Are misting systems allowed during drought water restrictions?

Usually yes for a home patio, and often no for a business once restrictions tighten. In the five utility codes on this page, residential misting keeps running until the severe or emergency stage, while commercial misting is limited earlier: Las Vegas allows it for human comfort only from May through August in every year, and Georgetown, Texas cuts commercial patio misters to evening hours from Stage 2. The rule that applies to you is the one in your own utility's plan at its currently declared stage, and those stages change within a season.

Two opposite answers circulate. One says misting is banned in a drought because it sprays water into the air. The other says a mister uses so little water that restrictions never touch it. Both are wrong as general rules. Drought plans restrict by named use and by stage, and a mister is legal or not depending on whether the words in the plan catch it at the stage your utility has declared.

What do real drought plans say about misters?

The table quotes or closely paraphrases each code. We read every source on September 29, 2026; each row carries the date of the text it reports. Stages are declared by the utility, so the row that applies to you is the one matching today's declared stage, not the most severe row.

Misting rules by utility and drought stage (sources read September 29, 2026)

Utility	Stage or condition	Home misters	Commercial misters	Text dated
Las Vegas Valley Water District, NV	Standing conservation measures (no stage)	"Allowed with no restrictions"	For human comfort, allowed only in May, June, July and August	Page undated; read 2026-09-29
Bullhead City, AZ	Tier 2 Colorado River shortage, from January 1, 2023	Not named	Banned: "operation of outdoor misting systems used to cool public areas"	Code through Supp. 69 (August 1, 2023)
Bullhead City, AZ	Tier 2 and Tier 3, current code	Not named	Not named: the misting item was removed by Ord. No. 2023-22	Amended September 5, 2023; code through March 17, 2026
Lakeway MUD, TX	Stage 1 (mild)	Allowed	Allowed	Stage 1 in effect from July 7, 2025
Lakeway MUD, TX	Stage 3 (severe)	Only on a recirculating system	Only on a recirculating system	Plan approved April 10, 2024
Lakeway MUD, TX	Stage 4 (emergency)	No: essential use only (bathing, drinking, cooking)	No: essential use only	Plan approved April 10, 2024
Georgetown, TX	Stage 1	Not named	Not named	Ord. No. 2023-20
Georgetown, TX	Stage 2	Not named	Patio misters only 4:00 p.m. to midnight	Ord. No. 2023-20
Georgetown, TX	Stage 3	Not named	Patio misters only 4:00 p.m. to 8:00 p.m.	Ord. No. 2023-20
Georgetown, TX	Stage 4 (emergency)	Banned: "may not operate a patio mister"	Banned	Ord. No. 2023-20
Colorado Springs Utilities, CO	Stages I to III	Not named	Not named	Ord. No. 19-99, effective December 26, 2019
Colorado Springs Utilities, CO	Stage IV (critical)	Banned: "all outside use of water is prohibited"	Banned	Ord. No. 19-99, effective December 26, 2019

"Not named" means the stage's text does not mention misters. It does not guarantee a mister is fine: a general waste-of-water rule still applies, and a line with leaking fittings that sends water onto a sidewalk breaks those rules in any stage. Fixing drips with anti-drip nozzles is cheap insurance.

The Bullhead City ban that no longer exists

Bullhead City is still widely cited as a place where misters are banned, and for eight months that was true. From January 1, 2023, a federally declared Tier 2 shortage triggered Section 8.14.050 of the city code, and item 5 on its list prohibited "operation of outdoor misting systems used to cool public areas." The code as published through August 1, 2023 still carries that item. The current code lists only four Tier 2 prohibitions (leaks not fixed within 72 hours, hosing buildings or pavement, washing vehicles without a shut-off nozzle, and decorative fountains without recirculation), and its history note cites Ord. No. 2023-22 of September 5, 2023. Tier 3 does not add it back. Pages repeating the 2023 news are describing a rule that the city repealed the same year.

Which words in an ordinance catch a mister?

Few plans use one standard term, so search the text for all of these. The phrase decides who is covered, and a clause that looks close may not reach your equipment at all.

• "Misting system" or "patio mister." A direct hit. Lakeway MUD, Las Vegas and Georgetown all name the equipment. Read the rest of the sentence for limits on who it covers: Georgetown's Stage 2 and 3 limits apply only "at a commercial facility."
• "For human comfort" or "personal comfort." Las Vegas uses "for human comfort" to define the commercial misting it restricts. Colorado Springs Stage III limits water "for cooling or air conditioning spaces for the purpose of personal comfort" to what keeps air at 78°F or above, a clause built around thermostats in buildings. Whether it reaches an open-air patio mister is a question to put to the utility, not one to guess.
• "Water features." This one splits. Lakeway MUD's plan lists misting systems among outdoor water features, next to fountains, splash pads and water slides. Colorado Springs defines a water feature as "any fountain or waterfall used for decorative or aesthetic purposes," which does not describe a cooling mister, so its Stage II and III water feature bans do not name misters. Las Vegas treats fountains and misters in separate rules.
• "Cool public areas." Bullhead City's repealed wording aimed at misters serving public spaces, not a private backyard.
• "All outside use of water" or "essential use only." Blanket emergency language catches everything outdoors, misters included, whether or not the word appears.
• "Recirculating." Lakeway MUD's Stage 3 lets water features run only on a recirculating system. A mister sprays water that is meant to evaporate, so none of it returns to be reused. Unless the utility accepts your setup in writing, plan on Stage 3 meaning off.

How much water does a residential mister use per hour?

About 24 gallons an hour for a typical high-pressure patio line: 16 nozzles of 0.012 in at 1,000 psi, each flowing about 1.5 GPH. Over a 6-hour afternoon that is 144 gallons. The figure scales directly with nozzle count, orifice size and hours, so put your own numbers in the water use and cost calculator before you decide whether the savings a restriction asks for are worth arguing about.

Misting water use at common sizes (planning flows at 1,000 psi unless noted)

System	Gallons per hour	6-hour day	60 days at 6 hours a day
12 low-pressure hose nozzles at an assumed 1.5 GPH	18	108	6,480
16 nozzles, 0.008 in (1.0 GPH)	16	96	5,760
16 nozzles, 0.012 in (1.5 GPH)	24	144	8,640
20 nozzles, 0.012 in (1.5 GPH)	30	180	10,800
30 nozzles, 0.012 in, restaurant patio	45	270	16,200

For scale, Lakeway MUD's drought surcharges start in Stage 2 and only affect customers using above 30,000 gallons per two-month bill cycle. A 16-nozzle home line run 6 hours every day of that cycle uses 8,640 gallons, a little under 30% of that threshold on its own. A restaurant patio is a different order: the 30-nozzle layout in our restaurant and commercial patio guide uses about 450 gallons on a 10-hour service day, which is why commercial misting is where plans restrict first.

Orifice size is the fastest legal reduction. Swapping 0.012 in nozzles for 0.008 in cuts flow by one-third at the same pressure, as the orifice size and flow table shows, and cycling the mist 50% on, 50% off halves it again. The misting system cost guide works those two changes through a full season.

How do you check the rule for your own utility?

Ten minutes with the plan answers it. Do this at the start of each season and again whenever your utility announces a stage change.

1. Find the plan and the declared stage. Search your utility's site for "drought contingency plan," "water shortage ordinance" or "conservation measures." The plan lists every stage; a separate notice or irrigation page says which one is in force today.
2. Search the text for each trigger word. Mist, mister, misting, water feature, cooling, comfort, outdoor use, recirculat, essential. Read every hit in the stage you are in and every stage below it, because most plans add restrictions on top of earlier stages.
3. Check who each clause covers. Commercial facility, public area, residential or all customers. A restaurant and a homeowner under the same utility can face different rules at the same stage.
4. Note the conditions. Permitted months, permitted hours, recirculation, or an outright ban.
5. Program the limit into the controller. A Georgetown restaurant in Stage 3 can mist from 4:00 p.m. to 8:00 p.m.; set a timer so staff cannot forget. Controllers, timers and humidistats covers the hardware, and a humidistat cutoff also trims runtime on days the mist barely cools (the cooling potential calculator shows which days those are).
6. Ask in writing when the words are unclear. Email the conservation office with the clause and your equipment, and keep the reply with its date. That settles questions like whether a tank-fed misting fan counts.

When does this answer stop applying?

Every row in the table is dated because every row expires. Utilities move between stages within a single summer: Lakeway MUD's irrigation page recorded a return to Stage 1 from July 7, 2025, after the July 4 weekend flood changed combined storage in Lakes Buchanan and Travis, and the district says it updates its drought plan every five years as a state requirement. Bullhead City rewrote its Tier 2 list eight months after it took effect. A mister that is legal in June can be banned in August under the same plan.

Three things this page does not cover. First, the five utilities here are examples chosen because their codes could be read in full; they are not a survey, and your own plan may treat misters in a way none of these do. Second, homeowner association rules, commercial building leases and health department conditions can restrict a mister that the water code allows. Third, adding anything other than water to a mister is a separate legal question, covered in mosquito misting and the law. For design and placement once you know you can run the system, start from the patios hub.
