Project Description



Lower Bills, Reduce Waste Water, and Mitigate Flooding

Our Certified Passive Rainwater Harvesting Practitioners are here to help you lower your irrigation bills, reduce water waste, and mitigate flooding! Our passive rainwater collection techniques are integrated into your landscape so they do the work for you!

In March 2019 Columbine sent their President and Certified Designer Eva Montane, and Field Manager Colleen Hefferan to Tucson, AZ to participate in a Water Harvesting Certification Course offered by the Watershed Management Group.

In this course the two learned how to calculate a site’s water budget and match water-harvesting systems with appropriate landscaping. They studied and practiced active water harvesting which entails the storage of water in barrels and tanks, and passive water harvesting in the form of creating earthworks features – such as swales, berms, and infiltration basins. The duo learned to design, size, and install the appropriate technology to address the need of the site. Some common applications are low-maintenance ornamental landscaping, soil improvements, and supporting small-scale food production.

The work done by the Columbine team directs rainwater to the land where it’s slowed, pooled and soaked in deeply to hydrate the land. The rainwater is coming from impermeable surfaces such as roofs, driveways, and patios, as well as the rain that falls onto the landscape itself. Without rainwater harvesting this water would be diverted to the roads and sewer systems, bypassing the landscapes, and putting unnecessary burden on infrastructure. The landscapes would have continued to be dependent on treated water, pumped, piped and paid for.
