WORLD HEALTH ORGANIZATION’s March, 2020 Technical Brief:  Persistence of the COVID-19 virus in drinking-water, feces/sewage and surfaces (WHO) – “While persistence in drinking-water is possible, there is no current evidence that surrogate human coronaviruses are present in surface or groundwater sources or transmitted through contaminated drinking-water.  COVID-19 virus is an enveloped virus, with a fragile outer membrane. Enveloped viruses, generally, are less stable in the environment and are more susceptible to oxidants, like chlorine.” All Cross Timbers WSC water is treated with chlorine and laboratory-tested weekly to ensure contaminants are not present.  Water is an essential service and Cross Timbers WSC is well-prepared to manage its response to COVID-19Cross Timbers WSC has an existing emergency response plan and is continuing to modify and update, as needed, in response to the most current available information.  Cross Timbers WSC has back-up power and in emergency situations can be operated with a small number of staff.

U.S. Centers for Disease Control (CDC) Coronavirus Disease 2019 (COVID-19) and Water:  March 13, 2020

  • The COVID-19 virus has not been detected in drinking water.  Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19.
  • The risk of transmission of COVID-19 from the feces of an infected person is also unknown. The risk is expected to be low, however, based on data from previous outbreaks of related coronaviruses.  There have been no reports of fecal-oral transmission of COVID-19 to date.
  • At this time, the risk of transmission of the virus that causes COVID-19 through sewage systems is thought to be low.  Although transmission of COVID-19 through sewage may be possible, there is no evidence to date that this has occurred. SARS, a similar coronavirus, has been detected in untreated sewage for up to 2 to 14 days with documented transmission associated with sewage aerosols (source: CDC).

Cross Timbers WSC will continue to monitor the situation and post any updates on this web site.

Based on the above information and in accordance with state and federal guidelines, the Board of Directors postponed the Annual Meeting scheduled for April 20, 2020 until a later date.  Details related to the Annual Meeting including a time, place, and agenda will be provided 30 days prior to the scheduled meeting.  We continue to work diligently to ensure you have a safe and adequate supply of water.  Cross Timbers WSC thanks you for your cooperation during this difficult time.
