If you’re asking what your watering days are, the answer comes from your local water utility, and it depends on your street address and whatever drought stage is currently in effect. Most providers assign days using the last digit of your address, then shift the schedule tighter or looser as conditions change. Outdoor irrigation accounts for roughly 30 percent of a typical household’s water use and can climb to 70 percent in hot or dry climates, which is why nearly every utility restricts when sprinklers can run.1US EPA. How We Use Water Finding your exact days takes about two minutes once you know where to look.
How Utilities Assign Watering Days
The common setup splits properties by the last digit of the street address. The simplest version is even and odd: even-numbered addresses water on certain days, odd-numbered addresses on others. Some utilities break it down further, pairing each final digit (0–1, 2–3, 4–5, and so on) with a single designated day. The goal is to spread demand across the week so water pressure stays stable.
A smaller number of jurisdictions assign days based on which side of the street your property sits on, north/south or east/west. It’s worth checking if your utility’s schedule doesn’t match a simple even/odd pattern.
Your assigned days aren’t fixed. They shift whenever the regional water authority moves to a different conservation stage. At the lowest restriction levels, you might get two or three watering days per week. At moderate stages, that often drops to one. During severe drought, some authorities eliminate outdoor irrigation entirely, including hand watering, drip systems, and bucket watering.
How to Look Up Your Specific Days
Start with your water utility’s website. Look for the Public Works or Water Conservation page, where most providers post the current schedule along with any active drought stage. Many urban utilities offer an address-lookup tool: type in your street address and it returns your exact watering days and allowed times. That saves you from reading code tables yourself.
If you can’t find it online, check your most recent water bill. Utilities frequently print the schedule on bill inserts or include a direct link. You can also call your water district’s customer service line. Staff can confirm your assigned days, tell you which drought stage is in effect, and flag recent changes.
For regional context, the U.S. Drought Monitor publishes a weekly map showing drought intensity by county. It won’t tell you your watering day, but it gives you advance warning when restrictions are likely to tighten.2US Drought Monitor. Current Map
What Hours You Can Water
Even on your allowed day, you probably can’t water whenever you want. Most ordinances prohibit irrigation during the hottest hours, typically between 10:00 a.m. and 6:00 p.m., because water sprayed in midday heat evaporates before it reaches roots. Some utilities set slightly different windows, such as before 9:00 a.m. or after 4:00 p.m., so check your local rules rather than assuming the 10-to-6 standard applies. The EPA’s WaterSense program recommends watering during cooler hours as one of the most effective ways to reduce outdoor water waste.3US EPA. Start Saving
When the Day-of-Week Rule Doesn’t Apply
Rigid schedules don’t always cover every type of watering. Most jurisdictions carve out exceptions for methods that use water more efficiently than a standard sprinkler.
Hand Watering and Drip Systems
Hand watering with a hose that has a shut-off nozzle is typically allowed any day, sometimes still with time-of-day limits in place. The nozzle requirement matters: the hose must stop flowing when you release the trigger. Bucket watering usually falls under the same exemption.
Drip irrigation and micro-spray systems are often exempt from day-of-week restrictions altogether because they deliver water directly to root zones with minimal waste. If you’ve installed drip, check whether your utility requires registration or a meter tag to confirm the exemption.
Smart Irrigation Controllers
A growing number of municipalities exempt properties using EPA WaterSense-labeled smart controllers from standard schedules. These controllers adjust watering based on weather data, soil moisture, and plant type, and often use less total water than a two-day-a-week manual schedule would.4US EPA. WaterSense Labeled Controllers Where this exemption exists, the utility usually requires you to register the controller before you water outside your assigned days.
Vegetable Gardens
Home food gardens often get broader watering windows than ornamental lawns, particularly during early drought stages. The typical rule allows vegetable gardens to be watered any day as long as you use a hand-held hose, drip, or another efficient method. At more severe drought stages, this exemption may narrow or disappear.
New Sod, Seed, and Plantings
Fresh landscaping needs water every day to survive, which conflicts with once- or twice-a-week schedules. Most utilities handle this with a temporary variance or permit that allows daily watering for a set number of days, commonly 30 to 60 depending on the jurisdiction. The first half of the window usually permits daily irrigation, stepping down to a few days per week after that.
You generally need to apply for the variance before or shortly after installation. Watering a new lawn every day without the permit in hand can draw the same fines as any other violation, even when the plants genuinely need the water.
Rules That Apply Every Day
Separate from the day-of-week schedule, most water conservation ordinances include a year-round prohibition on water waste. You can be cited even on your allowed watering day if water is pooling on pavement, flowing into gutters, or running down storm drains. The standard is whether water is leaving your property or landing where it serves no irrigation purpose.
Property owners are also expected to maintain irrigation equipment in working order. A broken sprinkler head spraying the sidewalk, a leaking valve, or misdirected spray patterns all count as violations in most jurisdictions. A single broken head can waste hundreds of gallons per cycle without you noticing until the bill arrives.
What a Violation Costs
Enforcement typically starts with a warning for a first offense, then escalates. First-violation fines across major U.S. cities generally range from $100 to $250, with repeat offenses climbing to $500 or more. A few cities impose fines as high as $2,000 for persistent violations. Some jurisdictions skip the monetary penalty for a first offense and issue a written warning instead.
Utilities detect violations through drive-by patrols, neighbor complaints, and smart meter data that shows water use on non-permitted days. After multiple violations, some providers install flow-restriction devices on the meter, which physically limits how much water reaches the property.
If You’re on a Private Well
Being on a private well doesn’t automatically free you from watering restrictions. In many areas, the regional water management district’s conservation orders apply to all water users within their boundaries, including well owners, because wells draw from the same aquifer that feeds the public supply. Check with your water management district rather than your city utility if you’re on a well.
When Your HOA Pushes Back
Homeowners’ associations sometimes create a conflict: the utility tells you to cut back on irrigation, and the HOA threatens fines for brown grass. Several states have passed laws prohibiting HOAs from penalizing homeowners for reduced landscaping during active water restrictions. The scope of these preemption laws varies, but the core idea is that a government conservation order overrides HOA aesthetic standards.
If you’re getting pressure during a declared drought, check whether your state has a preemption statute. Even without one, the practical argument is strong: complying with a government water restriction isn’t optional, and the HOA’s authority doesn’t extend to overriding local law.
Pool Filling and Topping Off
Pools get their own set of rules. At moderate conservation stages, many utilities distinguish between filling a new pool (usually prohibited without a permit) and topping off an existing pool to replace evaporation (often still allowed, sometimes only on specific days). At higher drought stages, even topping off may be restricted to certain hours or banned.
If you’re planning to build, drain, or refill a pool, check your utility’s current stage before scheduling the work. Filling a pool during a drought is one of the more visible violations, and fines for it tend to land at the higher end of the range.
