Rain barrels spark curiosity. They save water, cut bills, and help the planet. In Colorado, free rain barrels are available through workshops and programs. This guide covers everything about free rain barrels in Colorado. It answers your questions and shows you how to start. Expect practical tips, local resources, and clear steps. Let’s dive into rainwater harvesting and why it matters.
What Is a Rain Barrel and Why Use One?
A rain barrel collects rainwater from your roof. It’s usually a 55-gallon barrel with a sealable lid. You connect it to your downspout with a diverter installation kit. This setup captures stormwater runoff for outdoor purposes. Think watering gardens or washing cars. Rain barrels reduce water bills and ease pressure on storm drains. They also fight stormwater pollution by keeping runoff clean. In Colorado, water conservation is key due to limited water resources.
Rain barrels are simple but powerful. They support the hydrologic cycle and watershed protection. Using one shows environmental awareness. Plus, it’s a step toward combating climate change. Colorado’s dry climate makes every drop count. Free rain barrels make this solution accessible.
Why Colorado Encourages Rain Barrels
Colorado’s water laws are strict. House Bill 16-1005 changed the game. It legalized rainwater collection for residential use. Before, collecting rain was tricky due to water rights. Now, homeowners can use rain barrels legally. The Colorado Water Conservation Board supports this shift. It promotes water-saving practices like rainwater harvesting.
The state faces water scarcity. Urban waterways like the South Platte River need protection. Stormwater runoff carries pollutants into rivers. Rain barrels reduce this runoff. They also lower the risk of flooding. Programs like the Colorado Stormwater Center push for stormwater runoff reduction. Free rain barrel initiatives align with these goals.
How to Get Free Rain Barrels in Colorado

Free rain barrels are available across Colorado. Local programs and workshops make it easy. Here’s how to find them:
1. Attend Rain Barrel Workshops
Workshops teach you to build and install rain barrels. Groundwork Denver hosts Project Rain Barrel events. They offer free 55-gallon barrels and installation kits. You learn to set up a diverter and sealable lid. Workshops also cover mosquito breeding prevention with tools like Mosquito Dunks. Check schedules at places like Longmont Senior Center or Louisville Recreation and Senior Center.
2. Join Community Programs
Groups like Resource Central and Arapahoe County Environmental Program distribute free barrels. They often partner with the Coca-Cola Foundation. These programs focus on community engagement. Some require a small registration fee. Others, like Water Volunteers, provide barrels at no cost. Look for events at Lafayette Public Library or E-470 Administrative Building.
3. Apply for Permits
Colorado requires a Rooftop Precipitation Collection System Permit. The Division of Water Resources oversees this. The application process is simple. It ensures compliance with Colorado statutes. Check the Designated Basin Rules if you’re in a specific water basin. Exempt wells may not need permits, but always confirm.
4. Explore Local Resources
The Water Protectors Map lists rain barrel programs. Websites like Rain Barrel Resources offer guides. You can also find installation steps online. Some groups provide recycled barrels or upcycled rain barrels. These are eco-friendly and often free.
Benefits of Rain Barrels
Rain barrels do more than save water. They offer multiple perks:
- Lower Water Bills: Use collected rainwater for outdoor tasks. This cuts your water bills.
- Reduce Stormwater Pollution: Less runoff means cleaner storm drains and rivers.
- Prevent Mosquito Breeding: Sealable lids and Mosquito Dunks keep bugs away.
- Support Rain Gardens: Use rainwater to nurture rain gardens. These soak up runoff.
- Eco-Friendly Choice: Rain barrels promote water conservation and sustainability.
Step-by-Step Rain Barrel Installation
Setting up a rain barrel is straightforward. Follow these steps:
- Choose a Location: Place the barrel near a downspout. Ensure a flat, stable surface.
- Install the Diverter Kit: Connect the diverter to your downspout. It directs water into the barrel.
- Secure the Barrel: Use a 55-gallon barrel with a sealable lid. Elevate it slightly for easy access.
- Add Mosquito Protection: Place Mosquito Dunks inside to prevent breeding.
- Test the System: Run water through the downspout. Check for leaks.
For detailed guidance, check an installation guide from Resource Central. Many workshops include hands-on training.
Rain Barrel Maintenance Tips
Keep your rain barrel working well. Follow these tips:
- Clean Regularly: Remove debris from the lid. Flush the barrel yearly.
- Check for Leaks: Inspect the diverter and connectors. Fix any issues.
- Winterize the Barrel: Empty it before freezing weather. Store indoors if possible.
- Use Mosquito Dunks: Replace them monthly to stop mosquito breeding.
- Monitor Water Quality: Ensure the water stays clean for outdoor use.
Colorado-Specific Rain Barrel Programs
Several organizations lead the charge in Colorado. Here are key players:
- Groundwork Denver: Runs Project Rain Barrel. Offers free barrels and workshops.

Rain Barrels and Environmental Impact
Rain barrels tie into bigger environmental goals. They reduce stormwater runoff, which harms urban waterways like Bear Creek. They also support watershed plans. By collecting rain, you prevent water pollution. This keeps rivers like the South Platte River cleaner.
Rain barrels also fight climate change. They reduce demand on municipal water systems. This saves energy used in wastewater treatment facilities. Plus, they promote a Water Footprint Calculator mindset. You’ll use water more wisely.
Rain Gardens and Rain Barrels: A Perfect Pair
Rain gardens complement rain barrels. They’re shallow basins filled with plants. These soak up runoff from your yard. Use rain barrel water to irrigate them. This boosts stormwater runoff reduction. Boulder County promotes rain gardens for watershed protection. Combine them with barrels for maximum impact.
Legal Considerations for Rain Barrels in Colorado
Colorado’s laws are clear. House Bill 16-1005 allows two rain barrels per household. Each can hold up to 110 gallons. You need a Rooftop Precipitation Collection System Permit. The Graywater Control Regulation may apply if you use rainwater indoors. Always check with the Division of Water Resources.
Common Challenges and Solutions
Rain barrels aren’t perfect. Here are common issues and fixes:
- Mosquito Breeding: Use Mosquito Dunks. Keep the lid sealed.
- Overflow: Install a connector kit to redirect excess water.
- Leaks: Check the diverter and barrel seals. Tighten or replace parts.
- Permit Confusion: Contact the Division of Water Resources for clarity.
- Winter Freezing: Drain and store the barrel indoors.
