Drinking Water Issue Corrected

Customers of the Norman Public Water Supply were notified of a problem with the water supply in the area north of Robinson and east of Flood on Friday, May 7, and were advised to boil water before consumption. 

We are pleased to report that the problem has been corrected and that it is no longer necessary to boil the water before consumption. 

We apologize for any inconvenience and thank you for your patience. 

The City continues to investigate the cause of the contamination and suspects it to be an issue related to work on an ongoing water well project. Crews have turned off water from the well field. Chlorinated water from the water treatment plant and OKC will continue to be used while the source of the problem is identified and corrected.

Residents are advised to “flush” their water following the lifting of the boil order to clear plumbing of potentially contaminated water. Flushing your household and building water lines includes interior and exterior faucets, showers, water and ice dispensers, water treatment units, and so on.

Please follow these guidelines:

  • Clean aerators: remove all aerators from faucets and soak in bleach.
  • Faucets: flush 5 minutes with cold water. For a residence with multiple levels, start at the top of the house.
  • Showers: flush 5 minutes of a mix of hot and cold water.
  • Toilets: flush and clean each toilet.
  • Washing Machines: none required.
  • Dish Washers: if your machine has a sanitize cycle, run 1 cycle.
  • Outdoor Spigots; 5 minutes, disconnect hose first.
  • Refrigerator Water Dispenser: flush for 5 minutes or at least 1 quart of water.
  • Faucet/Fridge Water Filters: consider replacing filter per manufacturer recommendation.
  • In-Line Water Filter: consider replacing filter per manufacturer recommendation.
  • Ice Makers: dump all existing ice and discard new ice made over an additional 24 hour period to assure complete purging of the water supply line. Wash and sanitize ice bin.
  • Food and Baby Formula: be sure you have discarded any baby formula or other foods prepared with water on the days of the boil order. (If unsure of the dates contact your water department.)
  • Water Heaters: run hot water from all faucets until water runs cold. Second option is to drain the water heater using spigot/release on the bottom of heater.
  • Water Softeners: cycle water softener per manufacturer recommendation.
  • Soft Drink Dispensers: disconnect flavoring and cycle water through until replaced with fresh water, reconnect flavoring.

Due to the flushing of the water lines by residents and the flushing of the hydrants, some customers may experience discolored water. However, this is an expected result and does not pose a health risk.

Contact your local Water Department if you have any questions. General guidelines on ways to lessen the risk of infection by microbes are available from the EPA Safe Drinking Water Hotline at 1-800-426-4791.
