An estimated 5,650 water customers in a large swath of Beaverton are under an alert to boil water before using, after a water valve broke Wednesday afternoon.
Tualatin Valley Water District issued the alert for customers south of Southwest Farmington Road. As a precaution, Tualatin Valley Water District customers in the region are advised to boil their water until further notice.

The area extends south into Cooper Mountain Park, past Southwest Kemmer and Weir roads.
"The issue is being corrected and once finished, we will flush the water lines and collect samples to confirm that your drinking water is safe and meets all applicable water quality standards," according to a release from the water district.
The testing process requires 24 hours to complete. The water district is investigating what caused the valve on the water main to break.
Customers within the affected area should disinfect their water by doing one of the following:
• Bringing water to a rolling boil for 1 minute, then cooling.
• Using bottled water.
• Using bleach: Add 8 drops of unscented household bleach per 1 gallon of water if the water is clear. If the water is cloudy, use 16 drops of bleach per gallon. Mix well and let sit for 30 minutes.
• Use water purification tablets according to the instructions.
Customers should use boiled water until the district notifies the community that the water is safe. The boil-water notice will be lifted when testing results show no contamination.
