Aurora CO Water Restrictions 2026

Current water restrictions in Aurora, Colorado

Aurora is under Stage 1 Drought restrictions, limiting outdoor watering to 2 assigned days per week, effective April 11, 2026. Aurora Water declared the Stage 1 drought that day, targeting a 20% reduction in overall water usage across residential, multi-family, and commercial customers. The declaration also imposed an immediate ban on all new turf lawn installations throughout the city.

The restrictions are mandatory, not voluntary, meaning customers are expected to comply regardless of how green their lawn looks or what the weather has been. Aurora Water manages the city's water supply and is the enforcing authority — you can reach them at auroragov.org/water.

Aurora's Stage 1 declaration fits into a broader Front Range emergency. Denver Water entered Stage 1 on March 25, 2026, Erie escalated to Level 4 with all irrigation prohibited, and over 20 Front Range municipalities are currently under mandatory schedules. Colorado's statewide drought status is severe enough that water managers across the region are actively coordinating reductions.

Practically speaking: a resident cannot freely water their garden on a Wednesday morning — or any morning — unless Wednesday falls on one of their two assigned watering days. Even on an assigned day, watering between 10 a.m. and 6 p.m. is prohibited. That means early morning or evening watering on your designated days only. The ban on new turf installation means you cannot lay sod or seed a new lawn anywhere on your property right now without potentially triggering enforcement. Stage 1 restrictions remain in effect until conditions improve — there is no fixed end date.

Watering schedule and allowed days

Aurora Water assigns your two weekly watering days based on your property address — typically keyed to whether your address ends in an odd or even number, or by street segment. If you are unsure which days apply to your address, contact Aurora Water directly through auroragov.org/water to confirm your specific assignment. Do not assume your days match a neighbor on a different street.

Multi-family and commercial properties follow the same two-day-per-week limit, though irrigation system complexity at larger properties may require coordination with Aurora Water's commercial customer team. HOAs that manage shared irrigation systems for common areas are also subject to the two-day limit and must update their controllers accordingly — running a shared system on a third day exposes the HOA to surcharges, not the individual residents.

Trees are a priority concern during Stage 1 restrictions in Aurora. Drip irrigation to established trees is exempt from the day and hour restrictions, which matters for large-canopy species common across the city. Bur oak (Quercus macrocarpa), Colorado blue spruce (Picea pungens), and honeylocust (Gleditsia triacanthos) are widely planted across Aurora's residential neighborhoods and urban tree canopy. All three can sustain significant root damage in drought conditions if deep watering is skipped for more than two to three weeks — using drip irrigation or a soaker hose placed at the dripline during your off-days is both legal and strongly advisable.

What happens if you violate restrictions in Aurora?

Aurora Water's enforcement model during Stage 1 is primarily surcharge-based rather than flat-fee citation-based. Rather than issuing a fixed dollar fine per incident, Aurora applies drought surcharges to your water bill when your consumption crosses defined usage tiers. The more you exceed your allocation, the higher the surcharge rate on that excess water. This means a household that consistently over-waters will see escalating costs each billing cycle, not a one-time penalty. Aurora Water's smart meter infrastructure — the city has been expanding Advanced Metering Infrastructure (AMI) coverage — allows staff to identify usage spikes without a physical site visit. Complaints from neighbors or drive-by patrol observations by Aurora Water field staff can also trigger account reviews.

If you believe a surcharge was applied in error — for example, you had a leak, or your tenant watered without authorization — Aurora Water does have a formal dispute and review process. Document the issue (repair receipts, plumber invoices) and contact the utility directly. Responses to reported violations and billing disputes typically occur within one to two billing cycles, though urgent complaints about active misuse may be triaged faster.

Other outdoor water rules

Beyond lawn irrigation, Stage 1 in Aurora restricts or governs several other outdoor water uses. The new turf installation ban is among the strictest measures in this phase — it applies citywide regardless of project size.

• New turf lawn installation: Completely prohibited under Stage 1. Sod, seed, or hydroseed for new lawn areas may not be installed.
• Car washing: Permitted only with a shut-off nozzle on the hose, or at a commercial car wash that recycles water. Letting a hose run freely is not allowed.
• Ornamental fountains and water features: Must be turned off or recirculating only. One-pass water features that discharge to drain are prohibited.
• Pool and hot tub filling: Filling or topping off pools is restricted — use a cover to reduce evaporation losses and minimize refill needs. Initial fills for newly constructed pools may require a variance from Aurora Water.
• Pressure washing: Non-essential pressure washing of driveways, patios, and sidewalks is discouraged and may violate the spirit of the Stage 1 order depending on water volume used.
• Construction water use: Dust suppression and construction site irrigation must use the minimum volume necessary; Aurora Water may require documentation for large commercial sites.
• Restaurant table water: Not a Stage 1 trigger in Aurora, but commercial customers face the same tiered surcharge structure as residential.

Water source and infrastructure

Aurora's water supply comes from a geographically diverse portfolio managed by Aurora Water, drawing on both mountain surface water and infrastructure shared with other Front Range utilities. The primary sources are the South Platte River system and transmountain diversions from the Colorado River basin via the Roberts Tunnel, which moves water from Dillon Reservoir on the Blue River under the Continental Divide to the Front Range.

Aurora holds direct water rights in the Homestake Reservoir system in Eagle County, jointly operated with Colorado Springs through the Homestake Partners agreement. Water from Homestake flows into the Arkansas River drainage, and Aurora exchanges those rights for South Platte deliveries. Aurora also holds rights in Spinney Mountain Reservoir and Antero Reservoir in South Park (Park County), both on the South Platte headwaters. These reservoirs feed Aurora's system through exchange and direct delivery arrangements.

On the treatment side, Aurora operates the Prairie Waters Project, one of the most sophisticated indirect potable reuse systems in the United States. Prairie Waters captures treated wastewater effluent discharged into the South Platte downstream, naturally filters it through riverbank infiltration galleries along a 38-mile pipeline corridor, and returns it to Aurora's water supply through the Peter D. Binney Water Purification Facility in Aurora. This facility has a treatment capacity of approximately 50 million gallons per day and significantly extends Aurora's supply resilience during drought.

Despite this infrastructure, the current Stage 1 declaration reflects the reality that snowpack in the Upper South Platte and Colorado River headwaters was below normal entering the 2026 irrigation season, reducing projected reservoir yields and pressuring the entire Front Range water grid simultaneously.

Brown lawn protections in Colorado

Colorado law protects Aurora homeowners from HOA enforcement actions related to brown or dormant lawns during mandatory watering restrictions. Colorado Revised Statutes § 37-60-126 prohibits homeowners associations from fining or penalizing a property owner for failing to irrigate landscaping when doing so would violate a water restriction order issued by the applicable water provider. Because Aurora Water's Stage 1 restrictions are mandatory, your HOA cannot legally penalize you for a dry or dormant lawn that results from following the two-day watering schedule.

If your HOA sends a violation notice related to lawn appearance during Stage 1, you have a legal basis to dispute it. Keep a copy of Aurora Water's Stage 1 declaration (available at auroragov.org/water) and reference the statute directly in your response.

Template response to HOA:

"Dear [HOA Board / Management Company], I am writing to dispute the violation notice dated [date] regarding lawn condition at [your address]. Aurora Water declared a mandatory Stage 1 Drought restriction on April 11, 2026, limiting outdoor irrigation to two assigned days per week. My current lawn appearance is a direct result of compliance with this mandatory restriction. Under Colorado Revised Statutes § 37-60-126, a homeowners association may not impose fines or penalties on a homeowner for failing to irrigate landscaping in violation of a water restriction order issued by Aurora Water. I respectfully request that this notice be rescinded. I am happy to provide documentation of Aurora Water's current Stage 1 declaration upon request."

Lawn care during restrictions

Aurora sits at roughly 5,400 feet elevation on the High Plains, which shapes both which grasses survive here and how they respond to stress. The two-day watering schedule requires strategic management to keep turf alive — or to allow it to go dormant safely rather than die.

Kentucky Bluegrass dominates Aurora's residential lawns but is the most water-demanding of the local options. During Stage 1, raising your mow height to 3–3.5 inches significantly reduces soil moisture loss — shorter cuts increase evaporation and stress the root system faster. Aurora's semi-arid climate at elevation means afternoon temperatures can spike well above 90°F in summer while humidity remains low, accelerating moisture loss. Water deeply on your two assigned days rather than lightly every permitted opportunity — deep watering encourages roots to extend downward rather than staying at the surface where they dry out fastest.

If your lawn goes fully dormant, resist the urge to overwater to green it back up prematurely. Dormant Kentucky Bluegrass can survive several weeks with minimal water — roughly half an inch per week is sufficient to keep the crown alive without actively growing the plant. Buffalograss and Blue Grama are well-suited to Aurora's climate and the city's ban on new turf installation does not prohibit converting existing irrigated lawn to these lower-demand native alternatives using plugs or overseeding into thin areas — a project worth planning for fall 2026.

Common questions about Aurora water restrictions

What are my two assigned watering days under Aurora's Stage 1 restrictions?

Your specific assigned days depend on your street address and are determined by Aurora Water's scheduling system. Most residential assignments are based on whether the property address is odd or even, but street segment variations exist across the city. Log in to your Aurora Water account at auroragov.org/water or contact Aurora Water directly to confirm which two days apply to your address. Do not water on days not assigned to you — even if a neighbor on your block appears to be doing so.

When exactly can I water on my assigned days?

On your two assigned days, you may water before 10 a.m. or after 6 p.m. Watering between 10 a.m. and 6 p.m. is prohibited during Stage 1, as midday irrigation loses a significant portion of water to evaporation before it reaches plant roots. Early morning — between 4 a.m. and 9 a.m. — is the most efficient window given Aurora's dry afternoon winds.

Can I water my garden vegetables every day, or does Stage 1 apply to vegetable gardens too?

Drip irrigation and soaker hose systems are exempt from the two-day schedule, meaning you can run a drip system in your vegetable garden any day and any hour. Hand watering with a shut-off nozzle is also exempt from day restrictions. If you are using a sprinkler or overhead system for a vegetable garden, the two-day limit applies. Switching your garden beds to drip or soaker lines is both legal under Stage 1 and more water-efficient for vegetables anyway.

Does Aurora Water use smart meters to catch violations?

Yes. Aurora Water has been rolling out Advanced Metering Infrastructure (AMI) smart meters across the service area. These meters transmit usage data at intervals short enough for Aurora Water staff to identify patterns consistent with watering on non-assigned days or during prohibited midday hours. Violations can be flagged without a physical inspection. Neighbor complaints submitted through the city's online portal can also trigger an account review, and Aurora Water field staff conduct periodic patrols during peak irrigation season.

My HOA is telling me to water more than two days a week or face a fine. What do I do?

Follow Aurora Water's mandatory Stage 1 restrictions, not your HOA's landscaping standards. Colorado Revised Statutes § 37-60-126 explicitly prohibits an HOA from penalizing you for lawn condition that results from compliance with a mandatory water restriction order. Aurora Water's Stage 1 declaration is a mandatory order. Send your HOA a written notice citing CRS § 37-60-126 and the Aurora Water Stage 1 declaration dated April 11, 2026. If the HOA proceeds with fines despite the statute, you can contact the Colorado HOA Information and Resource Center or consult a property attorney.

Can I install new grass or reseed my lawn right now?

No. Aurora Water's Stage 1 declaration includes a complete ban on new turf lawn installations. This covers sod, seed, and hydroseed for any new lawn area, regardless of size or location on the property. The ban is in effect citywide until Stage 1 restrictions are lifted. If you had an existing new sod installation already underway before April 11, 2026, contact Aurora Water about whether a 30-day establishment watering variance applies to your situation.

Does Aurora Water offer rebates for removing turf and installing drought-tolerant landscaping?

Aurora Water has historically offered rebates through its Xeriscape Incentive Program (XIP), which pays customers per square foot of irrigated turf converted to water-smart landscaping using approved plants, mulch, and efficient irrigation. Given the Stage 1 declaration and the new-turf ban, this program is particularly relevant right now. Check the current rebate rates and eligible plant lists at auroragov.org/water, as rebate amounts and funding availability can change during active drought periods.

How does Aurora's Stage 1 compare to what other Front Range cities are doing right now?

Aurora's Stage 1 is relatively moderate compared to several neighboring communities. As of spring 2026, Erie has reached Level 4 Emergency status with all irrigation prohibited, the most severe restriction possible. Eagle River is at Stage 3. Denver Water entered Stage 1 on March 25, about two weeks before Aurora's declaration. More than 20 Front Range cities are under mandatory schedules simultaneously, which means the regional water grid is under broad stress — Aurora's 20% reduction target is part of a coordinated effort across the South Platte basin to stretch available supplies through the summer irrigation season.

What days can I water my lawn in Aurora?

2 assigned days/week Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What time can I water in Aurora?

Watering is allowed Not 10am-6pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Aurora?
