Austin Water is in Conservation Stage for 2026. Automatic in-ground irrigation may run one designated day per week, before 10 a.m. or after 7 p.m. Hose-end sprinklers and drip may run up to two designated days per week in the same hours. Hand-watering and tree bubblers are allowed any time. Your day is set by your address.
Whether your yard is in Zilker, Hyde Park, Mueller, Circle C, or out toward the suburbs, the same rules apply, and watering on the wrong day or in the wrong window can bring a fine. Below is how to find your day, what the stage allows, and a month-by-month plan to keep a Central Texas lawn healthy on very little water.
Austin watering rules in numbers
- 1 day per week for automatic in-ground irrigation systems (Austin Water, Conservation Stage).
- 2 days per week for hose-end sprinklers and drip irrigation (Austin Water, Conservation Stage).
- Before 10 a.m. or after 7 p.m. – the only hours either track may run.
- Any time, no day limit for hand-held watering and tree bubblers.
- 3.5 to 4 inches mowing height for St. Augustine through peak summer, to shade roots between watering days.
- 2 to 3 shorter runs per zone (cycle-and-soak) so water absorbs into tight, caliche-heavy soil instead of running off.
Under Conservation Stage, how often you can water depends on the equipment you use:
- Automatic in-ground irrigation systems: one designated day per week, and only before 10 a.m. or after 7 p.m.
- Hose-end sprinklers and drip irrigation: up to two designated days per week, same hours.
- Hand-held watering and tree bubblers: allowed any time, no day or hour limit. In a Texas summer this is how you keep live oaks and beds alive when the lawn cannot be watered.
Your designated day is based on your address. Austin Water does not publish the full address-to-day map in its notices, so look yours up at austinwater.org under “Find Your Watering Day” and set your controller to match. The midday block matters: water applied between 10 a.m. and the evening loses a large share to evaporation before roots ever use it.
What the wrong day costs you
These restrictions are enforced, not suggested. Watering outside your assigned day or the allowed hours can trigger a violation, and repeat violations escalate. Beyond any penalty, running an inefficient system in the heat simply wastes money, because so much of a midday cycle evaporates. The households that pour the most onto thirsty turf are the ones paying the most for the least result.
Newly installed landscapes need more water to establish than the once-a-week rule allows. Hand-watering is permitted any time, which covers new trees, shrubs, and beds with a slow soak at the base. Austin Water also offers a variance process for new or replacement landscapes on an automatic system. If you are installing this season, apply through Austin Water for the establishment variance and time the project so the young plants are not fighting both the heat and the schedule.
Austin lawns are warm-season grasses, mostly St. Augustine and Bermuda, so the calendar follows their growth.
- Spring (Mar to May): as the lawn greens up, drop mowing to a clean first cut, apply a pre-emergent early to stop crabgrass, and fertilize only after full green-up. Check the irrigation system for broken heads before the heat arrives.
- Summer (Jun to Aug): peak heat and peak stress. Mow high (St. Augustine at 3.5 to 4 inches) to shade roots, water deep and infrequent on your assigned day, and scout for chinch bugs and grubs, which explode in the Central Texas heat.
- Fall (Sep to Nov): the recovery window. Fertilize to rebuild roots before dormancy, aerate compacted areas, and address any thin spots. This is also the best season for new installs, hardscape, and design work.
- Winter (Dec to Feb): the lawn goes largely dormant and needs little water. Use the cool months for planning, bed cleanup, tree work, and any renovation you want green by spring.
An Austin yard built for one-day watering
Following the schedule is the floor. The yards that stay healthy on one day a week are the ones designed for it. Cycle-and-soak is the most useful habit here: split each zone into two or three shorter runs so water absorbs into our tight, often caliche-heavy soils instead of running off. Swapping old spray heads for high-efficiency rotary nozzles, and moving beds to drip, cuts waste sharply. Converting the hardest-to-water strips to native and adapted plantings removes the thirstiest turf entirely, and Austin Water offers WaterWise rebates that can offset part of a conversion.
Know whether you are on the one-day (auto) or two-day (hose-end and drip) track, look up your assigned day, keep watering out of the midday window, lean on hand-watering to protect trees, and match your design to Central Texas. Do that and your lawn can look good all season without risking a violation.
If you would like a hand setting a controller to your legal day, fixing irrigation efficiency, or planning a lower-water yard, the Austin Pro Landscape Team works with these exact conditions every day.
Rules current as of July 2026. Austin’s conservation stage can change with reservoir levels; confirm the active stage at austinwater.org before relying on this schedule.
Austin watering rules: common questions
What is my Austin watering day?
Your watering day is assigned by your service address, not by your zip code or neighborhood. Austin Water does not publish the full address-to-day map in its notices, so look yours up under “Find Your Watering Day” at austinwater.org and set your irrigation controller to match that day.
What hours can I water in Austin?
On your designated day, watering is allowed before 10 a.m. or after 7 p.m. The midday block is excluded because water applied between 10 a.m. and the evening loses a large share to evaporation before roots ever use it. Hand-watering and tree bubblers are exempt from the hour limits.
What stage is Austin Water in for 2026?
Austin Water is in Conservation Stage for 2026. Under this stage automatic irrigation systems run one day per week and hose-end sprinklers and drip run up to two days. The stage can change with reservoir levels, so confirm the active stage at austinwater.org before relying on any schedule.
Can I hand-water on any day in Austin?
Yes. Hand-held watering and tree bubblers are allowed any day and any hour under Conservation Stage. In a Central Texas summer this is how live oaks, new trees, shrubs, and beds stay alive when the lawn itself can only be watered on its assigned day.
Can I water a new lawn more often in Austin?
Newly installed landscapes need more water to establish than one day a week allows. Hand-watering covers new trees, shrubs, and beds with a slow soak at the base, and Austin Water offers a variance process for new or replacement landscapes on an automatic system. Apply through Austin Water before installing.
What happens if I water on the wrong day in Austin?
These restrictions are enforced, not suggested. Watering outside your assigned day or the allowed hours can trigger a violation, and repeat violations escalate. Beyond any penalty, an inefficient midday cycle wastes money, because much of the water evaporates before the lawn uses it.
Rules current as of August 2026. Austin Water can change the conservation stage with reservoir levels; confirm the active stage at austinwater.org before relying on this schedule.
