San Antonio Lawn Watering Rules & Schedule

Official irrigation schedule, municipal water waste penalties, and local agronomic guidelines for San Antonio homeowners.

Essential Compliance Takeaway

Irrigation in San Antonio is strictly regulated by San Antonio Water System (SAWS). Failure to follow assigned watering days or operating sprinklers during peak hours results in direct municipal fines.

Seasonal Irrigation Schedule

Enforced Policy

Summer Schedule (Critical Window)

Peak Heat

Stage 2 drought rules based on Edwards Aquifer levels. Automatic sprinklers limited to 1 day per week by address end digit (Mon 0-1, Tue 2-3, Wed 4-5, Thu 6-7, Fri 8-9). Hours: 7–10 a.m. and 7–10 p.m.

Spring & Fall Schedule

Stage 1 restrictions limit watering to 1 day per week during designated hours.

Winter Schedule

Year-round conservation guidelines encourage watering only as needed.

Water Waste Fines & Enforcement

SAWS citations carry municipal court fines starting at $150 and up to $500 per violation.

San Antonio Soil & Microclimate Strategy

San Antonio relies heavily on the Edwards Aquifer. High soil pH (7.8–8.2) and alkaline clay cause iron chlorosis in St. Augustine lawns; chelated iron applications are frequently needed alongside strict 1-day watering windows.
