Why is my tap water gone brown?


Category: Water quality

If your water suddenly looks discolored, it might be because of a disturbance to nearby water mains, including breaks or repairs. This can also happen if there is construction near your building. Additionally, the use of fire hydrants for firefighting can temporarily cause brown water. Because the water mains are pressurized, a disturbance may stir up or re-suspend sediments, which causes the water to be discolored. Discoloration is typically a temporary condition most often from particles that have settled to the bottom of the water pipes buried under the roadways. Any sudden change in the flow of water within the pipes or outside vibration, may loosen or re-suspend sediment back into the water.
