The Village of Algonquin, IL

×

The Algonquin Public Works Department maintains over 2,000 fire hydrants to ensure reliable fire protection and improve water quality throughout the community.

The Village of Algonquin’s hydrant maintenance program is essential to ensuring reliable fire protection and high water quality across the community. Routine flushing helps improve water quality by circulating fresh water through the system, while painting prevents corrosion and keeps hydrants visible and accessible for emergency responders. This regular upkeep supports a safe, resilient water system for all residents.

Hydrant Flushing

As a regular maintenance practice, the Village of Algonquin Utilities Team flushes fire hydrants throughout the Village twice a year. This exercise not only ensures proper operation of each hydrant, but improves overall water quality by moving fresh water throughout the distribution system.

Residents are encouraged to avoid using water while hydrant flushing is taking place as temporary losses of water pressure and water discoloration may be possible. Running cold water through open faucets for a few minutes will alleviate discoloration. Residents should avoid washing clothing until the water runs clear to prevent clothing stains.

Weather permitting, the upcoming hydrant flushing schedule during weekdays is as follows:

September 3 - September 13: The entire area east of the Fox River to Village limits. (Zone #1 and Zone #2)

September 16 - September 20: The area north of Edgewood Drive and Filip Road, east of Hanson Road, west of the Fox River. This area includes the Arrowhead subdivision, Main Street, and all of Harrison Street (Zone #1 and Zone #3).

September 23 - September 27: The area south of Filip Road, Edgewood Drive, and County Line Road, west of the Fox River, and east of Randall Road (Zone #3 and Zone #4).

September 30 - October 4: The area east of Randall Road, south of Algonquin Road, west of Hanson Road, and north of Country Line Road. This includes Randall Road (Zone #4 and Zone #5)

October 7 - October 11: The area west of Square Barn Road to Village limits (Zone #4 and Zone #5).

October 14 - October 25: The area east of Square Barn Road, west of Randall Road, and south of Algonquin Road (Zone #5).

Hydrant Painting 

The Village routinely hires contractors to paint fire hydrants to enhance visibility, prevent corrosion, and ensure they’re easy to locate in emergencies. During the painting process, each hydrant is inspected for any signs of corrosion. Hydrants are then carefully prepared with a primer, typically white or gray, before being painted in a color that corresponds to its flow rate, making it easily identifiable by first responders. While this work is underway, residents may need to move vehicles parked near hydrants to allow clear access.

This fall, hydrant painting is scheduled through the end of 2024, weather permitting, beginning in late October for hydrants east of the Fox River.
