Water turns brown after a water main break because the sudden change in pressure and flow stirs up natural mineral deposits, iron, and rust sediment that typically sit dormant inside pipes. This dislodged material flows into residential lines, often making the water safe to drink but unappealing.
Key Reasons for Brown Water:
– Sediment & Rust Release: The high-velocity, turbulent flow caused by the breach breaks off accumulated iron and rust from the pipe walls.
– Pressure Changes: When the main is repaired or shut off, air pockets and pressure drops can cause “jolting” or a spike in pressure, releasing sediment into your lines.
– Mineral Accumulation: The brown color is usually caused by iron and manganese deposits that naturally build up, which are easily disturbed during disruptions.
What to Do:
– Flush Cold Water: Run your cold water taps (preferably a tub or utility sink) for 15-30 minutes until it clears.
– Avoid Hot Water: Do not use hot water to prevent drawing the discolored water into your hot water heater.
– Avoid Laundry: Do not wash white laundry until the water is completely clear, as it may stain.
If the water does not clear after a few hours, contact the DPW at (313) 429-1064. If the issues continue you can reach the Mayor at (313) 549-3754.
