The Jasmine Project

Local Study Helps Greenwood Village Residents Conserve Water and Save Money on their Water Bills
Village resident Bob Doyle wanted to make a difference for his community. He initiated the Jasmine Project in 2013, a water-saving study to assess residential irrigation water use in his Greenwood Hills neighborhood. As a result of the study, 14 residents achieved an average annual savings of $700 on their water bill. The Jasmine Project was the inspiration for Greenwood Village and Denver Water to partner this spring and summer to educate residents about the success of water conservation.

“Thanks to resident Bob Doyle for his admirable work on this project, we now appreciate that just some simple fixes with our irrigation systems can have a profound impact on water use and those monthly water bills,” said Mayor Ron Rakowsky. “Our goal with educating citizens about this project is that all of our residents will work with Denver Water in the months ahead so that similar water savings measures can be implemented across our entire community.”

The Study

The Jasmine Project was a study to assess and apply best management practices and irrigation technology for saving residential irrigation water based on irrigated area and plant types for homeowners of Greenwood Hills. This Village neighborhood is characterized with large, mature residential properties, each an acre or larger, that require above average amounts of irrigation water to maintain healthy landscapes and property values. Irrigating these properties during the summer can cost each resident $300 to more than $1,000 per month.

In an effort to identify water savings opportunities, Denver Water completed free water audits for 14 homeowners located in Greenwood Hills. More than 100 recommendations were made by Denver Water to homeowners to achieve efficient outdoor watering, including leak repairs; irrigation nozzle retrofits; manual system shut-offs during and after rainstorms; installation of rain sensors to automatically prevent irrigation systems from running after rain; and replacement of turf with xeric plants that require less water.

“It’s great to have the opportunity to engage with residents about water conservation, and even better that Greenwood Village is willing to work with us to promote programs that help to save water,” said Brandi Honeycutt, Conservation Specialist, Denver Water. “We are excited about the partnership and the success during the months to come.”

Thirteen out of 14 homeowners reduced outdoor water use from the baseline year (2012) to the study year (2013) when water savings measures were implemented. The water saving efforts contributed to an adjusted average net reduction of more than 70,000 gallons per resident and an average annual savings of more than $700 per resident per year (range $162 - $1,372).

“I was pleasantly surprised that the results were astounding the way they came out,” said resident Bob Doyle. “We have a lot to learn about how we can save water. I think this is just the beginning of that process.”

Residents Call to Action &Ndash; Denver Water to Send Letters Starting in May

Beginning in May, all single family households in Greenwood Village will receive a letter each month until September. The letter will include a graph showing the target water consumption amount based on the property’s irrigated area, and will show the actual amount of water being used. This will allow customers to see whether they are using more water than their landscape needs so they can make adjustments to reduce water if they are using too much. Water saving tips will be provided in the letter and are also available at

To calculate the maximum irrigation requirement, Denver Water will use GIS to measure irrigable areas of your property. The irrigable area will be used to calculate a maximum efficient target and will be adjusted for weather. Indoor use throughout the year is based on winter use at the property.

In addition, the letter will compare residents to their neighbors with similar landscape characteristics. Village residents wanting to implement water savings techniques may sign up for a free water audit beginning on May 15. To sign up for an audit, contact Brandi Honeycutt of Denver Water at 303-628-6216.
