Statement on discolored water in Detroit
“GLWA received a request for assistance from DWSD on June 29, 2021, concerning rusty/discolored water complaints from Detroit residents. GLWA and DWSD are working to locate the cause of the discolored water, and that investigation is ongoing and has included hydrant flushing in the city of Detroit, which can temporarily cause discoloration of the water.
When rusty-brown, orange or light-yellow water is experienced it is not normally a health concern but one of aesthetic quality. Operating valves, hydrant flushing, routine maintenance and construction work are some of the causes for discolored water.
Residents experiencing discoloration are advised not to use the water for laundry and other household uses that may result in the staining of fabrics, until it turns clear. Boiling the water will not improve the discoloration. Residents should periodically check their water every one to two hours by running it for about three minutes to see if it is clear. If it clears, then they should flush the household plumbing by first removing all aerators and running all the cold-water taps, including the bathtub and sink, and flush each toilet at least once. All taps need to be open at once to ensure that all the water in the pipes is replaced with the clear water from the water main. Once the water is clear, the water can be utilized as a resident normally would.”
