WATER TREATMENT

The Louisville Water Treatment Division handles all water treatment for the City through its two treatment plants. Water is provided for residents from South Boulder Creek and the Northern Colorado Water Conservation District.

January 17th Letter to Residents

The City of Louisville was required to send notice to water customers regarding a Backflow and Cross Connection Control Program Violation, which took place in 2016 through 2018. The violation was related to records of inspection.

As the letter mentions, no action is required from water customers. Your tap water meets or exceeds all regulatory requirements. In 2019, all of the Colorado Department of Public Health and Environment's requirements were met and the City was in compliance.

More information on the Cross Connection Control Program, established in 2005, is available on our website.

Your water in 2016-2018

In the 2016-2018 period, Louisville's drinking water was safe to drink. Read the 2018 Water Quality Report for more details. 

During the 2016-2018 period, the storage reservoirs and their sources were routinely monitored for contaminants that could create a health risk or interfere with the water treatment process.

The City of Louisville remains committed to providing clean, safe drinking water.

If you have any questions or concerns, please contact Cory Peterson by email or phone 303-335-4610.
