New Rules Target Austin's Big Water Users

Austin officials are moving toward tighter water-conservation rules for the city’s biggest commercial and institutional customers as data centers, chip manufacturing and other high-demand facilities expand in Central Texas. A May 18 briefing to the City Council’s Climate, Water, Environment and Parks Committee focused on new ways to track and regulate large-volume users, according to the city agenda and local coverage of the meeting. Austin Water has said the effort is part of its broader Water Forward planning, which includes conservation, reuse and drought-response measures. Austin remains under Conservation Stage watering restrictions that took effect on Sept. 2, 2025, according to the utility. ### Which customers are Austin officials targeting? Austin leaders are looking at “large-volume users,” a category city officials discussed in connection with data centers and semiconductor manufacturing during the May 18 committee meeting. KVUE reported that council members said growth in those sectors could put pressure on Austin’s water supply. Austin Water has not publicly framed the proposal as a citywide cut for all businesses. The discussion instead centers on the biggest nonresidential users — the customers whose demand can rise quickly with new industrial development and large cooling loads. ### Why is the city focusing on them now? Austin Water’s long-range planning documents already call for stronger conservation and more active management of customer demand. The city’s 2024 Water Conservation Plan says Austin used roughly the same amount of water in 2023 as it did in 2011 despite population growth, and it ties future reliability to continued conservation and new supply strategies. The pressure from data centers has become more visible this year. A May 6 report highlighted by the University of Texas at Austin said data centers could account for 3% to 9% of Texas water use by 2040, depending on growth and operating practices. That report called for more transparency around industry water demand. ### What kinds of rules are on the table? Austin officials have described the effort as a push to better track and regulate water use by the largest customers. Public city materials available so far do not spell out a final ordinance language, gallon threshold or penalty structure. Austin Water’s recent planning and budget documents point to the kinds of tools the utility is already considering more broadly: water-use budgeting, tighter irrigation controls, customer-side leak detection through smart-meter data, expanded conservation incentives and more reuse infrastructure. The city also adopted earlier Water Forward-related code changes in 2021 and 2024 covering reclaimed water, benchmarking and onsite water reuse for some developments. ### Is this tied to drought rules already in effect? Austin Water says the city is in Conservation Stage water-use restrictions, the least restrictive drought-related stage now in effect, after those rules began on Sept. 2, 2025. Even at that level, the utility limits outdoor watering schedules and urges businesses to fix leaks, audit water-using equipment and align irrigation with current restrictions. The new large-user discussion goes beyond ordinary watering schedules. City officials are examining whether the biggest customers should face additional monitoring or limits during drought and whether new high-demand projects should be subject to clearer conservation requirements before shortages deepen. ### Where did this show up in the city process? The May 18 Climate, Water, Environment and Parks Committee meeting included Austin Water briefings, and local television coverage said council members used that session to discuss large-user regulation. The city’s Water and Wastewater Commission agenda for May 20 separately listed a “Large Customer Usage and Conservation Presentation.” Austin’s online meeting records show the committee is chaired by Council Member Ryan Alter, with Council Member Paige Ellis as vice chair. Austin Water Director Shay Ralls Roalson was listed as a presenter for another water briefing at the May 18 committee meeting. ### What happens next? The next concrete step in public city records was the May 20 Water and Wastewater Commission review of the “Large Customer Usage and Conservation Presentation.” Austin City Council’s May 21 regular meeting agenda was also posted, though the available agenda text did not clearly show a final action on a new large-user ordinance. Any binding rule change would need to move through Austin’s public meeting process with posted backup documents and, if required, council action.
