Austin TX Water Restrictions 2026

Current water restrictions in Austin, Texas

Austin is under Conservation Stage restrictions, limiting outdoor irrigation with automatic systems to 1 day per week on an address-assigned schedule — and these rules are permanent, year-round, regardless of season.

Austin Water administers the city's outdoor watering rules under its Water Conservation Code. The Conservation Stage returned on September 2, 2025, following a period when the Highland Lakes — Lake Travis and Lake Buchanan on the Colorado River — had recovered enough to step back from more severe restrictions. Even so, Austin Water has embedded the 1-day-per-week automatic irrigation limit as a standing year-round baseline, meaning no trigger event is required to maintain it.

The Highland Lakes are Austin's primary municipal water supply, and their storage levels directly drive stage escalations. When combined storage falls below defined thresholds, Austin Water can move to Stage 1, Stage 2, or Stage 3 — each progressively more restrictive. The current Conservation Stage sits below Stage 1 in severity but is still mandatory, not voluntary.

Texas is experiencing mixed drought conditions statewide, with neighboring cities under significantly stricter rules: Pflugerville has declared a Stage 3 Emergency, and San Antonio's Edwards Aquifer hit critically low levels, triggering that city's first Stage 3 restrictions in SAWS's 30-year history. Austin's situation is comparatively stable, but the year-round mandatory schedule reflects how vulnerable Central Texas water supplies remain.

Practically speaking: if your assigned watering day is Wednesday, you can run your irrigation system on Wednesday morning before 10 a.m. You cannot run it on Thursday, Friday, or any other day. Hand watering with a shut-off nozzle, however, is allowed any day at any time — so watering a vegetable garden or a newly planted tree by hand on a Wednesday afternoon is fully permitted. Drip irrigation is also unrestricted.

When can you water in Austin?

Austin Water assigns your specific watering day based on your street address. To find your day, use the official lookup tool at austintexas.gov/water/find-your-watering-day or call 512-972-0000. You enter your address and the system returns your assigned day — no guesswork. The watering window itself runs overnight into the morning (midnight to 10 a.m.) and again in the evening (7 p.m. to midnight), intentionally avoiding the midday heat when evaporation loss from Austin's hot sun would waste the most water.

Multi-family residential properties and commercial accounts are subject to the same one-day-per-week automatic irrigation limit. Large commercial accounts with dedicated irrigation meters should confirm their assigned day through Austin Water's business services line, as scheduling can differ slightly from residential assignments on the same block. Homeowners' associations managing shared irrigation systems must also comply with the same address-based assignment for the property they service.

Austin's urban tree canopy includes species that are stressed by drought and benefit from targeted watering on non-irrigation days. Live oak (Quercus fusiformis), the dominant street and yard tree across Austin, is vulnerable to oak wilt when stressed; deep, infrequent watering via tree bubbler is recommended over sprinkler spray. Texas mountain laurel (Sophora secundiflora), common in newer Austin landscaping, establishes slowly and needs supplemental water in its first two summers. Mexican sycamore (Platanus mexicana), planted along riparian corridors and newer developments in the Austin area, has high water demand during establishment. All three can be watered by hand or drip on any day under current rules.

Penalty schedule for water violations

Austin Water enforces watering restrictions through a combination of methods. The city has deployed smart meters across much of its service area — these Advanced Metering Infrastructure (AMI) devices track water usage in hourly intervals and can flag unusual overnight or midday consumption that may indicate unauthorized irrigation. Compliance officers also conduct field patrols, particularly during early morning hours when violations are most likely to occur. Neighbor complaints routed through Austin 311 (via the app, website, or phone) are a significant source of violation reports; Austin 311 logs and routes these to Austin Water's enforcement staff, typically within one to two business days.

If you receive a notice of violation, Austin Water's Conservation program offers a pre-penalty review process. You can contact the Conservation department at 512-972-0000 to discuss the circumstances before a formal citation is issued, particularly for first-time violations that may result from a malfunctioning irrigation controller rather than intentional noncompliance. Fixing a documented equipment failure promptly and reporting it can weigh in your favor during review.

Other outdoor water rules

Austin Water's Conservation Stage restrictions extend beyond lawn irrigation. The following activities carry specific rules or prohibitions during the current stage:

• Residential car washing: Allowed only with a hand-held hose equipped with a positive shut-off nozzle, or at a commercial car wash that recycles water. Leaving a hose running unattended is prohibited.
• Pool and hot tub filling: Filling a new pool or spa is allowed but must use a licensed plumber or pool contractor who can verify compliance. Topping off an existing pool to compensate for evaporation is permitted — Austin's intense summer heat makes evaporation loss substantial — but draining and refilling should be minimized.
• Fountains and decorative water features: Recirculating fountains that do not discharge water to a drain are allowed. Single-pass systems that continuously discharge to a sewer or storm drain are prohibited.
• Pressure washing: Hard surface cleaning with a pressure washer is permitted when necessary for health or safety, but continuous flow without a shut-off device is a violation.
• Construction and dust control: Contractors operating within Austin city limits must use recycled or reclaimed water for dust suppression where available. Potable water use for construction grading dust control is restricted.
• Restaurant water service: Under Austin Water's stage rules, restaurants are required to serve water only upon customer request — not automatically to every table.

Where Austin's water comes from

Austin's municipal water supply comes almost entirely from the Colorado River as stored in the Highland Lakes — a chain of reservoirs in the Texas Hill Country managed by the Lower Colorado River Authority (LCRA). The two reservoirs that matter most for Austin's supply are Lake Travis and Lake Buchanan. Lake Travis, immediately upstream of Austin near Lago Vista, is the primary storage reservoir; Lake Buchanan, further upstream in Llano and Burnet counties, provides backup storage. Combined, they hold over 2.6 million acre-feet at full capacity.

Austin Water operates two major surface water treatment plants: the Davis Water Treatment Plant on the Colorado River near Tom Miller Dam, and the Ullrich Water Treatment Plant in West Austin. Together these facilities have a combined treatment capacity of over 285 million gallons per day. Raw water travels from Lake Austin — the smaller reservoir immediately behind Tom Miller Dam — into the treatment plants before distribution across Austin's service area.

Unlike San Antonio, which draws from the Edwards Aquifer, Austin does not rely on aquifer withdrawals as a primary supply. The Edwards Aquifer does underlie parts of western Travis County and is critical to the Barton Springs system, but Austin Water is a surface water utility. This distinction matters during regional drought: when the Highland Lakes drop, Austin feels it directly. LCRA's Water Management Plan governs how water is allocated between Austin, downstream agricultural users, and environmental flow requirements for the lower Colorado River. When combined Lake Travis and Lake Buchanan storage falls below 900,000 acre-feet, LCRA begins curtailing interruptible agricultural water rights, which can affect political pressure on Austin's own conservation requirements.

Austin's ongoing growth — the metro area is one of the fastest-growing in the United States — is putting measurable pressure on Highland Lakes storage, making the year-round Conservation Stage not just a drought response but a long-term supply management strategy.

Can your HOA fine you for a brown lawn?

Texas Property Code § 202.007 prohibits a property owners' association from enforcing any deed restriction, rule, or requirement that prevents an owner from implementing water-efficient landscaping or allowing a lawn to go dormant or die back during a water shortage. Specifically, an HOA in Austin cannot fine you, threaten enforcement action, or require corrective landscaping maintenance for a lawn that browns out because you are complying with Austin Water's mandatory Conservation Stage watering schedule.

This protection applies during any period when a governmental entity — such as Austin Water — has imposed mandatory water use restrictions. The law was designed precisely for situations like Austin's year-round 1-day-per-week limit, where following the city's rules makes it physically impossible to keep a Bermuda or St. Augustine lawn perpetually green. The HOA cannot demand that you overwater to meet an aesthetic standard that contradicts a binding municipal order.

If your HOA sends a violation notice about lawn appearance during Austin Water's Conservation Stage, you can respond in writing. Here is a template:

"This notice is to inform you that the condition of my lawn is a direct result of my compliance with Austin Water's mandatory Conservation Stage restrictions, which limit automatic irrigation to one assigned day per week. Under Texas Property Code § 202.007, a property owners' association may not enforce any requirement that necessitates watering in excess of what is permitted under a governmental water use restriction. I am in full compliance with Austin Water's current mandatory schedule. Please confirm in writing that this matter is closed."

If the HOA continues enforcement action after receiving written notice, you can file a complaint with the Texas Real Estate Commission, which has jurisdiction over HOA management company conduct, or seek relief through a Travis County Justice of the Peace court.

How to manage your lawn during drought

Austin sits in the warm-season grass zone, where summer temperatures regularly exceed 100°F and cool-season grasses cannot survive as perennials. The grasses you are likely maintaining — or choosing between — are all heat-tolerant species with different drought tolerances:

Austin's climate presents a specific challenge: intense summer heat (July average high near 97°F), clay-heavy soils in many neighborhoods — particularly the Houston Black clay and Austin clay series common in central and south Austin — and episodic drought punctuated by heavy rain events. Clay soils require slow, deep watering to penetrate without runoff; running your irrigation system for the full allowable window on your one assigned day, rather than splitting into shorter cycles, helps water reach root depth. Calibrate your system to apply no more than one inch per week — Austin Water recommends a tuna-can test to measure output.

In Austin's summer heat, St. Augustinegrass under Conservation Stage watering will likely show stress and partial die-back, especially in south- and west-facing exposures. Rather than fighting this, consider raising mower height to 3.5–4 inches, which reduces moisture loss from the soil and helps the remaining turf shade its own root zone. Many Austin homeowners are transitioning stressed lawn areas to native ground covers such as Habiturf (a native seed blend developed by the Lady Bird Johnson Wildflower Center specifically for Central Texas), which requires far less irrigation once established.

Questions residents are asking

What is my assigned watering day in Austin?

Your day depends on your specific street address. Austin Water maintains an online lookup tool at austintexas.gov/water/find-your-watering-day — enter your address and it returns your assigned day instantly. You can also call Austin Water directly at 512-972-0000 during business hours. Do not assume your day based on a neighbor's schedule; addresses on the same block can be assigned different days.

Can I water more than once a week if my lawn is visibly dying?

No. Under the mandatory Conservation Stage, automatic irrigation systems are restricted to one assigned day per week regardless of lawn condition. There is no hardship waiver for aesthetic lawn damage. However, you can water individual stressed plants, trees, or garden beds by hand with a shut-off nozzle on any day at any time — this exemption is meaningful if you are trying to save a newly planted tree or vegetable garden rather than broad turf areas.

When did Austin return to Conservation Stage, and what changed?

Austin Water returned to Conservation Stage on September 2, 2025, after the Highland Lakes — Lake Travis and Lake Buchanan — recovered sufficient combined storage to step back from more restrictive Stage conditions. The Conservation Stage is Austin's baseline year-round mandatory level, meaning it does not expire; it remains in effect until Austin Water formally declares a return to non-restricted status, which would require sustained Highland Lakes recovery well above current thresholds.

Does Austin Water use smart meters to catch watering violations?

Yes. Austin Water has deployed Advanced Metering Infrastructure (AMI) smart meters across much of its service area. These meters transmit hourly usage data, which allows Austin Water's conservation staff to identify accounts with water flow during prohibited hours — for example, an automatic irrigation system running at noon on a non-assigned day. Smart meter data can be used as evidence in a violation proceeding. You can also access your own hourly data through Austin Water's My ATX Water customer portal to audit your irrigation system's behavior.

Can I wash my car at home under current Austin restrictions?

Yes, with conditions. You must use a hand-held hose with a positive shut-off nozzle so water flows only when you are actively rinsing. Leaving a running hose unattended while washing a vehicle is prohibited. Alternatively, commercial car washes that recycle and reclaim wash water are unrestricted and are often the more water-efficient option per vehicle wash.

What rebates does Austin Water offer for reducing outdoor water use?

Austin Water runs several active rebate and incentive programs. The WaterWise Landscape Coupon program offers discounts on drought-tolerant plants purchased from participating nurseries. The Irrigation Upgrade Rebate provides reimbursement for installing WaterSense-labeled smart irrigation controllers. Austin Water also partners with the Lawn Care Replacement Program, which offers rebates per square foot for replacing water-intensive turf with approved drought-tolerant or native landscaping. Amounts and eligibility change periodically; current program details and applications are available at austintexas.gov/waterconservation or by calling 512-972-0000.

Are hose-end sprinklers treated the same as automatic irrigation systems?

No — they are treated slightly more leniently. Hose-end sprinklers (portable sprinklers attached to a garden hose, operated manually) are allowed 2 days per week under Conservation Stage rules, compared to the 1-day-per-week limit for automatic in-ground irrigation systems. The same allowed hours apply: midnight to 10 a.m. and 7 p.m. to midnight. If you are using a hose-end sprinkler, you still cannot operate it during the prohibited midday window.

My neighbor is running their sprinklers every day. How do I report it?

File a complaint through Austin 311 — available via the Austin 311 app, the website at austin311.gov, or by calling 3-1-1 within Austin city limits. Select "Water Conservation Violation" as the category. Include the address, the date and time you observed the violation, and whether it was an in-ground automatic system or a hose-end sprinkler. Austin Water's conservation enforcement staff review 311 complaints and typically conduct a site visit within one to two business days of a report.

What days can I water my lawn in Austin?

Assigned day by address Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What are the fines for watering violations in Austin?

First offense: Up to $1,000 per violation. Repeat violations: Up to $1,000 per violation. Contact Austin Water for the full enforcement schedule.

When will water restrictions end in Austin?

Current Conservation Stage restrictions are in effect through Year-round. Monitor https://www.austintexas.gov/water/find-your-watering-day for the latest status.

Can I hand water during Austin water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with Austin Water.
