Glendale CO Water Restrictions 2026

Current water restrictions in Glendale, Colorado

Glendale is under Stage 1 Mandatory restrictions issued by Denver Water, limiting outdoor irrigation to 2 assigned days per week, effective March 25, 2026, through October 1, 2026.

Denver Water declared Stage 1 on March 25, 2026, in response to the South Platte Basin snowpack falling to 42% of normal — the worst measurement on record for that date. Because Glendale is a fully enclosed enclave city within the city and county of Denver, it has no independent water utility; Denver Water is the sole supplier and the authority enforcing these rules for every address inside Glendale's boundaries.

The drought context is severe statewide. Colorado's Front Range is operating under emergency drought conditions, with more than 20 municipalities under mandatory schedules. Erie is at Stage 2 Drought (downgraded from Level 4 in May), now allowing 2 days/week watering; Eagle River is at Stage 3. Glendale's Stage 1 is among the less restrictive tiers currently active in the region, but Denver Water has indicated it will escalate if the deficit worsens.

Practically, these restrictions affect nearly every outdoor water use in Glendale. The city's dense, urban character — high-rise apartments, commercial strips along Colorado Boulevard, and small landscaped common areas — means most residents are dealing with relatively compact outdoor spaces, but the rules apply equally to window boxes watered by hose, turf on multifamily properties, and commercial frontage irrigation systems. A resident with an even-numbered address cannot water their garden on a Wednesday morning; they must water before 10:00 a.m. or after 6:00 p.m. on Sunday or Thursday only. An odd-addressed resident would use Wednesday or Saturday, not Sunday.

Watering schedule and allowed days

Your watering day is determined by the last digit of your street address as recorded in Denver Water's billing system. If the last digit is 0, 2, 4, 6, or 8, you are an even-address customer and water on Sundays and Thursdays. Odd digits (1, 3, 5, 7, 9) mean Wednesdays and Saturdays. If you are unsure of your classification, Denver Water's customer portal at denverwater.org allows address lookup, or you can call 303-893-2444.

Multifamily buildings and HOA-managed common areas — including the landscaped strips and courtyard turf common in Glendale's apartment complexes — operate on a separate Tuesday/Friday schedule regardless of the building's street number. Property managers along Cherry Street and the Colorado Boulevard corridor should confirm their irrigation controllers are programmed to these days and not running on the residential calendar. Commercial properties along Colorado Boulevard are subject to the same schedule as their address parity unless their account is classified as a common-area account by Denver Water.

Certain trees that are well established in Glendale's urban canopy need priority during restricted watering windows. Honey locust (Gleditsia triacanthos), widely planted along Glendale's streetscapes, is drought-tolerant but benefits from deep, infrequent watering on your assigned days. Bur oak (Quercus macrocarpa), planted in several Glendale pocket parks, requires deep soil moisture especially through a dry spring. Austrian pine (Pinus nigra), a common Front Range ornamental, can suffer needle scorch under prolonged deficit; slow drip irrigation to the root zone on assigned days is permitted and recommended. Hand watering with a shutoff nozzle remains exempt and is the most efficient way to target established trees without burning a full irrigation cycle.

What happens if you violate restrictions in Glendale?

Denver Water enforces Stage 1 restrictions through a combination of advanced metering infrastructure (AMI), complaint-based reporting, and field patrols. Denver Water has deployed smart meters across most of its service area, including Glendale accounts, that record water use in 15-minute intervals. Automated analytics flag accounts that show irrigation-level consumption outside permitted hours or on non-assigned days, allowing the utility to identify likely violations without a neighbor report. Residents and property managers can also submit complaints through the Denver Water website or by calling 303-893-2444; the utility typically responds to complaint-triggered reviews within several business days.

If you receive a warning letter and believe the violation was caused by a controller malfunction, a guest, or a billing address discrepancy, Denver Water does have an informal review process. Contact their conservation team at the number above with documentation — a repair receipt, a meter anomaly explanation, or evidence of the controller issue. First-offense warnings are not automatically reversible, but second-offense fines ($250) can be contested before payment is required. Escalation to $500 fines occurs only when violations accumulate within a rolling 12-month window.

Other outdoor water rules

Stage 1 restrictions in Denver Water's service area extend beyond lawn irrigation. The following rules apply to all Glendale addresses:

• Car washing: Permitted only with a hose fitted with an automatic shutoff nozzle. Commercial car washes that recirculate water are unrestricted. Washing on a driveway that drains to a storm sewer without recapture is discouraged but not prohibited under Stage 1.
• Fountains and decorative water features: Must be equipped with a recirculating pump. Draining and refilling decorative fountains without recirculation is prohibited.
• Swimming pools and hot tubs: Initial filling is permitted; topping off to replace evaporation is allowed. Draining and refilling an existing pool without Denver Water approval is not permitted under Stage 1. Pool covers are strongly encouraged to reduce evaporation losses — particularly relevant for Glendale's residential and apartment complex pools.
• Pressure washing: Structures and hardscapes may be pressure washed only when necessary for health or safety, not routine cleaning. Use of a recirculating system or collecting runoff is expected.
• Construction water use: Contractors operating in Glendale must comply with Denver Water's construction account restrictions. Dust suppression and concrete curing uses are subject to Stage 1 conservation guidelines.
• Restaurants and commercial food service: Serving water only upon request is required under Stage 1. This applies to Glendale's restaurant corridor along Virginia Avenue and Colorado Boulevard.
• New sod installation: Strongly discouraged during Stage 1. If installed, a 30-day establishment watering variance must be registered with Denver Water in advance.

Water source and infrastructure

Glendale receives 100% of its treated drinking water from Denver Water, which operates one of the largest municipal water systems in the Rocky Mountain West. Because Glendale has no independent infrastructure, its supply is entirely dependent on Denver Water's storage, conveyance, and treatment network.

Denver Water's primary raw water sources are the South Platte River and the Blue River, both originating in the high-country watersheds of the Rocky Mountains. The Blue River feeds Dillon Reservoir in Summit County — Denver Water's largest single storage asset, with a capacity of approximately 257,000 acre-feet. Water from Dillon is conveyed beneath the Continental Divide through the Harold D. Roberts Tunnel, one of the longest water tunnels in the world, into the South Platte drainage.

Additional storage comes from Gross Reservoir on South Boulder Creek in Boulder County, which Denver Water is currently in the process of expanding under the Gross Reservoir Expansion Project, a project that will increase capacity to 119,000 acre-feet when complete. Cheesman Reservoir and Antero Reservoir provide further storage along the South Platte system.

Raw water from these mountain sources is treated at Denver Water's Marston Treatment Plant in southwest Denver and the Moffat Treatment Plant near Lakewood before entering the distribution system that supplies Glendale. The Marston plant draws from the South Platte; the Moffat plant processes water delivered through the Moffat Tunnel and Gross Reservoir system.

The current drought declaration is directly tied to the South Platte Basin snowpack registering at 42% of normal — the worst on record for the March 25 measurement date. With Dillon Reservoir inflow projections far below average, Denver Water moved to Stage 1 to protect storage levels through the 2026 irrigation season. Glendale residents are drawing from the same stressed reservoirs as all Denver Water customers across the metro area.

Brown lawn protections in Colorado

Colorado law provides direct protection for homeowners whose lawns turn brown during mandatory water restrictions. CRS § 37-60-126 prohibits homeowners associations from fining, penalizing, or threatening legal action against a property owner whose landscaping declines or goes dormant as a result of compliance with a government-mandated water restriction. Because Denver Water's Stage 1 restrictions are mandatory and issued by a public utility authority, Glendale homeowners and tenants in HOA-governed properties are covered by this statute for the duration of the Stage 1 restriction period through October 1, 2026.

If your HOA sends a violation notice related to brown turf, dead grass, or reduced irrigation during the current Stage 1 restriction period, you are not required to comply with any HOA demand that would require you to violate Denver Water's schedule. Document the HOA notice and your response in writing. You may also contact Denver Water at 303-893-2444 to request a letter confirming the mandatory nature of the current restrictions.

Use the following template as a starting point for your written response to an HOA:

"This notice is to inform [HOA Name] that any reduction in landscaping or turf condition at [your address] is the direct result of compliance with Denver Water's Stage 1 Mandatory water restrictions, declared March 25, 2026, and currently in effect through October 1, 2026. Under Colorado Revised Statutes § 37-60-126, a homeowners association may not impose fines or penalties on a property owner for landscape conditions caused by adherence to a government-mandated water restriction. I am in compliance with my assigned watering schedule and request that this matter be closed without penalty."

Lawn care during restrictions

Glendale sits at approximately 5,400 feet elevation in a semi-arid climate, and the cool-season grasses common to Front Range lawns respond differently to water stress than warm-season turf. Understanding your grass type helps you use both of your weekly watering days as efficiently as possible.

Kentucky Bluegrass dominates most of Glendale's residential and commercial turf, but it is the thirstiest option on this list. Under Stage 1 restrictions, many bluegrass lawns will enter partial dormancy — the grass browns on the surface but the crown and root system survive if given a deep soak on each of the two assigned days. Set irrigation controllers to run long enough to deliver 1 inch of water per session rather than two shallow waterings. At Glendale's elevation, evapotranspiration rates climb sharply through June and July, so timing both watering windows early morning (before 10:00 a.m.) maximizes soil uptake before afternoon heat. Mow bluegrass at 3 to 3.5 inches during drought stress — cutting shorter removes the shading that protects root zones from the intense sun at elevation.

If you have or are considering Buffalograss or Blue Grama — both native Front Range prairie grasses — Stage 1 restrictions present minimal stress. These grasses evolved for exactly these conditions and can sustain themselves on natural rainfall supplemented by one deep watering per week. Denver Water's Xeriscape Incentive Program offers rebates for replacing thirsty bluegrass turf with low-water native alternatives; converting even a portion of a Colorado Boulevard commercial frontage or apartment common area to native grass or xeric plantings reduces annual water demand substantially and positions properties for easier compliance if Denver Water escalates to Stage 2.

Common questions about Glendale water restrictions

What days can I water at my Glendale address?

It depends on whether your street address ends in an even or odd number. Even-numbered addresses (ending in 0, 2, 4, 6, or 8) may water on Sunday and Thursday. Odd-numbered addresses (ending in 1, 3, 5, 7, or 9) may water on Wednesday and Saturday. Multifamily buildings and HOA-managed common areas use Tuesday and Friday. All outdoor irrigation must occur before 10:00 a.m. or after 6:00 p.m. on those days. Confirm your assignment at denverwater.org or call 303-893-2444.

What is the fine for watering on the wrong day in Glendale?

Denver Water issues a written warning letter for the first confirmed off-schedule violation — no monetary penalty. A second violation within the same 12-month period carries a $250 fine. Any additional violations within 12 months escalate to $500 per occurrence. Fines are assessed to the Denver Water account associated with the address, which may mean the building owner rather than a renter receives the notice.

Does Denver Water use smart meters to catch violations in Glendale?

Yes. Denver Water has deployed advanced metering infrastructure (AMI) — smart meters that record water flow in 15-minute intervals — across its service territory, including Glendale accounts. The utility's data analytics system flags consumption patterns consistent with irrigation running outside permitted hours or on non-assigned days. You do not need a neighbor to report you; automated meter analysis can identify likely violations independently. That said, neighbor and passerby reports submitted through denverwater.org also trigger reviews.

Can I wash my car at home in Glendale during Stage 1?

Yes, but only with a hose equipped with an automatic shutoff nozzle. Letting a hose run freely while washing a car is prohibited under Stage 1 rules. Commercial car washes that use water recirculation systems are not subject to the same restriction and may operate normally. If you wash your car on a non-watering day, the shutoff nozzle requirement still applies — hand washing with a bucket and shutoff hose is the safest approach.

What rebates does Denver Water offer for replacing turf in Glendale?

Denver Water's Xeriscape Incentive Program (ZIP) pays qualifying customers $1.50 per square foot of irrigated turf removed and replaced with low-water landscaping. Commercial properties along Colorado Boulevard with large irrigated frontage may be eligible for significant rebates. Applications must be submitted and approved before removal begins. Visit denverwater.org or call 303-893-2444 to start the application. Denver Water also offers free Xeriscape design consultations for both residential and commercial customers.

My apartment building is in Glendale — does my landlord have to follow these rules?

Yes. Denver Water's Stage 1 restrictions apply to the water account serving the building, which is typically held by the property owner or management company. Multifamily common-area irrigation — including shared courtyards, parking lot landscaping, and poolside turf — must run on the Tuesday/Friday schedule before 10:00 a.m. or after 6:00 p.m. If you observe your building's irrigation system running at prohibited times or on wrong days, you can report it to Denver Water at 303-893-2444 or through their online complaint form. Fines issued to the building account are the landlord's financial responsibility, not the tenant's.

Is drip irrigation exempt from the 2-day schedule in Glendale?

Yes. Drip irrigation systems are fully exempt from both the day restrictions and the hour restrictions under Denver Water's Stage 1 rules. You may run a properly installed drip system on any day at any hour. This exemption applies to garden beds, tree watering rings, and container drip setups — as long as the system delivers water directly to the root zone and does not involve spray heads or rotors. If your system uses a combination of spray and drip zones on the same controller, the spray zones must comply with the 2-day schedule even if the drip zones are exempt.

When are Stage 1 restrictions expected to end in Glendale?

Denver Water's current Stage 1 declaration runs through October 1, 2026, but the end date is tied to reservoir storage and hydrological conditions, not just the calendar. If the South Platte Basin recovers storage at Dillon Reservoir or Gross Reservoir ahead of schedule, Denver Water could lift restrictions earlier. Conversely, if storage continues to decline through summer, the utility could escalate to Stage 2 — which would reduce allowed watering days further and add additional use restrictions. Denver Water announces changes at denverwater.org and through customer email alerts. Sign up
