Understanding San Antonio’s Water Restrictions in 2025

Water, one of life’s most essential resources, is increasingly becoming a shared responsibility. For residents of San Antonio, Texas, 2025 brings a renewed focus on water conservation as the city navigates the challenges of drought and limited water supply. Adapting to water restrictions not only ensures a sustainable future but also helps preserve a resource vital to the community’s well-being.

This guide will break down San Antonio’s water restrictions for 2025, help you understand their importance, and share practical ways to comply with them efficiently.

The Importance of Water Conservation

Why should we care about water conservation, especially in a place like San Antonio? The truth is, Texas frequently faces water-related challenges due to its variable climate. Rapid population growth in cities like San Antonio only adds to the strain on water resources. By conserving water, residents can:

• Protect local ecosystems and wildlife.
• Ensure adequate water supply during periods of drought.
• Avoid higher costs associated with managing and distributing water.

The San Antonio Water System (SAWS) enforces water restrictions not as a hindrance but as a guideline to secure the future of water for everyone. With the cooperation of residents, these restrictions can make a significant impact.

Water Restriction Stages in 2025

SAWS uses a staged approach to control water usage during drought conditions. Each stage is activated based on the city’s water availability and environmental factors. Understanding these stages will help you plan accordingly and stay compliant.

Stage 1 Water Restrictions

When It’s Activated

Stage 1 begins when the 10-day average aquifer level drops below 660 feet at the J-17 monitoring well.

What It Means for Residents

• Watering with an irrigation system, sprinkler, or soaker hose is permitted only once per week. 
• Watering hours are restricted to midnight to 10 a.m. and 9 p.m. to midnight on designated days. 
• Water waste, such as runoff from sidewalks or overwatering, is prohibited at all times. 

Stage 1 is designed to encourage early water savings before conditions become severe. It’s a reminder to be mindful of everyday consumption.

Stage 2 Water Restrictions

When It’s Activated

Stage 2 kicks in when the 10-day average aquifer level dips below 650 feet.

What Changes

• Watering remains limited to once per week, but designated hours narrow to 5 a.m. to 10 a.m. and 9 p.m. to midnight. 
• Hand watering and drip irrigation are still options for plant care outside of restricted hours. 

Stage 2 reflects the city’s need to prioritize essential usage while reducing excess water waste. Residents are encouraged to reevaluate non-essential water activities during this stage.

Stage 3 Water Restrictions

When It’s Activated

Stage 3 begins when the aquifer level falls below 640 feet.

The Strictest Measures

• Watering is limited to once per week on your assigned weekday. 
• Watering times remain 5 a.m. to 10 a.m. and 9 p.m. to midnight. 
• Non-essential water usage, such as washing vehicles or filling pools, is severely curtailed. 

Stage 3 represents a critical call to action. It’s a reminder that collective efforts are necessary to maintain the region’s water supply through extreme drought.

Tips for Complying with Restrictions

Adapting to these regulations may take some adjustment, but there are practical steps you can follow to make it easier and more effective.

Optimize Irrigation Practices 

• Install Smart Irrigation Systems
  • These systems only water when necessary, adjusting for weather patterns and soil moisture. 
• Focus on Early Morning or Late-Night Watering
  • Timing your watering cycles ensures minimal evaporation and maximum benefit for plants. 

Make Your Landscape Water-Wise 

• Use Native Plants
  • Texas natives are drought-resistant, requiring less water and maintenance. 
• Add Mulch Around Plants
  • Mulch reduces evaporation and locks in the soil’s natural moisture. 

Adopt Water-Efficient Habits at Home 

• Fix Leaks Promptly
  • Leaky faucets and pipes can waste gallons of water daily. 
• Upgrade to Water-Efficient Appliances
  • Consider switching to low-flow showerheads, faucets, and toilets. 

Collect and Reuse Water 

• Harvest Rainwater
  • Install rain barrels to collect and store water for outdoor use. 
• Reuse Household Graywater
  • Water from washing machines (excluding those used for diapers) can often be reused for irrigation.

Staying Updated and Taking Action 

Water restrictions may change as aquifer levels fluctuate throughout the year. Staying informed is key to remaining compliant and contributing to the city’s water conservation goals. For the latest updates, visit the San Antonio Water System (SAWS) website. You’ll find detailed guidelines, tools for planning your weekly watering schedule, and additional resources to help you make smarter water choices.
