The Town of Frisco completed the installation of a Corrosion Control (CCT) system at all four (4) water sources by July 1, 2022. The first treated water was delivered on February 14, 2022 at two (2) of the water sources, while the other two were being outfitted simultaneously. The third water source came online by June 1, 2022, and the last and final was on July 1, 2022. Read More Here…

On September 1, 2021, the Colorado Department of Health and Environment (CDPHE) issued a violation to the Town of Frisco for failure to install corrosion control treatment (CCT) systems at the Town’s three water sources by the August 29, 2021 deadline, and the Town of Frisco must subsequently inform all water customers each 90 days until the corrosion control systems are in place. Frisco’s water division is currently in the process of installing the systems at all four water sources, and anticipates complete installation of the CCT systems by the first quarter of 2022.  Read more here…

During the latest round of testing for the Town of Frisco’s Lead and Copper Monitoring Program for the second half of 2022, lead levels did NOT test in exceedance of the maximum allowable limits.

The Town is now offering free lead and copper testing for homes/buildings built on and before 1987 in the Town of Frisco, as some individual homes in Frisco have tested in exceedance of the maximum allowable limits for lead, which is in exceedance of 15 parts per billion (ppb).

• Frisco has four (4) water sources which have consistently had lead levels registering at below detectable levels (BDL), which means that source water is not the cause of lead levels in individual homes/buildings.
• All of Frisco’s main water lines are constructed out of ductile iron, and all service lines (from the main line to homes) are either copper or galvanized and not lead, indicating that water lines from the water sources to individual buildings/homes are not the source of lead either.

Please email Town of Frisco Water Foreman Ryan Thompson to request a lead sampling kit for your home.

In 2020, the Town of Frisco took part in Colorado’s 2020 Sampling Project by sampling drinking water at three source locations where treated water enters the piping network in town. The 2020 Colorado Sampling Project was in direct response to an emerging public health challenge from a group of chemicals scientifically called per-and polyfluoroalkyl substances or “PFAS.” These chemicals are found in certain classes of firefighting foam as well as in many consumer products, and may cause various health impacts.

To help communities learn if their residents are at risk, the Colorado Department of Public Health and the Environment (CDPHE) offered free testing to public drinking water systems serving communities. Frisco’s results for two specific chemicals currently under the EPA’s health advisory, PFOA and PFOS, were well below the maximum contaminant level of 70 parts per trillion, however the total combined concentration of compounds that fall under the PFAS family, including those not under the EPA health advisory, were slightly above the maximum contaminant level, at 75.4 parts per trillion.

In order for the Town to comply with the Colorado Department of Health and Environment’s requirements for backflow prevention, Council approved amendments to the Town Code that will implement deadlines for property owners to test their backflow devices and submit the results to the Town, and fines for those who fail to do so. Properly working backflow prevention devices keep outgoing water from contaminating source water. These requirements pertain to multi-family and commercial properties rather than individual homes.

The code amendments establish the following:

• Report submission deadlines:
  • Backflow device testing reports for domestic and fire suppression devices must be submitted to the Town no later than September 1 of each year.
  • Backflow device testing reports for irrigation devices must be submitted to the Town no later than July 31 of each year.
• Penalties:
  • The penalty for the first offense will be a mandatory fine of $250.
  • Any subsequent violation will carry a mandatory fine of $500.
  • These fines can be assessed each day the property is out of compliance within a twelve-month period.
