The Water Division regularly exercises and maintains approximately 800 fire hydrants in the City of Zion.
All fire hydrants are flushed on a yearly basis. Hydrants are flushed to help improve water quality. For example, flushing helps maintain good chlorine residual throughout the system, as well as helps reduce scale from the water main. Flushing every hydrant on a yearly basis is also a great preventative maintenance. It allows the opportunity to inspect each hydrant and make sure they are in good working order.
Hydrant flushing is done in the fall. The schedule is published in the paper. Please be advised not to do any washing on the day of hydrant flushing. It is also recommended that you not wash until 4:00 P.M. the following day of flushing hydrants in your area.
It is unlawful for any person not authorized by the superintendent of water and sewer to tamper with, alter or injure any part of the city waterworks or supply system or any meter.
It is unlawful for any person not authorized to use water from city fire hydrants. Persons receiving permission to utilize a hydrant from the Department of Public Works must utilize a hydrant meter provided by the City. A deposit is required to obtain one of these meters.
