Tesla’s Giga Texas increased its annual treated water use by more than 200 million gallons in just two years, raising concerns about whether Austin can fulfill its long-term water conservation plans as Elon Musk advances plans for a new semiconductor plant<\/a> expected to push demand even higher.<\/p>\n

From 2023 to 2025, Tesla\u2019s annual treated water use rose about 68% to 556 million gallons becoming Austin Water\u2019s third-largest customer \u2014 up from fifth in 2023, according to Austin Water. The increase is raising new concerns about how water limits are applied, as residents are urged to conserve water while large industrial users continue to expand. In March, Musk announced Terafab, a proposed $20-25 billion semiconductor fabrication plant<\/a> near Giga Texas, also known as the Gigafactory<\/a>, in eastern Travis County. Environmentalists warn the project could further strain a persistently drought-stricken region and potentially clash with the city\u2019s long-term water planning efforts.<\/p>\n

\u201cIt\u2019s extremely alarming,\u201d said Paul DiFiore, an environmental attorney who sits on Austin\u2019s Water Forward task force<\/a>. \u201cAll of a sudden, they’re using more water than the vast majority of people in the city.\u201d<\/p>\n

Tesla began construction of the Gigafactory in the summer 2020, with the help of $13.9 million tax rebate<\/a> from Travis County. The factory opened in April 2022<\/a> and has since become one of Austin Water\u2019s largest consumers, with usage rising in a short period of time.<\/p>\n

Environmental Attorney Sarah Faust, who also sits on Austin\u2019s Water Forward Task Force, said that Tesla was granted a service extension request<\/a> from Austin Water, a process that does not require City Council approval. Austin Water said it provides water to only a portion of the Gigafactory, and the company\u2019s property extends across the service boundaries of multiple utility providers.<\/p>\n

By last fall, the factory had produced 500,000 vehicles<\/a> \u2014 a manufacturing process that, Faust noted, requires a significant amount of water.<\/p>\n

In a separate city process first approved in 2018, the city has worked to solidify and refine its 100-year water resource plan known as \u201cWater Forward.\u201d The plan, which was last updated in 2024, is intended to balance water needs against a future of climate change, the possibility of increasingly severe drought and continued growth.<\/p>\n

Faust said the task force charged with updating the plan takes into account large commercial consumers, but \u201cwhen we get new, big users that grow dramatically in a short amount of time, that does cause a little bit more concern.\u201d<\/p>\n

She acknowledged that economic development is important, but said as many Austinites are being asked to conserve<\/a>, the sharp increase in water use raises questions about whether conservation efforts are being applied evenly, or whether large industrial users are operating under different constraints.<\/p>\n

\u201cFrom a policy perspective, from a water planning perspective,\u201d Faust said, \u201cI hope [Austin Water] is utilizing [its tools] to the greatest degree to ensure that as much recycling and reuse is done and that appropriate limits are put on water used for commercial purposes.\u201d<\/p>\n

Austin Current reached out to Tesla to ask what is driving the increase in water use, whether it expects demand to rise and what conservation measures are in place or plans to put in place. The company did not respond before publication, leaving key questions about future water demand unanswered.<\/p>\n

In a statement, Austin Water said it is required to provide water within its service area for any permitted development. Per the city\u2019s Drought Contingency Plan<\/a>, the utility could limit or curtail water usage under emergency conditions.<\/p>\n

Keisuke Ikehata<\/a>, a water treatment expert and associate professor of civil engineering at Texas State University, agreed the increase in water use from 2023 to 2025 \u201cis quite a big jump,\u201d one that underscores the scale of industrial demand entering the region<\/p>\n

\u201cWe really need to be very careful in terms of planning how the industry grows and how our community grows,\u201d he said, \u201cThat is certainly a lot of water.\u201d<\/p>\n

But Tesla\u2019s current water use in Central Texas may be just the start to much larger demand curve.<\/p>\n

New factory could multiply water demand<\/p>\n

In March, Musk announced at Austin\u2019s old Seaholm Power Plant<\/a> plans to build Terafab as part of a joint effort involving SpaceX, Tesla and xAI. The factory would produce chips to power Musk\u2019s vast technology portfolio. When announcing the venture, Musk called it \u201cthe most epic chip-building exercise in history by far.\u201d<\/p>\n

Ikehata said a typical North American semiconductor plant might require one to two million gallons of water a day, or around 350 to 700 million gallons of water annually, a baseline that underscores how water-intensive chip manufacturing can be.<\/p>\n

Reports indicate that at least part of the facility would be built near the Gigafactory in eastern Travis County. But Musk said in an X post last month<\/a> that Terafab would not fully fit on that campus and would require \u201cthousands of acres.\u201d A Travis County commissioner said the court has only recently been made aware of the plans and has not yet received any formal proposal, leaving key details about water sourcing and infrastructure unresolved.<\/p>\n

\u201cIt will be far bigger than everything else combined there,\u201d Musk wrote.<\/p>\n

If the facility lives up to its promise, Ikehata said it could need several more million gallons of water a day \u2014 potentially billions annually \u2014 than a typical semiconductor plant. Those millions of gallons of additional water would push total demand far beyond current levels in the area.<\/p>\n

\u201cThey use a lot of water at their facilities,\u201d Ikehata said. Water \u201cis required to clean all kinds of things that they are manufacturing.\u201d<\/p>\n

Austin Water told Austin Current it has not yet received a request for water service at the proposed facility.<\/p>\n

The water must be extremely pure when cleaning chips, which are exceedingly small and precisely fabricated, he said.<\/p>\n

Those chips are in \u201ccars and satellites and cell phones, we need those chips everywhere,\u201d Ikehata said. \u201cThe tiniest bit of an error can cause a complete catastrophe.\u201d<\/p>\n

Balancing growth against limits<\/p>\n

Ikehata acknowledged an ongoing tension in Central Texas: balancing rapid growth with the reality of a limited water supply, a constraint that becomes more acute as large industrial users expand.<\/p>\n

\u201cI\u2019m very much supportive of economic growth. I’m an engineer. I love development,\u201d he said. \u201cBut I want responsible development\u2026 Responsible water use is very important and has to be carefully evaluated. Stakeholders should be involved, and I’d like to see transparency.\u201d<\/p>\n

Council Member Ryan Alter echoed Ikehata\u2019s sentiment, saying the economic benefits of bringing Terafab to Austin could be significant, particularly as the region competes for major industrial projects.<\/p>\n

\u201cWe want those jobs. We want the economic activity that comes along with that,\u201d Alter said. \u201cBut we also have to balance the environmental impacts.\u201d<\/p>\n

Alter said the key to making the proposal successful in Austin will be strong collaboration between the company and the city, especially as questions about water capacity and long-term supply remain a top concern.<\/p>\n

\u201cI think water is the limiting factor of our city,\u201d he said. Alter said large water users could help offset their impact through reuse, infrastructure improvements or other measures that reduce strain on the system, though those solutions would need to scale alongside demand.<\/p>\n

\u201cI think there are ways where we can work together so that everyone comes out ahead,\u201d he said. \u201cThat’s hopefully the conversation we’re going to have.\u201d<\/p>\n
