Does Austin Have Hard Water?


Austin has a water hardness level that is considered to be moderately hard. It is considerably less than what is considered hard. The City of Austin Water Utility states that the water hardness level in Austin is at the level of 84 milligrams per liter (mg/L) or 4.9 grains per gallon (gpg). This is considered moderately hard as per the standards for water hardness. 

Actually, any water that falls between 60 and 120 ppm is considered moderately hard. The moderately hard water does not cause any severe health issues. However, people in Austin will face the other issues related to the water – a few examples would include scum with soap, build-up of scale, and dry skin issues. 

Does Texas Have Hard Water?


Texas is known to have some of the hardest water levels in the United States. It has been observed that the average water hardness level in Texas is in the range of 200 ppm. It can be considered to be the 6th hardest level of water in the United States. It may be noticed that the hardness level of water changes from one region to another in the entire Texas state. 

Texas draws water from several sources, which include lakes and rivers and groundwater from aquifers. The actual water hardness level would largely be dependent on the location and source of water. Ideally, the water hardness level in Texas ranges from minimum to maximum. You would notice the water hardness level in Texas ranging from 50 milligrams per liter (mg/L) to over 500 mg/L. 

Where Does The Water Come From in Austin?


The water in the entire region of Austin is drawn from two significant sources viz the Colorado River and the Highland Lakes. Austin has a total of three water treatment plants that draw water from these two sources. 

The Colorado River is used as the main and primary source of drinking water in Austin. The highland lakes, on the other hand, are used as the secondary source for drawing water. In addition to drawing water, the Highland Lakes are also known for boating, fishing, and swimming.

The water treatment in Austin takes place through multiple steps and phases. That definitely makes Austin tap water completely safe to drink. 

The City of Austin Water Utility makes use of several treatment methods to help remove impurities and disinfect the tap water. The different methods and phases would include:

 

  • Coagulation: In this process, certain chemicals are added to the water to help you remove the impurities that clump together. 
  • Sedimentation: In this stage, the impurities are clumped together and made to sit at the bottom of the water supply. 
  • Filtration: The water is filtered through the layers of different items such as sand, gravel, and charcoal to remove any remaining impurities.
  • Disinfection: This stage kills and removes any bacteria and other microorganisms from the water. Chorine is the primary disinfectant used for cleaning water. 
  • Adjusting the pH: The pH of the water is adjusted to ensure that it does not corrode the distribution system and makes sure that the water does not get too acidic or basic. 
  • Fluoridation: This stage involves adding fluoride to the water.

How Is The Quality of Austin Tap Water? 

The tap water in Austin is considered to be of the best in the entire country. It is also considered to be the safest water to drink. Since Austin receives water from deeper wells and is sourced from the best quality reservoirs, such as lakes and rivers, it has been observed that the water in Austin meets all the guidelines as per the Safe Drinking Water Act (SDWA). 

The City of Austin Water Utility regularly tests the water so that it meets all the requirements that meet the quality standards as stipulated by the state and federal authorities. The 2021 Water Quality Report indicates that the tap water in Austin either meets or exceeds the guidelines and standards stipulated by the state and federal authorities. The tap water in Austin has been observed to be from contaminants such as lead, copper, and bacteria, and it is safe to drink.

How Much Water Does Austin Use Per Year?

Austin typically consumes around 140,000 acre-feet of water per year. In fact, Austin is allowed to use up to 325,000 acre-feet of water per year. Daily water consumption from Austin was 135 million gallons per day in 2020. 

The LCRA, or the Lower Colorado River Authority, has a partnership with the  City of Austin for the proper planning of water needs. As per the treaty, Austin is allowed to use up to 250,000 acre-feet of additional water through 2100. 

What Can You Do For Water Hardness in Austin?

Even when the hardness of water in Austin is established to be moderately hard, people in Austin do complain about a few issues, such as taste and other problems. 

You can use the following options to help you beat the hard water issues in Austin:

  • Water softeners: A water softener can help you remove the minerals from water, making it softer. It makes use of the ion exchange process to help remove the minerals. 
  • Reverse Osmosis: Reverse osmosis is a process used for removing the minerals from the water to up to 95 percent. However, if you have a high water usage, it may not be the right option to go with. 
  • Chemical treatment: Chemical treatment involves adding specific chemicals to the hard water. It involves the addition of chemicals such as chelating agents and sequestrants. This will prevent the chemicals from binding to the products from forming deposits.
