Coldwater's water distribution system is a complex network of pipes and storage tanks where sediment and deposits may naturally accumulate over time. If not removed (flushed) these materials may cause a decrease in water quality resulting in taste and odor problems, or discoloration of the water. Additionally the CBPU water department is able to test the pressure of the flow for the fire department to ensure the hydrants are functioning properly. During hydrant flushing you may notice a slight discoloration of your water. If this occurs slowly run cold water out of your faucet until the water becomes clear. This is also a good time to flush out your hot water heaters. As always, please proceed with caution when you see workers on the side of the road.
