Did you know, the water that flows through your tap first flowed under the Rocky Mountain National Park? The Town’s drinking water primarily comes from the Colorado River that is delivered to Carter Lake. Learn more about where your water comes from, how it gets to your house and our plans to meet future water needs.
Annual Drinking Water Quality Report
The U.S. Environmental Protection Agency (EPA) requires that all community water systems provide their customers with an annual water quality report or Consumer Confidence Report. This requirement is part of the National Primary Drinking Water Regulations, as amended.
The Town of Frederick does not operate its own treatment plant; however, we do purchase treated water from Carter Lake. Under these arrangements, they are the agency that would compile and report the data that EPA requires.
View the annual report for the Town of Frederick. This information is supplied to you to comply with EPA regulation and give information that may be of interest to you about your drinking water. If you have specific questions about the information contained in the report, you should contact Carter Lake at 970-352-3624. If you have general questions about the EPA requirements, you should contact the EPA Safe Drinking Water Hotline at 1-800-426-4791.
IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER - Failure to Test Backflow Prevention Devices
Letter dated: February 8, 2022

Is my water safe to drink?
Your drinking water has been, and continues to be safe for consumption!
Why am I receiving a letter about my drinking water?
The State of Colorado drinking water program requires that all public drinking water systems test a percentage of backflow devices annually. The Town works with Aqua Backflow to ensure we are testing commercial backflow devices within the Town's drinking water system. The State collects paperwork with these results during a Sanitary Survey that was conducted on April 2, 2021. Unfortunately, the Town was not able to supply all the testing paperwork on the backflow devices from 2020 in the required timeframe. Therefore, a violation was issued, triggering the original letter to water customers. The Town had a deadline of August 28, 2021, to locate and submit the paperwork to prove backflow devices were tested and passed in the Town of Frederick. The Town did not meet the August deadline but worked with the State of Colorado to continue gathering the proper paperwork. State records show this as being resolved on October 6, 2021. As a result of missing the August 2021 deadline to turn in all paperwork and failing to notify residents of the violation in a timely manner, the Town is required to issue a second letter to water customers, which is the letter sent out in February 2022.
What did we do? The Public Works team located the missing testing information for 2020, which showed that the backflow devices thought to be un-tested in 2020 were in fact tested and passed. All paperwork was submitted to the State of Colorado. The State records show this as being resolved on October 6, 2021.
What should you do? No action is required, as the Town is in full compliance as of October 6, 2021.
What steps is the Town taking?
- Working through process improvement, the Town of Frederick Public Works Department is working with AquaBackflow to manage the certification process using updated standard operating procedures.
- Annual backflow prevention testing certificates are now sent directly to the Town and AquaBackflow to organize required paperwork.
- Reports are pulled quarterly to check in on the process.
- Information on the backflow testing process can be accessed by all Public Works team members.
- The Town is working in conjunction with Ramey Environmental Compliance who specializes in helping municipalities find the solutions needed to comply with Environmental regulations and fulfill the requirements necessary to properly operate and manage your water resources.
What is a backflow prevention device?
Backflow prevention devices prevent non-potable or undesirable water that is in a building’s water system from backing up and mixing in with drinking water. For example, the device prevents contaminants such as fertilizer and pesticides from entering the flow of potable, drinking water.
Who is required to be tested?
The State of Colorado requires commercial, industrial, and multifamily (more than eight units) users to comply. These types of buildings have larger service lines and therefore pose a greater threat of cross-contamination. These properties are required to have backflow prevention assemblies installed and tested annually.
May 2021: Our water system recently violated a drinking water requirement. Although this situation is not an emergency, as our customers you have a right to know what happened, what you should do, and what we are doing to correct this situation.

Potable Water Supply
Within Frederick’s town limits, there are three entities involved with public potable water supply (water fit for consumption by humans and other animals). Those suppliers are the Town of Frederick, Central Weld County Water District, and Left Hand Water District. All residents on the east side of I-25 are Town of Frederick customers.
If you are a new resident living on the east side of I-25 you are a Town of Frederick water customer. Instructions for setting up utility billing for your new residence can be found here. If you are a resident living on the west side of I-25 you are a customer of Left Hand Water District. For questions regarding utility billing from Left Hand Water District please visit their website.
For certain areas where the town’s distribution system has not been extended, such as Frederick West Business Park, Central Weld County Water District (CWCWD) provides service from their transmission mains. Left Hand Water District supplies all public potable water demand on the west side of Interstate 25 (I-25).
Colorado-Big Thompson Project
The Town’s potable water supply comes from Colorado River water delivered to Carter Lake through the Colorado-Big Thompson Project.
This high-quality source water is treated by CWCWD’s treatment and storage facilities located west of Berthoud, Colorado. A high-pressure CWCWD transmission main transports water to the town’s distribution mains through a number of master meters from which point the town’s water distribution system begins.
Future Potable Water Supplies
To avoid expensive capital investments and to be good stewards of limited natural resources, the Town encourages water conservation through financial and educational means. In order to secure adequate supplies of high-quality water for the Town’s current and future potable supplies, Frederick is one of 14 Northern Colorado water providers involved with the Northern Integrated Supply Project (NISP).
The Town of Frederick has implemented a Raw Water System (RWS) for irrigation to complement the town’s potable water system. The Raw Water System supply is fed from the Lower Boulder Ditch and stored in Milavec Lake. Untreated, non-potable, water is pumped out of Milavec Lake to supply three irrigation ponds on Town property. Two ponds are located on the Bella Rosa Golf Course and the third is located in Centennial Park.
September 8, 2020: What's up with the low water level at Milavec Lake? Think of the lake as a water storage area. In the spring, the lake is filled with water for summer irrigation programs. For example, lake water supplies the sprinklers in our parks. With an expanding raw water irrigation system and hot conditions, more water comes out of the lake, causing the water level to drop. Restrictions determine what water sources can be stored in the lake and when the water sources are available for storage. This is why you see the water level start high in the spring, drop in the summer, and then rise again in the fall.
Raw Water System Expansion
The Town has plans to expand the RWS to a majority of the Town limits. New developments are installing raw water lines to use raw water to irrigate the shared open space and parks. The Town plans to add raw water distribution lines into additional developments as funds allow. There are also plans to develop the Town’s raw water irrigation facilities on the west side of I-25 which the Town has discussed with Left Hand Water District.
