OKC Utilities says discolored water is safe to drink as officials investigate cause

Oklahoma City Utilities is investigating reports of discolored water in areas served by the Lake Stanley Draper Water Treatment Plant.

City officials said on Monday that the water remains safe to drink and meets drinking water quality standards.

Reports have come from Oklahoma City customers and communities that purchase water from the city, including Norman and Yukon.

Utility officials are investigating the cause, but said naturally occurring iron and manganese could be causing the discoloration.

Laboratory testing is underway to determine the cause, officials said.

The city adjusted its treatment process Monday morning to improve the removal of iron and manganese. However, officials said it will take time for the treated water to move through the large distribution system.

Customers could begin seeing clearer water by Wednesday, but that timing will vary by location, officials said.

“We understand the concern customers have when their water looks different than expected, and our teams are working to identify the cause and address the issue,” Utilities Department Director Chris Browning said in a press release.

Crews are also flushing water lines in areas where customers have reported problems. Officials warned that flushing could temporarily cause additional discoloration.

Those experiencing discolored water should avoid washing light-colored clothing until the water clears, city officials said. The city recommends running cold water from a bathtub faucet for several minutes to see if it clears.

Customers who continue to see discoloration can contact Oklahoma City Utilities Customer Service at 405-297-2833.

This is a developing story.
