Why does my water sometimes appear rusty?
Discolored water can sometimes occur as a result of fire hydrant testing, valve testing, or work on a nearby water main.

A change in the direction or velocity of water flow water can cause the iron compounds that accumulate in water mains to become suspended in the water, resulting in a discolored appearance.

Typically, our crews will open a nearby fire hydrant to flush out this discolored water before it reaches customers' taps. If you experience discolored water, flush your plumbing by turning on a faucet until the water runs clear. If it persists, call us at (843) 727-6800.
