Current Water Quality Report

Castle Pines North Metro District (CPNMD) is committed to providing high-quality, dependable drinking water and wastewater services to our community at the lowest possible cost. Making sure you get the water you need every day is what we do.

Our CPNMD current water quality report covers data from the 2024 calendar year. The report is produced each spring and provides essential information about your water supply—where it comes from, how it is treated and tested, and how we comply with the standards established by state and federal regulators. We work closely with the Colorado Department of Public Health and Environment (CDPHE) to monitor water quality and ensure compliance with all safety standards.

We have also included the water quality report by Highlands Ranch Water,  as they are our wholesale water system drinking water provider between October and April each year. 

Our Public Water System ID is CO011806.

If you have any questions about this report or would like to learn more about your water service, please contact Nathan Travis at 303-688-8550 or email us at info@cpnmd.org. We’re here to serve you!
