Water Quality

Our primary goal is to consistently provide our residents with safe and dependable drinking water. Sixty employees staffed 24 hours a day 365 days a year make sure that water is properly treated, adequately tested and efficiently distributed to homes and businesses. 

Arvada Water Quality Highlights

We adhere to stringent state regulations as required by law.
The City of Arvada continuously complies with the strict federal regulations of the Safe Drinking Water Act as well as state regulations provided in the Colorado Department of Public Health and Environment’s Primary Drinking Water Regulations. These regulatory limits have been established by the state and federal health departments to ensure public health and safety.

We consistently maintain the highest standards of water quality.
The City of Arvada water supply has never exceeded any of the regulatory limits and has never received a drinking water violation. The primary goal of the City of Arvada’s Water Treatment Division is to ensure the safety and health of our residents by producing and supplying the highest quality drinking water.

We provide an annual Water Quality Report.
The City of Arvada provides all customers with an annual Water Quality Report.  The purpose of the report is to share information and inform our customers about the high quality of their drinking water. We want you to know where your water comes from, what it contains and how it compares to stringent federal water quality standards. The City of Arvada's drinking water has met or exceeded the standards regulated by the State of Colorado and the U.S. Environmental Protection Agency.
