Hydrant flushing is underway in Waukegan’s 5th Ward! This video gives you a behind-the-scenes look at how the process works.
Flushing hydrants is an essential part of maintaining our water system. Each hydrant is typically flushed for about 5 minutes to:
• Clear out sediment from water mains
• Improve overall water quality
• Ensure hydrants are functioning properly for emergency response
During this process, residents may notice:
• Temporary drops in water pressure
• Slight discoloration in water
If this happens, run cold water for a few minutes until it clears.
Our Waukegan Water Utility crews will continue working through the city over the coming weeks as part of this important maintenance effort. Thank you for your patience as we keep Waukegan’s water system safe and reliable.
