Rainwater Harvesting

Get information on rainwater collection, including learning about Denver’s laws on collection, building and utilizing rain barrels, and how to make the most of your harvest.

Rainwater Harvesting

Denver summers are getting hotter and longer. We need shade trees and cooling greenery around our homes. Rainwater -- a free resource! -- can help us save on water bills while also directing water to grow healthier shade trees and flowering perennials. Each year some 10,000 gallons of rainwater, snow, and dew collects on our roofs, only to go down storm drains. How do we harvest this valuable rainwater??

Our west Denver Rainwater Harvesting project is working with community leaders to provide residents with information and tools to:

  1. Lower their water bills while still keeping their garden growing, and
  2. Collect FREE rainwater to irrigate their trees and perennials. 

Added bonuses include conserving drinking water for all of Denver, and reducing pollution that runs into our streams from stormwater runoff.

The goal? Greener, cooler neighborhoods!

Events and Workshops

 

FREE Workshops and Materials for Barnum, Barnum West, Villa Park & Valverde! Paid for by Denver's Office of Climate Action Sustainability & Resilience, to help communities that have historically received fewer resources become more climate resilient. So let's take advantage! :)

Join us for a 3-part workshop series to find out how you can harvest your home's rainwater to grow more flowers and to water your trees. You'll end up with a design plan for your home, that meets your home's needs. And then you'll schedule a time this summer, when we'll help you install your rainwater harvesting design. 

You are welcome to sign up for one, two, or all three workshops. We look forward to learning with you. 

Hot breakfast, coffee, and hot chocolate included. 

Apply for FREE Materials!

FREE rainwater harvesting materials are available to community members in:

  • Valverde
  • Barnum
  • Barnum West
  • Villa Park

Rain barrels and downspout redirect materials will be available for pick-up in May, June and July, 2024. Mini rain garden kits with colorful perennials will be available in September. "How to" workshops and installation guides are available to all community members. Free installation help will be available to community members who need it.

UPDATE 7/17/24: Due to high demand, we have reached our goal of providing free solutions to 100+ West Denver households. We will now shift to assessing our outreach and campaign results, and then hope to be able to offer more rainwater harvesting solutions again in the future. Stay tuned for more info in coming months.

Yes, rain barrels are legal in Colorado!

In 2016, the Colorado legislature amended laws to make it legal for residents to collect and store up to 110 gallons of rainwater on their property. That would be two 55-gallon rainbarrel per plot.
