New Rules May Limit Austin Water Use

Austin Water is moving toward new rules that could change how some of the city’s biggest customers use water. The proposal is aimed at large-volume commercial accounts, a category the utility defines as existing customers that buy more than 85 million gallons in a fiscal year at a single service address or campus. Austin Water has been tightening conservation policy as drought remains a central planning issue for the city and the Highland Lakes system that supplies much of its water. The timing matters because Austin’s Water and Wastewater Commission is scheduled to meet on Wednesday, May 20, 2026, and its adopted 2026 calendar lists May 28 as the corresponding City Council date. A draft May 28 council agenda was already posted this week, though it said items could still change before final publication. ### Which customers are these rules aimed at? (services.austintexas.gov) Austin Water’s own briefing defines a large-volume customer as an existing commercial customer that purchases more than 85.0 million gallons of water during a fiscal year running from Oct. 1 to Sept. 30 at one service address or campus. The utility says it monitors consumption each year to determine which existing customers cross that threshold. (services.austintexas.gov) That means the proposal is not framed around ordinary household use. It is aimed at the upper end of Austin’s commercial and industrial demand, where a small number of accounts can consume water on a scale far above residential customers. Austin Water has separately said it plans future water-budget billing to address high irrigation use by commercial and multifamily customers.

Austin City Council unanimously approved updated long-term conservation and drought policies on May 2, 2024, but council members and utility leaders said at the time that they expected to revisit the rules and potentially tighten them later. KUT reported that the vote came after criticism from the city’s Water Forward task force, whose members said the plans did not go far enough to protect Austin’s supply. (services.austintexas.gov) Shay Ralls Roalson, Austin Water’s director, told council in 2024 that updated plans were needed so the city could respond if drought conditions worsened. Austin’s November 2024 conservation plan says the city faces “record high temperatures, record low flows into the Highland Lakes, water quality concerns, and continued rapid population growth.” (kut.org) ### Are big industrial users already drawing scrutiny? Tesla’s Gigafactory in eastern Travis County has become a visible example in the debate. Austin Water data cited in an April 14, 2026 report showed Tesla’s annual treated water use rose about 68% from 2023 to 2025, to 556 million gallons, making it the utility’s third-largest customer. (kut.org) Paul DiFiore and Sarah Faust, both members of Austin’s Water Forward task force, told that report that fast-growing industrial demand can strain planning assumptions. Their comments were tied to broader concerns about how Austin applies conservation limits while large users expand. ### What could the new approach look like? Austin Water has not, in the material surfaced publicly so far, laid out the full final text of the proposed rule changes. (insurancejournal.com) But the available city documents point in a consistent direction: tighter oversight of large-volume accounts and broader use of water-budget style limits for high-use commercial properties. Austin’s conservation framework already ties long-range planning to Water Forward, the city’s 100-year integrated water resource plan. That plan is designed to balance growth, drought risk and climate pressures, and city documents describe conservation, reuse and efficiency as core tools. ### When will Austinites know more? May 20, 2026 is the next scheduled regular meeting date for the Water and Wastewater Commission, and May 28, 2026 is the linked council date on the commission calendar. (services.austintexas.gov) Those two meetings are the clearest public milestones for when the proposal could move from staff briefing to formal city action. Austin posts commission and council materials through its public records and agenda systems, where the large water user overview and related meeting documents have appeared. (austintexas.gov) The final agenda for May 28 will determine whether City Council takes up the item this month. (services.austintexas.gov) (services.austintexas.gov)
