prohibited any day.
Bermuda and St. Augustine respond well to deep watering twice a week, 25 mm per assigned day is the right target.

Mow Bermuda at 1.5 to 2 inches and St. Augustine at 3.5 to 4 inches in summer, taller blades resist drought stress.
