If your lawn is looking a little stressed this season, you’re not alone. Across Denver and the Front Range, water providers have implemented strict watering restrictions due to one of the driest winters on record. With snowpack levels at historic lows, 2026 has ushered in a new era of conservation—and homeowners need to be informed.
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

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, 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
At New Windows for America, we believe smarter homes start with smarter choices—inside and out. And in a year like this, every drop—and every degree—counts.
