As of 2:30 p.m. all 10 Boil Water Notices in Missouri City have been rescinded (lifted) including the 7 managed by Quail Valley Utility District.



While it is safe to use these public water systems, it is highly recommended that residents in these recently impacted Boil Water Notice areas properly prepare in resuming the use of this water.


  • All faucets should be flushed for at least several minutes while taking care not to overflow sinks or create any water damage.

  • Ice maker trays should be emptied and at least one cycle of ice ran and then again discarded.

  • At least one cycle on a washing machine could be ran to flush out any iron or manganese particles before washing clothes.

  • At least one cycle on a dishwasher could be ran before washing dishes.

  • These are only some basic guidelines and are not all inclusive of every situation that all residents will encounter. Some residents may need to repeat these steps if they experience prolonged water quality issues like color, taste, and odor concerns.
