Drinking water pipes--in the street, leading to your home, or in your home--may be rusting, creating rusty-brown water. Also, your hot water tank may be rusting. If you are having trouble and your neighbors are not, then your own pipes or water heater are probably rusting. Letting the water run for a while will often clear the water (save the rusty water for plants). If the problem persists, call Public Works at (847) 599-6800.
