Discoloration can occur in a water system when significant increases of flow through the water lines stirs up the natural minerals that have settled during periods of lower flow. This persists until the sediment is flushed out of the system.

So, what causes an increase in the flow of water in the lines?

This is a common occurrence in the summer months when the temperature rises and water consumption increases. Our customers use an average of 10 million gallons of water each day. However, during the sweltering days of summer, that number rises as high as 18 million gallons a day.

When there is that much water being pumped through the underground lines, the velocity can stir up mineral scale that has settled in the pipe and ultimately come out of your tap.

While the color is not aesthetically pleasing, the water is safe. However, it is prudent to flush the discolored water as much as possible before drinking it.

You will want to avoid using hot water while you see discoloration to keep from pulling water into your hot water heater. Also, some of the minerals from discolored water may stain clothing, so it's best to postpone washing light-colored laundry.
