WaterOne is committed to providing the community with high-quality, safe, and great-tasting tap water. To help empower the community with knowledge about their drinking water, information about WaterOne’s water is published annually in a Water Quality Report.
WaterOne’s Water Quality Report offers customers a better understanding of the water they are drinking. Also known as a Consumer Confidence Report (CCR), this publication uses plain language to explain technical findings, making complex water quality topics accessible to all members of the community. It includes details on WaterOne’s water sources, treatment processes, volume of water produced, safety and quality benchmarks, and much more.
The 2025 Water Quality Report provides data from WaterOne’s accredited laboratory about the composition of its water in 2024. In 2024, WaterOne conducted over 13,000 tests on more than 14,000 water samples to ensure that the water meets or surpasses all water quality standards.
Paper copies of the report are available at most Johnson County Library locations and at the WaterOne Administrative Office, located at 10747 Renner Boulevard in Lenexa.
