Rainwater Harvesting

Rainwater is a valuable renewable resource! It falls from the sky and provides our landscapes with life sustaining water. This resource can be passively harvested to yield the abundance for weeks or months after a rain.

28 United Watershed States of America

Colorado is at the top of America’s watersheds, sending our snowmelt into rivers that flow East to the Mississippi, and West to the Pacific Ocean via the Colorado River. A popular saying in the West is, ”Whisky is for drinking and water is for fighting” and for years this topic has been hotly debated throughout Colorado and the West. The first man to successfully navigate the Colorado River, said that we should divide our states by watershed, and not by arbitrary dividing lines, to avoid conflict and fights over these life sustaining waters.

It has traditionally been illegal to stop the flow of any source of water in the west, without expensive water rights. This has included everything from simple rain barrels to dams and lakes, without specific permits. However, what hasnt been discussed is that it has never been illegal to divert downspouts directly into the landscape, allowing that water to slow, sink, and spread into the ground. This style of Rainwater Harvesting is our passion here at Colorado Greywater. We thrive in the space of design and installation of simple earth shaping for passive water harvesting also called ‘Earthworks’. We can shape the earth to passively harvest water, while producing beautiful perennial landscapes and abundant food!

Do you have Flood Problems? Earthworks can function in both ways. During dry times, they serve as  a water harvesting solution. During wet times, they can effectively keep flood waters from getting to your home. We can work with flood specific solutions on mountain properties and in residential flood plains.

With the recent passage of the new Colorado RainBarrel Bill (HB 16-1005) residents now have the opportunity to catch and store rainwater for later use in their landscape. This is exciting news, as it offers a shift in the conversation for the first time in more than a hundred years. The Bill allows for 110 gallons of storage capacity for each residential property. See our Parts & Materials Page for ideas on how to build your own rainbarrel solution. Or Contact Us to see how we can help you design a water harvesting solution, including earthworks, rainbarrles, and perennial planting of your landscape.
