Where does Dallas tap water come from?

Dallas currently obtains water from reservoirs including Lake Ray Hubbard, Lake Lewisville, Lake Grapevine, Lake Ray Roberts and Lake Tawakon. The water is treated by DWU (Dallas Water Utility) with chlorine and ammonia (which combines to make chloramine) and ozone to disinfect the water; lime and iron sulfate to remove suspended solids in the water and for corrosion control; activated carbon to control offensive tastes and odors; and fluoride to help prevent tooth decay. DWU tests the water 40,000 to 50,000 times every month, including tests for more chemicals than government standards require. Information about Dallas’ water quality can be found in the annual water quality reports. Dallas water is considered non-corrosive, which means that it is less likely to leach lead from pipes than water that is corrosive. Yet, we encourage Dallas residents (particularly those who live in older buildings pre 1986) to test their water for lead or to use a lead certified water filter. Despite that Dallas tap water adheres to strict regulation there are some risks of unregulated substances. Orb Media recently found that 94% of tap water in the US (and 93% of bottled water) contain microplastics. Although we don’t know the long-term impact on humans we do know that microplastics are do great harm to most sea life. Therefore it’s better to be safe than sorry and use a water filter that removes microplastics. Read more about microplastics in our interview with BBC.
