The success of recycled water customers is important to the overall success of Denver Water’s recycled water program. Denver Water continues to look for ways to help recycled water customers keep their landscapes healthy and vibrant. Since Denver Water started delivering recycled water in 2004, it has conducted five different studies detailing the effects of recycled water on soil, plants and trees.
Recently, Colorado State University, Day & Associates, and the team of PRZ Sports Turf Consulting and THK Associates completed studies evaluating soil and tree conditions and associated management options.
Results showed that soil and tree health 
depend on factors such as soil characteristics, climate, management practices and water quality. Researchers found that sites with elevated sodium levels may benefit from applying sulfur burners, sodium blockers or using low trajectory spray heads. The payback period could be as short as a few months to two years because of the significant discount in recycled water rates compared to potable water rates.
Using recycled water for irrigation is a great way to free up drinking water for other purposes. By implementing successful management practices, customers will have landscapes that flourish in Colorado’s dry climate.
