Water Use Rules in San Antonio, TX: What Residents Actually Need to Know

If you live in San Antonio or are thinking about moving there, water use rules are one of those things you probably won't think about until they affect you directly. San Antonio has 2 specific rules on the books covering different aspects of water use rules, and some of them might surprise you.

Turf Replacement Rebates

SAWS WaterSaver Landscape Coupon, administered by the Conservation Department, pays residential customers for replacing high-water turf with drought-tolerant landscape, supporting drought-stage compliance and the Edwards Aquifer Management Plan.

Key details: Program: WaterSaver Landscape Coupon. Residential cap: Up to $400 typically. Minimum area: 200 sq ft turf removed. Plant list: SAWS native/adapted list. Inspections: Pre and post required.

Misrepresenting square footage or installing non-approved plants results in coupon denial and clawback. Letting replaced areas fail to remain irrigation-free for the maintenance period can trigger return of paid funds. SAWS may pursue civil collection.

If you are coming from a city with tighter rules, you will find San Antonio gives residents more flexibility on turf replacement rebates.

Lawn Watering Restrictions

San Antonio Water System enforces year-round watering schedules and tightening drought-stage restrictions tied to Edwards Aquifer levels at the J-17 index well, limiting irrigation to specific days and hours by address under the Aquifer Management Plan.

Key details: Default schedule: 1 day per week by address. Drought trigger: Edwards Aquifer J-17 well. Stage 1 threshold: 660 ft MSL for 10 days. Hand watering: Allowed any day. Authority: SAWS Conservation Ordinance.

Violations escalate from written warning to first citation around 250 dollars, second offense up to 1,000 dollars, and recurring violations up to 2,000 dollars. Persistent abuse can trigger flow restrictors at the meter at the customer's expense.

This is not one of those rules that cities tend to ignore. San Antonio actively enforces its lawn watering restrictions requirements.
