Backflow Prevention Letter

Brighton Utilities Department has sent the following letter regarding backflow prevention inspections to its customers:

In an effort to provide maximum protection of municipal water systems in the state, the Colorado Department of Public Health and Environment (CDPHE) has established a program that requires all industrial and commercial customers to test their backflow devices and submit results once a year. Backflow prevention devices are used  to ensure that impurities do not enter the treated drinking water supply. In order to meet state standards, the City of Brighton is required to receive test results from at least 70 percent of our  industrial and commercial customers and subsequently, document those results. 

During a routine review of reports from our 2018 backflow testing program, City staff identified duplicate businesses listed on the results. We then self reported this to CDPHE. As a result of the redundancy, we did not meet the state’s minimum standards of 70 percent of test results and in compliance with the state, we are notifying you of this.

On a daily basis, the City extensively tests the quality of water to ensure we are providing safe, drinkable water to our community. The testing has consistently verified the safety of Brighton’s water. There is no evidence that the public’s drinking water was at risk. Additionally, we are immediately implementing better practices for tracking customer compliance and test results. 

To prevent this from happening again,  City staff will be proposing and implementing program recommendations that will enhance and ensure future compliance. It is always the intent of the City to take necessary actions to keep our community safe.

If you have questions concerning this notice, please do not hesitate in contacting Bradley Dallam, Utilities Assistant Director, at 303-655-2033 or
