The Purpose of Hydrant Flushing

In our efforts to provide our customers with high quality water, Fire Hydrant flushing is a part of regular Authority operations and maintenance. Hydrant Flushing is semi-annual maintenance that works to clear the main lines of sediment and to determine that the hydrants are working properly.  When flushing you may experience a loss of water, low pressure or may see some discoloration in your water. This is only a temporary condition and normal service will be restored promptly.  If you have any questions or need additional information please contact our Office at 1-800-356-4168.
