Drinking Water Protections Against COVID-19 - Officials state there is no need to stock up on surplus bottled water due to Coronavirus

Park City Water Quality experts want to remind residents that their public water supply is safe. In the case of quarantine or outbreak related to the coronavirus, public drinking water systems are designed to continuously deliver safe drinking water to your tap. Marie Owens, Director of Utah Department of Environmental Quality, Division of Drinking Water issued the following statement, “Drinking water treatment and disinfection will safeguard residents against drinking-water-borne viral infections – including coronavirus. There is no need for residents to stock up on surplus bottled water in preparation for a potential outbreak of coronavirus.”

Following Covid Building Un-Occupancy: Bring Building Plumbing Online Ensuring High Quality Drinking Water: Return to Service Guidance

Utah Division of Drinking Water is requesting that public water systems and County Health Departments assist with getting guidance out to assist building owners, property managers, tenants, schools and residences ensure continued high quality drinking water when buildings become occupied again by following the following steps. These steps will help ensure non-stagnant water in smaller and residential buildings, and avoid potential for Legionella in large buildings including hotels.

General guidance:

  • Ensure thorough flushing is conducted until water from the main is flushed at all taps, cold taps first and then hot taps
    • Until cold water at all cold taps or chlorine residual >1 mg/L if pool type test strips available
  • As needed, consult with local plumber to follow these recommended steps

More detailed residential building instructions from American Water Works Association:

  • Remove or bypass devices like point-of-entry treatment units prior to flushing
  • Take steps to prevent backflow or the siphoning of contaminants into plumbing (e.g., close valves separating irrigation systems from home plumbing, disconnect hoses attached to faucets, etc.)
  • Organize flushing to maximize the flow of water (e.g. opening first all cold water outlets simultaneously to flush the service line and then flushing outlets individually starting near where the water enters the structure).
  • Run enough water through all outlets (e.g., hose bibs, faucets, showerheads, toilets, etc.), removing aerators when possible.  Typical durations in existing protocols range from 10 to 30 minutes for each outlet (duration varies based on outlet velocity).
  • Flush hot water lines.  Note: The hot water tank should be drained directly; it can require roughly 45 minutes to fully flush a typical 40-gallon hot water tank.
  • Replace all point-of-use filters, including the filter in refrigerators.  

CDC guidance for large buildings:   

  • These property owners/tenants/property managers/schools need to be aware that Legionella, the bacterium that causes a type of serious lung infection known as Legionnaires’ disease, grows best in building water systems that are not well maintained. Some water systems in buildings have a higher risk for Legionella growth and spread than others.

Park City's household EPA and Utah Division of Drinking Water required Lead and Copper sampling results are well below regulatory action levels. We need 30-additional volunteers to expand our testing base to continue to validate that lead is not a concern in Park City drinking water. If interested in participating in this Free Lead and Copper testing program, please fill out this survey: Lead and Copper Survey to see if your home qualifies. If your household pipes are plastic or if you have a whole house water treatment system, the home does not qualify for testing. Please call us at 435-615-5335 if you ever have questions about your drinking water quality.

Annual Water Quality Consumer Confidence Report

The Park City Water Department, as required by the United States Environmental Protection Agency (EPA) and the Utah State Division of Drinking Water (DDW), annually publishes the Water Quality Consumer Confidence Report (CCR) (Leer en Español). The CCR provides information about the sources of water and the treatment facilities that are operated by Water Department staff in addition to other EPA required information. The CCR reports the highest and lowest levels of each parameter that is detected from the sources that supply water to the distribution system. Many other parameters are tested for and if they are not detected EPA recommends against including these parameters in the CCR. The CCR also includes results for some parameters that are collected in the distribution system, such as total coliforms, chlorine residuals, disinfectant by-products, and others from within buildings, such as lead and copper.
