Water Quality

The Western Virginia Water Authority has water treatment processes in place for both water and wastewater that effectively eliminate viruses and harmful bacteria. Even prior to this health crisis, the water treatment process in place for both water and wastewater eliminates viruses such as COVID-19 along with other viral strains and harmful bacteria.

The drinking water is disinfected with chlorine, a required disinfectant added during the treatment process to eliminate bacteria, so that we can deliver safe drinking water to you.  As part of our wastewater treatment, the treated flow is disinfected with sodium hypochlorite, and then that chlorine is neutralized before the treated water is discharged to the river.

For more information about our treatment processes, please see our Drinking Water Sources and Treatment page.

For information about our tertiary wastewater treatment process, please see our Water Pollution Control Plant page.

Important Information About Flushing Your Water Lines

Businesses who have had reduced operations or had their doors shut since the Commonwealth of Virginia Executive Order 53 closed non-essential businesses on March 24, 2020 need to flush the water that is in their internal plumbing pipes before they reopen

The residual chlorine level in the water that has been sitting unused in pipes for a long period of time may have dissipated to a point where the disinfection level is no longer effective at keeping the water within your facility free of bacteria. Therefore, the water in your plumbing pipes may be unsuitable for drinking, showering or other uses.  According to the American Water Works Association, “prolonged building water stagnation can lead to elevated lead, copper, and Legionella levels at the tap.”

Proper flushing clears out the water that became stagnant in internal plumbing pipes during the business closure and replaces it with fresh, disinfected water from the Authority’s distribution system. 

Steps to take to properly flush your internal plumbing lines:

  • Disconnect any spigot aerators or point-of-entry filters.
  • Turn on the cold water for all faucets and shower heads; let the water flow for several minutes after you detect the smell of chlorinated water.(This may take longer and need to be done in stages for large multi-floor buildings or hotels.)
  • Flush all toilets at least twice to empty the tank and flush out the toilet lines.
  • Run all dishwashers for a complete cycle; empty all icemakers – fill and empty the next two batches of ice; flush water from drinking fountains, refrigerator dispensers and spray nozzles.
  • Increase the temperature on the water heater to 140°F for at least 30 minutes. Turn on the hot water at each faucet and run the water to flush the lines and empty the tank.
  • Disinfect any fountains, safety showers, eye wash stations, pools or spas per manufacturer instructions.
  • Follow manufacturer’s instructions for replacing water filters upon completion of flushing.
  • After flushing:Turn off all spigots, wipe down and disinfect all faucets, reset the temperature of the water heater, replace the spigot aerators and reconnect point-of-entry filters.

Help Prevent Sewer Back-ups - No Wipes in the Pipes

When wipes of any type get flushed, they can get caught and cause clogs and sewer back-ups. If wipes reach lift stations that help to convey wastewater towards the treatment plant, they can jam the lift station machinery . The wipes can cause sewer back-ups in your home and result in increased maintenance and the necessary purchase and installment of grinder pumps. These costs, borne by our customers, can be avoided. Please, put wipes of any kind in the trash.
