Smithfield, NC -- Many non-essential businesses, retail stores, churches and other facilities have remained closed in recent weeks due to COVID-19.  When little or no water is used over a period of time, degradation of water quality can occur within the plumbing system, including pipes, tanks and appliances.  These conditions increase the risk for the growth and spread of waterborne bacteria, such as Legionella or biofilm, in the building piping.  Disinfectant in the water, such as chlorine, will likely dissipate or become undetectable when water is held in the plumbing system with no usage. 

Actions are recommended to ensure the water in the building is safe as well as taste and odor free before resumption of normal water use.  The Center for Disease Control (CDC) has very detailed information on flushing and reactivating plumbing systems after dormant conditions.  A link to these recommendations and information from the Environmental Science Policy & Research Institute can be found on the Johnston County Public Utilities website at under the headline “Important Water Safety Precautions as Business Re-Opens.”
