Water is a precious resource, and in San Marcos we’re fortunate to have some of the purest water thanks to the Edwards Aquifer. 

To protect our river and the endangered species that depend on it, conservation is critical. With dropping aquifer and Jackson Well levels, Texas State is now under Stage 3 drought restrictions. 

Explore this page to learn how you can reduce water use and support a more sustainable future.

Groundwater Availability

Groundwater availability in Texas is projected to decrease from 13.3 million acre-ft per year to 10.1 million acre-ft per year in the next 40 years.

Increased Demand

In the next 40 years, water consumption will double throughout Texas from 4.9 million to 8.4 million acre-ft consumed per year.

Texas will double by 2060 - 25 million more people

If consumption patterns do not change, the state may experience devastating economic and ecological impacts.

TXST Water Conservation Strategies

University Facilities: University Facilities teams are increasing conservation practices in various efforts such as; draining all fountains, deferring fire hydrant and pump flow testing, and further accelerating the repair and installation of water meters across campus.

Water-Wise Landscaping: The University is prioritizing the use of native and drought-tolerant plants, expanding no-mow and low-mow zones, and incorporating xeriscaping to reduce overall water demand while maintaining healthy and native landscapes.

Advanced Irrigation Management: The University is reducing irrigation schedules by 25%. The University’s irrigation systems are centrally monitored and utilize high-efficiency components, including drip irrigation. Watering is scheduled during nighttime hours to reduce evaporative loss and ensure responsible water use.

Water Conservation Tips

Six ways to help conserve water. Every drop helps.

1. In the Kitchen

  • When washing dishes by hand, fill one sink with wash water to avoid running the tap. 
  • Only run the dishwasher with a full load.
  • Don't use running water to thaw food. Defrost food in the refrigerator for water efficiency and food safety. 
  • For cold drinks keep a pitcher of water in the refrigerator instead of running the tap. 
  • Designate one glass for your drinking water each day or refill a water bottle. This will cut down on the number of glasses to wash.

2. In the Bathroom

  • Shorten your shower time. A 10 minute shower uses approximately 25 gallons of water. 
  • Turn off the tap while brushing your teeth.
  • Upgrade your restrooms fixtures with low flow features. 
  • Consider every flush. Older toilets use up to 7 gallons of water per flush. 
  • Turn off the tap when shaving. Fill a sink with water before a shave. 
  • While you wait for your shower to warm up, stick a bucket under the faucet to collect water, to water your indoor plants. 

3. In the Laundry

  • The average residential washing machine uses approximately 41 gallons of water per load. 
  • Only wash clothes when there is a full load to do. 
  • Wash clothes in cold water to save water and energy. 
  • ENERGY STAR certified clothes washers use about 25% less energy and 40% less water than regular clothes washers.

4. In the Yard

  • Water only when needed. Feel the soil and use a soil moisture meter to determine when to water. 
  • Water lawns and plants early in the morning to avoid water loss during evaporation. Check local restrictions for watering practices. 
  • Consider changing your outdoor space to a xeriscape to reduce water consumption and encourage native plant use. 
  • When it does rain, stick a bucket outside and use the collected water to water your indoor plants. 
  • Set automatic sprinkler systems to provide thorough, but infrequent watering. 
  • Top your garden beds with mulch or compost to maximize water retention. 
  • Use a moisture meter to determine when house plants need water. More plants die from over-watering than from being on the dry side.

5. Plumbing and Appliances

  • Check water requirements of various models and brands when considering purchasing any new appliances. Some use less water than others.
  • Check all waterline connections and faucets for leaks. A slow drip can waste as much as 170 gallons of water EACH DAY, or 5,000 gallons per month, and will add to the water bill.
  • Learn to repair faucets so that drips can be corrected promptly. It is easy to do, costs very little, and can mean a substantial savings in plumbing and water bills.
  • Be sure the water heater thermostat is not set too high. Extremely hot settings waste water and energy because the water often has to be cooled with cold water before it can be used.
  • Winterize outdoor spigots and faucets when cold temperatures arrive to prevent pipes from freezing and bursting.

6. Take a Dip

If you can, take a dip in a natural swimming hole to help cool your body temperature down. The San Marcos River is 72 degrees year-round!  

Edwards Aquifer Data

The Edwards Aquifer Authority is a groundwater district, mandated by the 1993 Edwards Aquifer Authority Act. The EAA regulates the portion of the Balcones Fault Zone Edwards Aquifer – a jurisdictional area that provides water to over 2.5 million people, and covers more than 8,000 square miles across eight counties.
