Understanding your city’s specific watering rules is essential to avoid fines, protect your landscaping, and do your part in preserving Colorado’s water supply.

Why Water Restrictions Are Happening in 2026

Denver and much of the Front Range rely heavily on mountain snowpack for water—up to 90% of supply. This year’s unusually warm and dry winter has forced municipalities into Stage 1 drought restrictions, with a shared goal of reducing water use by around 20%. 

The biggest impact? Outdoor watering.

Denver Water Restrictions (including Lakewood, Littleton, Centennial)

For homes served by Denver Water:

Lawn Watering:

• 2 days per week maximum
• Even addresses: Sunday & Thursday
• Odd addresses: Wednesday & Saturday
• Commercial: Tuesday & Friday

Time Restrictions:

• Only before 10 a.m. or after 6 p.m.

Additional Rules:

• No watering during rain or wind
• Prevent runoff into streets
• Repair leaks within 10 days
• Use shut-off nozzles for hoses

These restrictions are mandatory and expected to remain in place through the irrigation season. 

Water Restrictions Across the Front Range

While many cities mirror Denver, others have their own specific guidelines:

Brighton (Stage 1 – Mandatory)

Brighton has implemented some of the strictest enforcement measures:

• Watering limited to 2 days per week
• Even addresses: Tuesday & Friday
• Odd addresses: Wednesday & Saturday
• No irrigation between 10 a.m. – 6 p.m.
• Sod installation restricted (over 200 sq ft prohibited)
• No water waste (runoff, pooling, etc.)

Hand watering is still allowed for plants and trees. 

Broomfield (Drought Watch / Stage 1 Alignment)

Broomfield is currently under a drought watch with structured conservation rules:

• Typically up to 3 days per week, but reduced to 2 days during drought conditions
• Even addresses: Sunday & Thursday
• Odd addresses: Wednesday & Saturday
• Water only between 6 p.m. – 10 a.m.
• No runoff or water waste
• Leak repairs required within 10 days

Residents are strongly encouraged to reduce usage voluntarily. 

Golden (Jefferson County / Denver Water Service Areas)

Golden largely follows Denver Water guidelines:

• 2 days per week watering
• Assigned watering days based on address
• No watering between 10 a.m. – 6 p.m.
• Focus on reducing total water use by 20%

Because many Golden residents are served by Denver Water or similar providers, restrictions align closely with metro-wide rules. 

Lafayette

Lafayette is currently operating under Stage 1 Drought Response and year-round water conservation ordinances.

• 2 days per week watering

Smart Ways to Reduce Outdoor Water Use

Even with restrictions, you can maintain a beautiful yard—just more efficiently.

Water Early or Late

Avoid evaporation by watering during cooler hours (before 10 a.m. or after 6 p.m.).

Upgrade Your Irrigation

Smart sprinkler systems and drip irrigation can reduce water waste dramatically.

Xeriscape Your Yard

Replace high-water grass with drought-tolerant plants designed for Colorado’s climate.

Mulch & Maintain Soil

Mulch helps retain moisture and reduces watering frequency.

Fix Leaks Fast

Even small leaks can waste thousands of gallons over time.

The Bigger Picture: Energy Efficiency Starts at Home

While outdoor watering is the focus of restrictions, many homeowners overlook how their home itself impacts energy and environmental efficiency.

Older, inefficient windows can:

• Increase indoor temperatures
• Force HVAC systems to work harder
• Contribute to higher overall resource consumption

Upgrading to energy-efficient windows helps regulate indoor temperatures naturally—reducing strain on your home and supporting a more sustainable lifestyle. It’s not just about comfort—it’s about being smarter with every resource your home uses.

Final Thoughts

Water restrictions across Denver, Brighton, Highlands Ranch, Arvada, Broomfield, Golden, and the greater Front Range are a necessary response to serious drought conditions. But they’re also a reminder: small changes can make a big difference.

By adjusting your outdoor watering habits and improving your home’s efficiency, you can:

• Stay compliant with local regulations
• Protect your landscaping
• Lower utility costs
• Contribute to Colorado’s long-term sustainability
