Landscape contractors should be aware of upcoming changes to the pH in drinking water delivered to Denver Water customers. ALCC is collecting questions and concerns from green industry professionals about the change. 

Currently, the pH of Denver Water ranges from 7.5 to 8.5, with a target of 7.8. During the first week of March, Denver Water will be increasing the pH range to be between 8.5 and 9.2, with a target of 8.8.  

The change is part of Denver Water’s Lead Reduction Program. Increasing the pH of drinking water will reduce its corrosivity and better protect customers with lead in their home plumbing and service lines. 

Denver Water recognizes that this may affect operations of green industry professionals who serve customers of Denver Water. Professionals are invited to share their thoughts and ask questions via a form (which can be anonymous) at www.alcc.com/pH20. ALCC will communicate with Denver Water to help all parties better understand any effects this change will have on landscape care.
