Sac City officials want to remind residents that hydrants flushing is scheduled for this week and is expected to be finished on Friday. Flushing hydrants is regular scheduled maintenance where water is pushed through lines at a high rate, which removes possible mineral build up, while ensuring the hydrant is functioning properly and flow rates are adequate. Consumers in the area where the flushing is taking place may expect some low pressure for a short time, but it will return to normal. Individuals may call the Sac City Water Department Office at 712-662-7692 with any questions or concerns.
