JOLIET, Ill. - The Joliet Fire Department will begin Phase II of its annual hydrant testing program on Monday, June 29, 2026.
Testing will be conducted Monday through Friday from 8:00 a.m. to 4:00 p.m. and is expected to continue for approximately four weeks, depending on weather conditions and emergency call volume.
During Phase II, hydrant testing will take place in the following areas of the City:
Station #5 (661 Mason Ave.):
- The geographical area bounded by Theodore St. to the North, the Des Plaines River to the East, I-80 to the South, and Larkin Ave. to the West.
Station #6 (2049 Oneida St.):
- The geographical area bounded by Theodore St. to the North, Reed St. to the East, I-80 to the South, and Infantry Dr. to the West.
The Fire Department will take precautions to minimize the impact of temporary rusty or discolored water that may occur during hydrant testing.
If rust staining occurs on clothing, the City of Joliet provides a rust-removal treatment that can be used during the washing process. Do not place affected clothing in the dryer until it has been properly rewashed and rinsed using the treatment, as drying may set the stain permanently.
The rust-removal treatment is available at any Joliet Fire Station. Residents who are unable to pick up the product may contact the Water Department at (815) 724-4220 or the Joliet Fire Department at (815) 724-3500 for assistance.
