Does San Antonio Have Hard Water
San Antonio is known for its hot and dry climate, which means that water is an essential resource for homeowners. However, many residents in the area are concerned about the quality of their water, specifically whether or not it is considered “hard.” Hard water is water that contains high levels of dissolved minerals, such as calcium and magnesium.
According to the San Antonio Water System (SAWS), the water in San Antonio has a hardness level of 357 milligrams per liter (mg/L), which is equivalent to 357 parts per million (ppm). To put this into context, the United States Geological Survey (USGS) defines hard water as having a concentration of minerals greater than 180 ppm, which means that San Antonio’s water is classified as “very hard.”
Another way to measure water hardness is by using grains per gallon (gpg). In the case of San Antonio’s water, the hardness level is 21 gpg, which is considerably higher than the recommended level of 7-10 gpg. This high level of hardness can lead to a range of problems in your home, from clogged pipes and appliances to itchy skin and dry hair.

Texas Water Hardness
Water hardness is a common concern for homeowners across Texas, as the state’s drinking water comes from a variety of sources, including rivers, lakes, and underground aquifers. In fact, according to the Texas Water Development Board (TWDB), the state’s water supplies are sourced from more than 9,500 public water systems, which serve nearly 28 million Texans.
The level of water hardness in Texas can vary depending on the region. For example, in areas with high levels of limestone, such as the Hill Country, water hardness can be particularly high. In fact, some areas in Texas have reported water hardness levels as high as 40 gpg, which is considered extremely hard.
However, not all areas in Texas have hard water. In some regions, such as the East Texas Piney Woods, the water is naturally soft, with a hardness level of less than 3 gpg. Additionally, some water systems in Texas use water softening treatments to reduce the level of dissolved minerals in the water.
What is Hard Water?
Hard water is water that contains high levels of dissolved minerals, particularly calcium and magnesium. These minerals are naturally occurring and can be found in the soil and rocks that water passes through as it makes its way to underground aquifers or surface water sources. While hard water is not harmful to human health, it can cause a range of problems in your home.
What are the problems caused by hard water?
One of the most common problems caused by hard water is the buildup of minerals in pipes and appliances. Over time, this buildup can restrict water flow, decrease the efficiency of appliances, and ultimately lead to costly repairs. In addition, hard water can cause damage to water heaters, washing machines, and dishwashers, shortening their lifespan and leading to premature replacements.
Hard water can also lead to other issues in your home, such as dry skin and hair. The minerals in hard water can strip your skin and hair of natural oils, leaving them feeling dry and itchy. Hard water can also cause stains on clothes, dishes, and fixtures, making them appear dull and dirty even after cleaning.
Who is San Antonio’s Water Provider?
San Antonio’s water is provided by the San Antonio Water System (SAWS), a publicly owned utility that serves over 1.8 million people in the San Antonio area. SAWS sources its water from a variety of sources, including the Edwards Aquifer, the Trinity Aquifer, and local rivers and lakes.
The Edwards Aquifer, one of the primary sources of water for the San Antonio region, is an underground limestone aquifer that stretches across central Texas. The aquifer is a critical resource for the area, providing drinking water for millions of Texans and supporting a range of environmental and economic activities.
SAWS is committed to providing safe, reliable, and high-quality drinking water to its customers. The utility employs a range of treatment methods to ensure that the water meets or exceeds all state and federal drinking water standards.

Where Does San Antonio Water Come From?
San Antonio’s water comes from a variety of sources, including underground aquifers, local rivers and lakes, and a desalination plant. The primary source of water for the city is the Edwards Aquifer, which is located underground and stretches across central Texas.
The Edwards Aquifer is a unique resource that provides a significant portion of the drinking water for the San Antonio region. The aquifer is a porous limestone formation that stores vast quantities of water underground. When it rains, the water seeps through the ground and enters the aquifer, where it is stored until it is pumped out for drinking water.
In addition to the Edwards Aquifer, San Antonio also sources water from the Trinity Aquifer, which is another underground formation located to the east of the city. The Trinity Aquifer provides an additional source of water for the San Antonio region.
Finally, San Antonio operates a desalination plant that treats brackish groundwater from the Wilcox Aquifer, located in nearby Atascosa County. The plant is capable of treating up to 12 million gallons of water per day, providing a valuable source of additional water for the city.
Is San Antonio’s Tap Water Treated?
Yes, San Antonio’s tap water is treated to ensure that it meets or exceeds all state and federal drinking water standards. The San Antonio Water System (SAWS) employs a variety of treatment methods to ensure that the water is safe and of high quality. Here are some of the treatment methods used:
- Coagulation and Flocculation – Chemicals are added to the water to help impurities clump together and form larger particles (flocculation), which can then be removed more easily.
- Sedimentation – The water is left to sit so that the larger particles that have formed during coagulation and flocculation can settle to the bottom of the treatment tank.
- Filtration – The water is passed through layers of sand, gravel, and other materials to remove remaining impurities.
- Disinfection – Chlorine is added to the water to kill bacteria and viruses that may be present.
- Fluoridation – Fluoride is added to the water to help prevent tooth decay.
In addition to these treatment methods, SAWS also monitors the water quality on a regular basis to ensure that it meets all safety and quality standards. Overall, San Antonio’s tap water is treated using a range of methods to ensure that it is safe and healthy for consumption.
Quality of San Antonio Tap Water
The quality of San Antonio’s tap water is generally considered to be high. According to the San Antonio Water System (SAWS), the water meets or exceeds all state and federal drinking water standards.
One of the key factors in the high quality of San Antonio’s tap water is the use of a diverse range of water sources. As discussed earlier, San Antonio sources water from the Edwards and Trinity aquifers, local rivers and lakes, and a desalination plant. This ensures that the water supply is not overly reliant on any one source, which can help to mitigate the effects of drought or other water shortages.
In addition, SAWS employs a variety of treatment methods to ensure that the water is safe and of high quality. These methods include coagulation and flocculation, sedimentation, filtration, disinfection, and fluoridation, as discussed in the previous section.
Overall, San Antonio’s tap water is considered to be safe and of high quality.
How Much Water Does San Antonio Use Each Year?
San Antonio is the second-largest city in Texas, with a population of over 1.5 million people. As a result, the city uses a significant amount of water each year. According to the San Antonio Water System (SAWS), the city uses an average of 139,000 acre-feet of water per year.
To put this in perspective, one acre-foot of water is equal to 325,851 gallons, which is enough water to cover an acre of land to a depth of one foot. Therefore, San Antonio uses roughly 45 billion gallons of water each year.
Texas Water Use and Consumption in Statistics
Texas is the second-most populous state in the United States and has a large agricultural industry, which makes water use and consumption a significant issue. According to the Texas Water Development Board (TWDB), Texas used a total of 16.2 million acre-feet of water in 2017, with 61% of that water used for agricultural purposes, 27% used for municipal purposes, and 12% used for industrial purposes.
In terms of water sources, the majority of Texas’s water comes from surface water, such as lakes and rivers, with groundwater sources making up the remaining portion. However, groundwater is an important source of water in certain parts of the state, particularly in rural areas.
What Can I Do About Hardness in My Water?
If you live in an area with hard water, there are a few options available to help reduce the negative effects of hard water on your home and appliances:
- Install a water softener: A water softener is a system that removes minerals from your water, such as calcium and magnesium, that cause hardness. Water softeners typically use a process called ion exchange to remove these minerals from the water.
- Use a descaler: A descaler is a system that alters the structure of the minerals in hard water, making them less likely to stick to surfaces and form scale. Descalers work differently than water softeners and typically use a magnetic or electronic process to change the structure of the minerals.
- Use vinegar: Vinegar is an acid that can help dissolve mineral buildup in your pipes and appliances caused by hard water. You can pour vinegar down your drains and run appliances with vinegar to help reduce the negative effects of hard water.
- Install a whole-house filter: While a whole-house filter won’t remove the minerals that cause hardness, it can help reduce other contaminants in your water that can cause issues. For example, a filter can remove chlorine and chloramines, which can dry out your skin and hair.
Conclusion
The quality and safety of your drinking water is an important consideration for homeowners. San Antonio’s water has a high level of hardness, but the city’s water treatment plants work to provide safe and clean drinking water to residents.
If you are concerned about the effects of hard water on your home and appliances, there are several options available, including water softeners, descalers, and whole-house filters.
